what is normal turbo sound for a TDI?

[sootyscottie]

Just a quick question to settle my mind.

I have just bought an 05 2.0TDI sportback with 70k on the clock.

This is my first diesel car , and my last 2 cars were both 1.8t petrol engines (Seat leon cupra and cupra r).

My question is about turbo dump noise on gear change.

Basically, i am quite suprised at how loud it is on a diesel. When driving in a built up aread, ie high street etc, i can distinctly hear the turbo dump. It is not loud enough to turn heads, but i can definately hear it quite clearly. Also, i can occasionally hear a slight 'chatter' noise after the dump. (this is the best word i can use to explain). I have never really been able to hear the 'dump' on the petrol turbos, as they were recirculating, so am i right in saying that the diesel does not recirc?

Basically i want to know if this is normal, because if it isn't, i would like to get it sorted out.

Thanks in advance :Blush:

[eko]

On my 2.0 tdi Passat when I change the gear I can hear the ‘pressure release’ from the dump valve. It is quite loud. However, I do not hear any other noise. I hope this helps.

[Crasher]

They do get noisy as the turbo is failing which is an extremely common problem on that engine.

[sootyscottie]

When you say failing, do you mean it will be likely to die soon or just general wear and tear , so will perform the same ,all be it a bit noisier?

[Crasher]

They start wheezing and whining and then start losing oil. It is such a common problem that my local TPS (VAG genuine parts) keeps two in stock at all times. Lots of other VAG turbo’s are unreliable and they are all to order, not in stock-it is that much of a problem. One local taxi company had seven Octavia 2’s with the BKD 2.0 16v engine, we serviced them all and five out of them had failed turbo’s at less than 50K.

[sootyscottie]

What would be a good check to see if the turbo is failing?
Would any error codes get thrown up or is there some other way of checking to see the condition of the turbo. ( apart from taking it off that is :) )

[Crasher]

They do throw out error codes but apart from excessive oil in the change pressure system and odd noises, there isn’t much warning until they fail.

[sootyscottie]

Thanks for the info crasher.
Looks like i shall just wait and see if the turbo goes:P
I can guarantee that it will fail just after my warranty ends !

[allycooke]

They do get noisy as the turbo is failing which is an extremely common problem on that engine.

does anyone have any further details on noisy (whine / whine'ing) turbos on the 2.0 tdi engine.

my 56 plate 2.0tdi (170 quattro) has started making a horrible whistling (almost like a distant police siren) sound between idle - 2000rpm. I should also add that it only has 35k on the clock.

the Dealer has confirmed there are no technical or performance related problems - no errors being shown on the ol' compooter. however AUDI UK say this is due to a chance in "pitch" of the turbo fan which can happen and say i should just live with it.

however I'm not happy with this response as the "whistle" is noticeable even above the radio/fan - and to be honest to me sounds like it's on it's way out. the car still has warranty for another 12 months...and it sounds more like AUDI UK don't want to pay for the £2500 turbo replacement.

anyone else successfully had Audi replace the turbo? or worse had a failure because Audi UK wouldn't cough up.

cheers, Al

[allycooke]

Audi UK are still sticking to their guns - no replacement on the turbo unless it is impacts the performance. I don't think AUDI UK understand I don't want a new turbo..I just want the whistling/whining noise to go away. it was there for the previous 30k and I don't buy into the "pitch" change story.

however their is some possible good news......the dealer mentioned that on their recent master-technician conf call my car was raised in the Q&A by Audi UK and another dealer mentioned a Turbo "software" upgrade fixed a similar problem on a car they had with the same problem.

So the update CD is now on order for my car...and fingers are crossed it's a turbo mapping issue and the upgrade / change will stop the noise.

I'll keep ya all posted.

[turpal]

2.0tdi th noises u guys described sound like turbo is nearly gone,had to replace on my car at 83000m,If u can only hear it in going pass a fence or narrow build up area wit a window down it is ok,but mine was wistling as from 1100rpm which u could hear in an open field with your windows shut.I went for a rebuilt unit `cos they rebuilt older units which last for ages and I thought original manufacturer probably uses some new components which don`t always prove to be good and rebulding companies might use a better proven stuff.Anyway that`s my opinion.Also I am not going to use long servise oil and do 20000miles,personally I recommend to use normal pd full sinthetic and change 6-7k max.That way your engine is clean oil seals good.Also DO NOT rev cold engine,let it warm up.

