Gearbox/haldex oil changing or not?

Hi all been a while since last post....

my a6 c6 4f2 s-line 3.0 v6 tdi auto has just hit 80k miles only owned abt 18 months and all of sudden im thinking of changing transmission fluid and haldex fluid

I have phoned audi and they told me that it doesnt get changed ever as they are sealed for life units and when they entered my reg there was no option to change gearbox oil or haldex oil

is this the case that I dont have to do this or are they wrong? my service book states 'changing oil (ATF) in multitronic gearbox all audi models every 38k miles', does my model apply to this?

I really would like to find as I have an opportunity to do this now, if not, i wont

Cheers for your help

According to Audi the tiptronic box it's sealed for life, according to ZF who make the tranny it should be an 80k change and 50k thereafter. Audi weirdly only warranty the box for 80k miles?

I know who I believe! :biglaugh:

It is not the same as a multitronic change and a lot more expensive and fiddly so best left to a specialist

I paid Bristol Transmissions to do mine at 90k in 2013 and the total was £276 inc aftermarket fluid/filter and VAT, using Audi originals it's about £100 more expensive. You can insist Audi do it and I believe it costs close to £600+VAT

As to the Haldex system, something that I've considered, Audi I believe charge £69 which is a good price considering the supply the fluid and filter(?) and a special tool may be needed which requires it to be lifted quite high.

Definitely change them , the VAG group are full of bull , but then we know that .

Hi

All the Quattros use the Tiptronic box so you can ignore anything that refers to Multitronic. I'd still have it changed though despite anyone claiming sealed for life.

Also and please don't think I'm being pedantic but the inline engines such as the V6 use a Torsen differential not a Haldex so again please be careful what notice you take of anything that mentions service intervals on these.

Cheers

Thanks Markaz,

This made for a good read:

How does the Quattro system work?

Thanks Mark - interesting read! Out of interest what gains did the Alientech remap give?

I went for the eco remap so SoTP dyno circa 12% (28BHP) weirdly when I told my insurance company (Tesco) they advised that there would be no additional premium.

I have achieved 920 miles on a brimmed tank in a fully laden car so calculate that's 50mpg, exceptional trip as Somerset to Glasgow and return non-stop (2 x 400) in the wee small hours is not what most people will get, that said I can get 40mpg after 8 miles and close to 50 after 20 miles in normal M'way driving.

Appreciate there's not much traffic down here, plus I choose my journey times carefully having to factor in holiday-maker changeover times on Sat/Sun when I'll simply not go out unless an emergency :)

The remap coupled with a straight through stainless zaust and no back boxes means it drives like it used to in 'S' mode, and now S mode is pretty rapid :biglaugh:

Thanks Mark. I'm looking at a Quantum remap at the minute. They've quoted £200 for the usual extra 35hp and 65 NM etc. I've been told they're ex Superchips people who branched out on their own.

Bet your exhaust sounds ace!

PS what's a Pogo Alert+ ?

2 days after buying the car in 2012 I did my first long M'way drive of 185 miles as friend had got me tickets for the Olympics.

Unlike my profile pic car which is modded/decatted with a straight through perf exhaust, the Audi is completely quiet at 70.

As I didn't know how to use the cruise or speed limiter I was stopped on the M4 doing 104...just keeping up with traffic :(

6 points and £125 fine later I had this fitted, so not only does it give you warnings of any lasers and cameras but also gives your average speed through roadworks, which is essential to ensure no more points. Can't find a demo on youtube, but this is what it looks like:

A case of RTFM before driving :Blush2:

Thanks (again). Got to admit coming from a Honda CRV the A6 has caught me out a few times with how fast I'm going. Out of interest did you hardwire your Pogo in or use the socket? Looking at a dash cam but don't want wires running everywhere!

Hardwired, pic attached, ball joint a little loose so has cooking foil inserted for better grip

Attachment 28791

Thanks Mark. Can you let me know where you picked up the supply from please?

Professionally installed, so no idea.

OK thanks Mark.

OP apologies for hijacking your post!

Adding to this, in the sense how OP is wishing to do a fuller oil change.

The Tiptronic box has 3 chambers for oil.

The main which is discussed a lot, then you have the front drive chamber and rear output chamber on the tranny.

The the rear final drive unit has it's own oil.

VAG SSPs have this info, google SSP 325 , view page 82 for chamber info, some tech specs on page 80.

The real final drive is covered in another SSP but if you google A8 parts d3 tech dump first hit takes you to a thread, scroll up and you'll find 2 interesting files.

38-Service Manual Rear final drive 01R
45-Servicing automatic gearbox 09L four-wheel drive

Plus google for ECS tuning tiptronic reveals a nice pdf (5th hit) and there are also some ZF pdfs floating about on net and threads here.

Thanks for all your help, I spoke to Audi technical (not a dealer) today and they told me and I quote 'I do not need a transmission fluid change,
Haldex oil change or filter change. This is a fully automatic gearbox which doesn't require this procedure therefore it isn't an option for audi to carry out on my specific model'

So with that, I should leave well alone!?

ps. thanks to gupsterg for the literature on this. I assume mine is the 09L gearbox?

Mertz, perhaps you should have spoken to your Audi Tech BEFORE posting:confused:

I know that at 78k miles my tranny fluid was black and smelly and the change improved my shifting.

Good luck!

ZF recommends to change the oil/filter no matter if Audi say it's "sealed for life". It's been discussed already on several threads.

Personally I'd like to go by ZF recommendations.

I can see though how it can be hard to get the change done.

Main dealers mainly speaking are not gonna touch this exercise IMO.

I can also see why many indies would also not be open to the idea, even the very famous VAG indie I went to when getting the chains done really wasn't that open to the idea.

Tranny specialists on the other hand would be IMO.

The main thing any of the main / indie VAG places are gonna impress upon an enquirer is "If it ain't broke don't try to fix it". Which to an extent is good advice but I also think just like an oil change to the engine is essential servicing it must be for the trannys health!?

I also think to really do this technically by the book an adaptation drive is essential. Link:- Tiptronic oil change ! - Page 2

Now if we take sourcing oil for rear output for example highlighted in these 2 posts, Link 1 & Link 2 (more info view page 14 of SSP 385 , use google to gain, 1st hit) and doing the job plus adaptation drive. I think a lot of main / indie VAG places a) don't have experience thus don't want to do job wrongly b) don't want comebacks if tranny perform worse after the job.

I can't remember if the post I read was concerning the earlier Tiptronic tranny ie in cars gen before (A6/C5) but someone with more experience stated the only thing Tiptronic suffers from in the main is lack of oil servicing.

Due to the mini fortune my car swallowed in early ownership I'm not going all out on servicing tranny, so I guess perhaps each to their own? dependent upon how they envisage their current and future ownership of car?
