A6 1.9TDI 52 REG AVANT HAVING TROUBLE WHEN TURNING AT SLOW SPEED SOUNDS LIKE TRACTOR
i have change the p/s pump, belt tensioner and the belt, and it is still the same, the belt is making more noise then the engine at tickover, lift the revs up a little and it is ok.....

;) ;) The alternator pulley clutch is seized and the belt will be jumping.The pulley is about £30 to £60 depending on the manufacturer of the alternator and you will need a 14mm spline socket to replace it(i think its 14).You can remove the alternator with out loosening the lock carrier,remove the viscous pulley and remove the alternator and remove the pulley.When they seize the pulley cant slip with the ribbed belt and the tensioner takes the strain and can snap off.

Would anyone suggest I have same problem?

To explain:

Only started this week, when starting from cold, seems the power steering has started to groan, and only when I turn the wheel. When the car warms up the groan goes away. The actual steering itself feels normal.

I've just bought a 2003 Avant 1.9 TDI and I think i may have this alternator clutch problem? I'd appreciate any help/confirmation from anyone who's experienced it...

On full lock the steering makes a loud "intermittent squeak" :confused: (not the normal squeal I've had on other cars) and I've noticed that when reversing at very low speed there is sometimes some judder through the steering. Could this be the alternator pulley clutch?

When Turning At Slow Speed Sounds Like Tractor And The Belt Slips, Once The Revs Are Up, The Engine Is As Normal.

I read somewhere else on the forum that there's a special tool required to remove the pulley. Is that the case or is the 14mm spline socket all I'll need?

Don't want to start "fiddling" until I know I have all the tools required!

Bump this thread this evening. I changed the alternator pulley on mine but can't remember now. Will check tonight for you should I remember.

If I remember correctly I used a 14mm spline tool. I had this problem on my T5 too it is really common on VAG TDIs.

Sorry Eeyore I didn't reply yesterday evening.

I indeed bought a set from Andrew Page Motors (http://www.andrewpage.com/). It is made by Laser and is an M10 spline.

Here (http://cgi.ebay.co.uk/Laser-0592-Spline-Bit-Set-3-8-6pc-M5-M6-M8-M10-M12_W0QQitemZ160293414723QQcmdZViewItem?hash=item1 60293414723&_trkparms=72%3A1301%7C39%3A1%7C66%3A2%7C65%3A12%7C 240%3A1318&_trksid=p3286.c0.m14) is a link to one on e-bay, it is exactly the same as what I bought.

Thanks very much for that Paul, I'll get one bought and order the pulley. Don't suppose you have the correct Audi part number from your invoice? I've got an AVF engine code but I guess this part will be the same?

I don't have the Audi part number because I also bought the pulley from Andrew Page. However, the part number should be 06B903119B which to my knowledge costs £59.46 plus VAT.

Finally planning to replace the alternator pulley on my A6 next weekend but I've just had a look and access looks pretty tight! I assume the alternator will have to come off...?

Has anyone done a short "how to" for this job?

The pulley on my alternator is quite small (3" or so) - is that the part I need?

Thanks!

Yes it is a male splined adapter the locates in the pulley and an allen key passes through the whole in the centre and undoes the retaining bolt. Audi refer to this tool as '3400' Regards Peter

This could just be the pump belt that is loose. If the clutch pulley sprag clutch has failed the serpentine belt will flap quite a lot at tick over. You can also check the clutch, as your engine code implies you do have one, by inserting a soft object like a lolly pop stick/ paint mixer through the air vents and try turning the alternator fan clockwise. Regards Peter

I removed the alternator. It may not have been neccessary as Peter says but it looked easy enough to do. Eeyore it is indeed what you describe.

Replaced it and all was well. Before Crasher alerted me to this problem I was getting ready to change the catalytic converter believe it or not because of the noise. When I realised it was worse when steering was applied I was preparing to change the power steering fluid and possibly the pump! Thank heavens for this forum and its fab members!

Aargh! Just called the local GSF motor factor and they say they don't list a pulley for my car. They've asked me for a INA number??

Don't really want to take the alternator off without having the new part to hand!

18-11-2008, 02:16 PM
Is there an Andrew Page near you?

I can't understand GSF not having the part... Andrew Page told me they sell these weekly!

No, I think they're a Northern company. Maybe I'll try the dealer and another motor factor when I have time to ring round.

That's as dear as Audi!!!!! :aargh4:

You may as well go and get the genuine part...

They can also be had for about ~£40 at Andrew Page Motors (I think they're a sponsor on here).

Yes the M10 spline tool and part look right, but they are both cheaper elsewhere.