[Bryston]

Hi guys - i am new to Audi forums in general as i bought my 1st Audi in November 2008. I have the A3 TDi 140 sportback 05 reg and i have had a remap taking it to about 180BHP'ish on New Years Eve (a late Xmas present to myself :-)

Prior to the remap i did notice that at about 1900rpm there was a whistle noise (like tssssss). After the remap the power was much more smooth, extended through the range and generally MUCH better (i would NOT change back)

However, a few days later i noticed that about 1000rpm to about 1500rpm there is a different whistling noise. It sounds like a distant Police cars siren.

Basically - does anyone know what it is? (serious or not?)

I am contacting the company who did the remap to hear what they say - i hope it is just extra air being fed into the system early on in the rev range, that gives me the better throttle response in low revs.

Of course this is wishful thinking - as the LAST thing i want to hear is that the TURBO is screwed.

My mate (a 400-BHP TT fan) thinks it could be a turbo leak - if it is - how do I fix this - what should I do?

Sorry for so many questions - hopefully the original post will have an answer to this subject too!!

All the best

[Crasher]

The police car siren analogy on the BKD code engine is one commonly used to describe the sound of a dying turbo. Not the remapping companies fault, it is just what the BKD turbo’s do, they are THE most unreliable turbo VAG have ever fitted.

[Bryston]

Oh Great!!

[Bryston]

Maybe there is a scientific reason for the failed turbo - is anyone knowledgable on the subject?

[Crasher]

Ohh so you don’t consider me knowledgeable on the subject-thanks!

[Bryston]

Scientific means - specific reasons - rather than BKD's have this as a common problem or "BKD code engine is one commonly used to describe the sound of a dying turbo" - that is all...

[Crasher]

It would have been more polite if you had asked my opinion as to why I think the turbo is more prone to failure than those fitted to other models. If you look at your question it should not be difficult to see why I took offence.

The main reason BKD turbo’s fail is poor lubrication due to the VAG specified Longlife service intervals. The BKD’s turbo is a hard working unit in order to give quick responses and this means it places a lot of strain on the oil, breaking down the long chain molecules in the oil faster than would be experienced in less stressed applications. Doubling up the oil and filter changes appears to effect a solution to the problem.

[turpal]

Hi Crasher again.My touran is BKD engine and just have fitted a new (recond.)turbo.I was thinking if I use a normal service full snthk pd oil and change it like every 6k help at all?Can u actually fit a more reliable turbo to it?Thanks.

[Crasher]

Use Longlife 3 spec oil and change it at normal intervals. I don’t know if it is possible to improve the turbo’s reliability, we just fit genuine VAG units with a two year parts and labour warranty and so far so good when changing the oil annually/10k intervals.

[allycooke]

I'll keep ya all posted.

The update did nothing to improve the "whistle/whine" which is best described as a distance police siren.

So it's a case of living with it - fortunately the car is in warranty until December this year, and with me already reporting this to Audi as "suspicious noise" the Dealer Service Manager says he'll make sure Audi look after me even if it fails in 24 months time.

Interesting point though is that the Engine in my A3 (170bhp) 2.0tdi quattro is type "BNM", and we took another BNM A3 with 140bhp 2wd out with only 6k on the clock from their used-stock and it makes exactly the same noise.

So common it seems - just strange with my car how the whistle/whine only developed after 20k mileage.

[HairyG]

I've read the whole thread with interest, and a nasty sinking feeling.

SWMBO has just bought an 05 A3 1.9 TDi Sportback with 67,000 miles. I can hear a noise like a distant police siren when I drive it.

How can I tell if this car has a BKD engine with the poor quality turbos as described?

Apart from that, it seems like a very nice comfortable car, drives well, looks good etc.

[Crasher]

Service book, reg document, data sticker on the boot floor, registration document, all have the engine code on.

[Nigel F]

Hi Everyone, another newbie here...and a worried one at that. Yesteday i bought a MKV 2005 Golf GT TDI 4 motion from a local garage with 3 mths warranty. I too have got this "police car" sound and after reading Crasher's comments i am very worried. I have today had an oil and filter change using castrol Edge 5w-30.

I wonder if Crasher could tell me if my turbo is on it's way out and if so, what kind of cost am i looking at, or can it be saved. I have not spoken to the garage i bought it from yet as i only noticed it tonight but, i guess because the turbo has not yet failed they won't be interested.

