Audi A6 Saloon, 2007 3.0TDi Tiptronic Le Mans.. Not happy.
Discussion
Hi all, my first post and looking for some clarity if I could please.
I bought a 2007 (57 reg) Le Mans edition A6 with 93k, 3 days ago.. It has a FSH, mainly all indi (but I dont mind that).
Firstly the fuel gauge stopped working right away, so it has gone back in to the dealer (local trader not Audi) - to get that rectified..
The biggest issue or... maybe its a non-issue is with the gearbox, it shifts ok and pulls alright but it feels like it is slipping as its gaining speed.
Is this the torque converter doing it's thing? It's like it will accelerate and the MPH will be piling on but the rev's aren't going up as it does so and seems to 'stick' at a certain revs then it feels like it catches and then the revs go round as 'normal'.. This is the first true torque converter box i've had.
It feels as though it is feeding the power through then when it's happy it lets the revs go... Unless the box requires a service, new oil etc?
There are a few niggles and so far the trader seems ok, I have 6 months warranty too but don't want all this after this short time.
The MPG seems fitting with what i've read, round town and on a run. (25-30 and 35-40)...
Thanks.

I have had a 2010 A6 tip for a few weeks and posted about a slight gearbox bump in another thread.
A few things I have learnt coming from a DSG is that it will slip the torque convertor a fair bit under acceleration before it then locks the TC up. This does sometimes feel like an extra gear change as the revs drop. I beleive it will lock the TC more aggressively in sport or manual mode.
Speaking to a specialist the gearbox does a fair bit of rolling adaptations to suit driving style etc, but can be thrown if it is left standing for a long time or by other engine faults like MAF etc. There are other more fundamental adaptations that can be performed by a techincian that effect clutch pressures and other things, but if these are done wrong it will cause premature wear.
Audi will tell you that the oil is sealed for life, however ZF who make the gearbox recommend changes every 50-70k. I am currently looking into this with a specialist as the oil is expensive (£35 per/lit) and requires special extraction to get all the old stuff out.
In my experience it has taken me a few weeks to get used to it and some of my issues seem to be lessening either through it or me learning.

Changing gearbox oil can cause issues, on balance I decided not to do mine. No issues up to 118k miles when I sold it.A few things I have learnt coming from a DSG is that it will slip the torque convertor a fair bit under acceleration before it then locks the TC up.

The adaptive gearbox map can get confused after lots of town driving and make the car feel down on power. Stick it in sport mode and back to normal on the open road and it should be ok

they certainly can. Mine was like a slug after two weeks parked up.Under acceleration, you'll tend to find the car will sit at a particular rpm, and just accelerate until the car catches up with the rpm\gear.
If in doubt, try the car in sport mode, that should be very quick reacting to throttle and holds onto the gears far longer.
Here's am description of how the gearbox adaptation\coding works (D3 A8 is very similar to A6 C6)