If I remember correctly I got a 5 piece Laser spline tool set from Andrew Page for ~£10, and the pulley at ~£40.

It's up to you how you spend your money, but the above 2 are overpriced. ;)

Just have to work out if Andrew Page will send to Ireland!

Sorry everyone. I'm all questions. I promise to start posting some answers soon.

I read that the tool reqd for this job is the 3400, but this one seems to be numbered the 3307, and is listed as being for the Bosch (not the Valeo).

http://cgi.ebay.co.uk/Laser-3307-Alternator-Tool-M10-Spline-1-2-Drive_W0QQitemZ260359242301QQcmdZViewItemQQptZUK_H and_Tools_Equipment?hash=item260359242301&_trksid=p3286.c0.m14&_trkparms=72:1683|66:2|65:12|39:1|240:1318

I reckon this is the right tool...

paul b
10-03-2009, 03:25 PM
Looks like its the same.

I think it will do, I wasn't aware that they're different for Bosch and Valeo alternators, I just knew an M10 spline was needed.

I've found now that it is not the alternator pulley that is faulty on my car, but rather the tensioner pulley.

I've been advised by the Audi dealer in Belfast that the whole tensioner should be replaced - rather than just the pulley. They reckon the tensioner can break? Can anyone back that up? I don't want to spend 100£ extra that I don;t have to.

I don't want to skimp though, on 100£, and then have to pull the old girl apart a second time, just to replace the tensioner!

Thanks

Hi. i've got a 2000 Bora tdi, i also seem to have the same Clutch Pulley Fault, how much will it cost at a local garage???

farmamick
27-03-2009, 08:09 PM
Alternator pulley - £70
tensioner pulley and tensioner - £200
belt - £15

These are genuine Audi prices. I wasn't willing to go to the pain of pulling it all apart a second time, because I used shoddy parts. I figures I'm saving money by doing it myself - I'll spend a bit extra, and use all Audi parts.

I haven;t done the job yet, so I don;t know how long it takes - so can't comment on how much a garage should charge.

Special tools you will need are the alternator pulley tool (Lazer 3307 "alternator tool" - M10 spline, 1/2" drive).

I don't know about access to the bits on the Bora - for the A6, I have to pull the front off/forward, so there's a special pair of bolts that keep it all together, just moved forward.

Come to think of it, if you were going to all that hassle, think about replacing the cam belt and water pump, and air con belts as well - depending on the mileage and how long its been since you did the cam belt.

Hi, I have a 2003 plate passat 1.9tdi and had the same power steering noise on full lock. Sounded bad, very embarrasing especially in car parks, like a previous user said almost like a tractor. Unfortunately I wasted hundreds by having the ps belt, the tensioner and the belldamper changed and it turned out that the alternator pulley was siezed, please change this first if you have a b5.5 with this problem.
Thanks

Hi. can anyone help me!!

my 2000 Bora tdi has recently been showing a Alternator Workshop fault while i drive and the battery keeps flashing!! and another thing my power steering has gone stiff when turning at slow speed or at idling speed!!

Could anyone help me with this!!

Cheers

Aside from Andrew Page or Audi, does anyone know where I can get the alternator pulley from?

GSF and Euro car parts don't list them and neither does Camberley Auto Factors who are our local motor factor. I can't believe they are so difficult to find!

So far I've been quoted £65.67 inc vat from Audi, or there's one on ebay at £61.

I got ripped off by Andrew Page for my alternator pulley, it cost about £60 from them. That's way too expensive considering its not even a genuine part!

I am a lost customer of Andrew Page. They pulled the same stunt a few months later for a Skoda head gasket I needed - dearer than the dealer!

Having seen the prices you have been quoted, it makes perfect sense to go to the Audi dealer. This way, you have a part with a guarantee and it will last as long as the one you're taking off. :)

Do you have the M10 spline tool to remove it?

eeyore
25-08-2009, 12:28 PM
I've just ordered the tool off ebay for £14. Bit of a pain as I may never use it again but still cheaper than paying someone else to do the job :approve:

OK guys, finally tackled this job today along with a service and the result is non clanky power steering and quieter, less rattly idle :D Thanks for all the advice given here in my run up to actually getting the spanners out!

Only problem was I couldn't get the pulley tightened to the recommended 80Nm so it's on as tight as it'd damn well go!

Servicing was fairly easy, apart from way too much scrabbling around on the floor trying to get the undertrays off (to get to the sump plug) battling rusty fixings and bolts you can barely see let alone reach! Anyway, all back on now and seem secure...

Next job - aircon fan, which only runs if you hit it :( (then re gas) and a recon kit for the rear wash wipe.

PS: Finally opted for the genuine alternator pulley from Audi at £65.67 inc.