Any advice would be much appreciated.

Regards, Nige

[Crasher]

I would need to hear the noise directly and that would not be easy unless you are close.

[Nigel F]

Thanks for the fast reply Crasher, I live near Manchester but, the noise is definately like a police siren in the distance as i kept looking round for police cars until i realised it was coming from the engine bay and it is the bkd engine.

Regards, Nige

[Nigel F]

Crasher, If it is a " dying turbo " does it need to be replaced sooner rather than later and what kind of cost would i be looking at please.

Thanks, Nige

[Crasher]

The BKD turbo is noisy from new, some more so than others. The turbo on the BKD is also chronically unreliable but not even VAG dealers will change one until it actually fails. They have become so accustomed to complaints over the noise and requests for them to be changed that they just refuse to do anything until it fails. Threats, Trading Standards, arguments and even legal action have no effect on their response. If it came from a non franchised dealer, I doubt you will get anywhere. The standard response is “they all do that sir” and in this instance, they do!

[samb666]

For the sake of consistency I'll stick my question in here as well - a few weeks ago I bought an Audi A6 2.7 TDI (55 plate, 55k)... my first diesel or turbo after outgrowing my Type-R. The car is amazing and engine is very quiet/smooth compared to my other limited experience of diesels, but it does make a kind of whirring noise as it drops revs i.e. when changing up gears (or presing the clutch to listen for it!), this is only really audiable over ~2000 rpm.

It's hard to pick the noise out when there is any weight on the engine, so it doesn't sound similar to the other questions I can find on Turbo noises. Could it just be the turbo 'dumping'? It sounds more mechanical than I would expect, but it seems to be too high pitch to be the whole engine spinning down?

I plan take it to a garage to have it looked at but wondred if anyone had any idea what it might be - especially as I don't yet have an Audi garage I 'trust' after years of great service from ABP Motorsport in Crewe.

Thanks!

[Crasher]

It will need an experienced ear to listen to it.

[samb666]

Hi...

I found someone at work who has had a few Audi A4 turbos, both petrol and diesel, we went for a drive and he say's they've all made the same noise, though not sure if its the engine - I guess it just sounds different to other TDIs I've driven because the diesel rumble isn't there to cover it up. Will check it out when I get it serviced in a month or so anyway... Thanks for your response though!

[neil mahoney]

hi, i have a golf mk5 140 with the BKD engine, i also have all the signs of a problem turbo,i was just wondering what in the turbo causes this [ distant police siren sound] and why is it only when going slow and the lower revs range this sound is at its worse? i find that at around 30mph and still low revs , i cant hear it, thanks in advance for any replys:beerchug:

[turpal]

I have BKD engine as well,changed turbo 1500miles ago(at 83000miles).I can hear a slight sound on low revs even now wich is normal,but it was much louder befor I changed it.My car was serviced at VW all the time(long service).As CRASHER (also a member here) who knows about VAG cars a long service is not a good idea for these engines,use a longlife oil and change it about 9-10k.If it comes to the worst and u need a new unit shop around,I got mine from ESSEX TURBOS in Witham.They have a good reputation and it comes with 12month unlimited miles warranty,cost me £385+VAT=£442.They do deliver,if you need their cantact number or location let me know.Just remembered i had a bit of oil in the pipe coming from turbo.Anyway see if you need 1 first.Crasher is in Nottingam,he said they do 2years parts and labour if Im not mistaking,but I don`t know how much.I paid £160 for fitting.Good luck.

[Crasher]

Genuine turbo (£1200) and a days labour, much more than you paid.

[turpal]

It was a good deal.As I do a taxi 12month unlimited suits me fine `cos I do about 50-60k miles.Genuine turbo is about that much(£1200) Labour is 4hours by book and I paid £40/hour,vw£105.

[paz2834]

My 2.0 GT TDI golf turbo gave up this week after showing no signs of trouble at all. my turbo always had a whistle, but only started to 'chatter' after it blew. The car had only done 26k and I had it 3 weeks. Luckily still just covered by manufactures warranty

[brgsstm]

now i am a worried n00bie! I just bought an 04 A3 2.0 Tdi 140 and I have the police following me!! Sounds like a new tubo could be on the way! :(

[Bryston]

There are more comments about the Owl noise here - different car but same symptom...

http://briskoda.net/octavia-ii/octy-2-0-tdi-do-they-all-whistle/125940/

[Crasher]

Different car maybe but the engine is the same, a BKD.

[cyrusK]

Hi,Is the turbo causing all this bother specific to the BKD engine or is it used for other types as well?

[Crasher]

It is used and a problem on the Golf 5, Golf Plus, Jetta 5, Touran, A3, Octavia 2, Leon, Altea, Toledo with the BKD engine. The replacement units appear to be much more reliable but it is early days.

[Bryston]

I spoke to the local Audi who said the noise was ermm - if you complain loud enough sir, i can suggest you need a new turbo otherwise it is fine - sorry i can't help anymore.

After looking on numerous forums, i am yet to find a reason for the whistling noise that sounds like an owl/police siren. It must be air/gas escaping/being released from somewhere - i can make the same sound with my mouth and lips....which parts of an engine are responsible - it can't be such a difficult question surely..i think a previous post mentioned oil was related - i'm thinking air/gas still - any ideas people??

[Crasher]

A turbo is a shaft with two turbines spinning on it at around 150,000 rpm. If you think a tiny fault in the finish or alignment of the turbine blades will alter the way the air flows, you don’t need to imagine why it will make a noise.

[Bryston]

"If you think a tiny fault in the finish or alignment of the turbine blades will alter the way the air flows"

I give up with you - 1st you mention oil now you mention aligment of turbine blades! no mention of how the whistle noise starts....

[Crasher]

You give up with me, how do you think I feel living with me for the last 45 years!

If you don’t understand how a turbo works you can do a few searches on this but it is very difficult to explain defects in alignment or surface finish and how they make or alter the audible performance of a turbo. Think of it like a child’s fairground toy windmill, if you blow on it, it makes a noise and if you alter the angle you blow on it the noise changes. Does that help? I am not a very good teacher, “those that can do, those that can’t-teach”.

[onzarob]

, “those that can do, those that can’t-teach”.
:biglaugh:Crying.

I've got a Golf with a BKD, time will tell, My neighbours had one from new done 70k and no issues. So not all bad. The turbo sounds no different in mine to my AFN 1.9.;)

[Crasher]

No, the police sirens following you are for real!

[speed12]

Is this a common problem on the older 1.9tdi's?

I have an 05 bora TDI 130. My turbo has always made a whistle, but I quite like it, living on a farm pretty much all turbo diesel tractors, lorries etc do make a whistle.

I dont think I have heard any siren type noises coming from my car, sometimes at low speeds in 2nd I hear a very faint whine, but I think thats more transmission.

All these problems with turbo engines are on reason why I am considering going for a simple straight 6 petrol!

[Crasher]

Do you mean “the car of the devil”

[zollaf]

nah, an old Jag.

[speed12]

Lol,

Car of the devil?? you mean a BMW????

I seem to remember when I mentioned that I had considered a BMW 3 series you said you would never speak to me again??

Well the thought had crossed my mind, and I do fancy a Z4 3.0, however something has come up regarding a potential barn conversion, so I need to do some serious thinking over the next few weeks.

Despite my TDI performing really well so far (Touch wood) i still think its just a matter of time before something big happens, i.e. clutch failure, turbo failure etc and the costs to put right are scary.

Im also beginning to doubt whether Diesel cars are really much cheaper to run than petrol, especially considering the average price difference is 13ppl.... Im sure this gap will get bigger in the future as demand for Diesel increases.

[Crasher]

Yes, that manufactures product is what I mean.

I think that you have to do some serious miles to make a diesel pay, the pence per litre and increased servicing/repair costs just don’t add up for me and I still can’t get on with the harsh running, petrol all the way for me.

[allycooke]

Crasher - my A3 still whines - December is fast approaching (and thus the warranty expires) - Audi mentioned they would look after me if the unit fails even after this date (time will tell).

But I'm starting to wonder if remapping the turbo would / could potentially change the whistle? or would it potentially make it worse?

I think i've seen it's quite easy to improve BHP by 5-10 on the 170 and improve fuel economy as well. or even add 20 - 30 BHP with a race / sport mapping?

[Bryston]

My police siren noise is slightly louder now and extends to just beyond 2000rpm which basically means it is getting worse. I have have made enquiries into a new turbo. 5000 miles travelled since it first was heard.

Audi say £1400 or similar or eurocarparts OE £750 http://www.eurocarparts.com/ecp/c/Audi_A3_2.0_2005/p/Car-Parts/Engine-Parts/Turbos/Turbo-Chargers/?719441460&1&a396fa74fdc0a67856808aa349a24d6561a59679

The car has a remap - 140 bhp to maybe 180, should i tell the garage fitting the turbo or not mention anything? I still want to keep the map and the extra power. I doubt very much if i will use Audi to do the turbo replacement - it will be an independant.

Cheers

[Crasher]

5 to 10PS! And the rest! Any re-mapping puts more stress on the blower and quite rightly if the car is re-mapped Audi and any replacement unit supplier have the right to refuse a warranty. Even if a non Audi dealer does the work I suggest a genuine supplied turbo is used, that way you get the full two year genuine parts and labour warranty.

[allycooke]

fair enough - I was thinking I had seen a "Economy" mapping somwhere that mainly improved MPG and but still resulted in a small increase to BHP. I guess if my turbo is whistling and whining it's going to do it regardless of the mapping.

[nc7503]

i have a 1.9tdi 105ps jetta.i have had this owl/hooting sound for 6 months now it only happens at low revs changing up the gears only.it has been to vw 3 times for this finally i got to take the mecanhic out in my car to let him hear this noise. soon as he heard it he said strange that noise normally effects 1.9tdi o5 passats:confused: anyway cut along story short this problem has been cured by vw replacing the centre section of my exhaust for one off a 2.0tdi so vw inform me. ive had a look underneath my car and there is shiny new centre section there.... the only question i have is how come changing this section has cured the hooting sound:confused: if anyone has any ideas let me now.

[MFGF]

Hmmm - my wife's A3 2.0 TDi has "hooted" like this on a light throttle since she picked it up new in July 2004. It hasn't got any better or worse since then, but in all that time she's only managed to rack up 26k miles. If it ever starts to get louder, we will think about replacing the car. If I hadn't seen some of the horrors detailed in this thread, I'd have said it was normal...

MF.

[nc7503]

now my car has started sounding like i have my own police siren under the bonnet.this is only when the car is warm and been driven in 1st and 2nd gear!:zx11: i spoke to vw today who said it more than likely that the turbo veins/splines are bent (out of balance):confused: it goes in friday to have this problem fixed. why is this???, i dont drive the car hard and ive only got 36k on the clock. ive had the car since march this year along with a new egr valve,centre section of the exhaust replaced and now the turbo playing up im thinking of getting shot of the dam thing.i thought vw's were supposed to be bullitproof!:zx11:

[allycooke]

as Crasher has said previously - sounds like you have a BKD engine (I'd ask VW on Friday)and if so...I think your going to have to live with the police siren....like I have to with my A3 2.0 TDI quattro (170).

but if they do manage to fix it and you do have a BKD engine let me know what they did to fix it :) cheers, Al

[Peter_]

My car (BKD) had this exact "police siren" sound from the turbo (13k miles at the time) and was replaced under warranty. They said it was likely due to bearings being worn due to lack of lubrication. An independent garage recommended that whenever I use the car always try and remember to let the engine idle for 30 seconds before switching it off to allow some oil to go in the turbo for when you start it next time from cold, which I do when I remember!

[Bryston]

Hi Peter - has the noise returned since you had the new turbo? How many miles has the new one done?

[Peter_]

No - its seems fine now, have covered 8k miles or so.

[FSOMarc]

[URL deleted]

apparently the turbo whistle is supposed to be there

[Crasher]

Whistle yes, hooting owl or following police siren, no. It certainly isn’t there when you fit a new blower.

[Bryston]

Hi all,

I agree with Crasher - mine started a police siren noise at 32k and now its at 45k - the police siren noise is much worse, it even happens quietly when at idle now which it didn't before and extends to 2300 rpm. This is not normal at all and is more than likely the bearings on the turbo worn due to spindle mis-alignment or the seals perished due to a number of reasons.

I am getting mine looked at and hopefully fixed once the snow goes:)

Question - my A3 140 tdi is re-mapped to approx 175bhp - if a new turbo goes on, do i need to treat it gentle at first whilst it beds in or is it fine to drive normal?

Cheers

[allycooke]

will be interesting to see Bryston if Audi change your blower. My dealer still says the official line from Audi is "it's within spec" and unless the turbo fails they won't change it....i guess they are trying to prevent a mass recall for all whistlers.....

the dealership did say that even if it fails now (as my warranty is up) they would still replace FOC because I've reported (and they've investigated) before the warranty period expired.

My A3 is now up to 52k and still makes the same hooting/police siren noise it has been doing since 23k

[robmac]

Just bought a 2006 1.9 as tdi with a BXE engine and it's got the old siren whining from 1000-2000rpm.

seen a turbo that might be good as a back up just in case mine fails the part code of the potential replacement turbo is V03G253 014F

any ideas if this will fit?

[Crasher]

03G 253 014 F is suitable for a BXE engine in an A3.

[robmac]

nice one, thanks Crasher.

[Buzzoff]

Hello Chaps,

I'm looking at buying a golf gt tdi 140 (mk5) BKD engine code.

The car in question has done 95K with full vwsh, I have spoken to a VW dealership who have confirmed the service history (4 long life services and the last was a 10K oil service, so the service history stacks up atleast).

I'm now going to be listening out for this turbo issue, my question is will I need to drive with the window down to hear the police car siren or will it be obvious from inside the car (windows up)?

Is the sound present on tick over with bonnet open or closed?

I'm going to give it a good run and I'll also leave it to tick over and see if there is a hot start issue.

What do you guys think?

Dan

[robmac]

you can hear it on mine, inside with the windows shut. It is not present on idle only when accelerating at low revs 1000-2000rpm in second and third, it goes at just over 2000.

from what i've read this is the early stages and even with this noise audi say it is within tolerances and will note replace until it blows.

That said it is a tad annoying but the car pulls well and drives real nice.

[onzarob]

Dan, if your buying from a dealer just make sure you got a good warranty. I doubt you will hear anything that isnt normal. If buying from a small indy dealer make sure the warranty covers the turbo. ;)

[nc7503]

finally i had my turbo replaced today (warranty)no more stupid police siren sound between 1000/2000rpm,it was sending me round the twist, its taken 4 months, countless phone calls and emails to get it fixed. the dealer hates me:D as i have taken advantage of my warranty probably to many times.i asked the question of what was actually causing this sound which was met with the reply of....... does it matter sir you have had it fixed now. i asked to speak to the service manager..... he was out!! im getting more and more racked off with the main dealers as there whole attitude stinks,its not my fault that my car has had problems. they even questioned that ive had the cambelt changed at a vw independent. which i replied block exemption!!

[Buzzoff]

Thats a first class result, well done:approve:

Regarding my purchase of a golf gt tdi 140, I bought one last Saturday.

After spending the weekend before driving 450 miles all over the place and being offered rubbish from car dealers and traders I decided to avoid any trade seller and go private.

I've picked up a 05 model with 88K on the clock a good service history and what I did like about the car was that apart from the first owner (VW main dealer in Kent as a demonstrator) the two owners were private and not a rep mobile.

It is a darkish metallic pearl blue (not sure of the name) it's got lots of toys and best of all dealer upgraded 17" 10 spoke split rim alloys (225 tyres).

The golf goes well and is a joy to drive on the twisty bits too.

One thing I have had to do was to replace the rear tyres seeing that the Bridgestone potenzas were mis-shaped on the inside edges. I understand this is a common issue.

I'm also planning to do an oil service soon and I'll carry on dumping the oil after 5/6K miles (I'll use Quantum full synthetic oil instead of the Longlife oil).

Cheers,

Dan

[Buzzoff]

Oh I forgot to say one Gt tdi 140 I took out on road test had the invisible police car chasing it. Even though I drove 100 miles to see it with full VAG history I did not bother with it thanks to your good advice.

The trader selling it thought he had a sale (seeing I had driven 100 miles on a Sunday morning) I told him he had wasted my time seeing I did ask him the question regarding the siren noise and he said it was fine..........

Thanks again for your fantastic advice:approve:

Cheers,

Dan

I think the problem is what Crasher said I believe....it's related to the positioning to the blades in the turbo fan that causes the whistle at certain rotation speeds.

I guess Audi are taking the view if the customer can live with the noise then we can save ourselves the ££ in replacing it. And the stock answer is "if it's not affecting performance - we'll continue to monitor the situation sir/madam".

I betcha the newer models don't have this same issue. so it's probably just us with BKN/BKD series engines :-( humf

Hi Gents


ive just joined and just aquired a nice 40k A3 2005 Sport with the BKD engine (and 12 month ******* warranty)


Question is this:

In event of my turbo failing and it not being covered by VAG UK warranty - is there a reliable aftermarket replacement turbo available - if so, from whom ?


Cheers
