Gearbox Software

[cjmcb]

Hi all,

I have been having a few issues with the gearbox in my 3.0 biTDi; its now 2.5 years and 22k old- the first was at 6 months old and the car would attempt to engage 7th 8th while still driving in 8th gear. This was fixed by a remap of the gearbox ECU. Then about 6 weeks ago I had it "bang" down through the gears from 5/4/3, again the gearbox ECU was remapped with a software update; the car now seems o hold 7th gear for an age, 45-70mph under super gentle acceleration and when it does engage 8th it is super quick want to change back to 7th and then rev faster. I have been overridding this with the paddles but it is now beginning to annoy me as accelerating by 2mph should not require a downchange and flare of revs??

Does anyone have any suggestions or is this normal? Thanks.

Are you remapping as in aftermarket remap or Audi doing a software update?

[cjmcb]

Audi software update as car is still under warranty.

I second A6S, I'm having issues with my gearbox as well.

Similar to mine or different?

It just shudders now and then. I'm getting mixed opinions of that it needs to be serviced or software update. Phoned Audi UK and they say it's sealed for life and does not need an oil change. I'm so confused man lol

No this does not sound like normal behaviour.

The only complaint I have for the BiTdi ZF box is that it (in my car) occasionally gets confused when you are in 3rd gear and off throttle coasting to a junction (or braking gently) and then you turn in and give it a little throttle - just a moderate amount. Suddenly it decides it wants 2nd and can be quite a clunky down change, almost a "bang". Does not always do it - in fact rarely does it - but it's annoying.

Now I did mention this to my Audi dealer and asked about gearbox firmware updates and the said there were none and that they could not do them because the vehicle is certified for MPG etc with the factory shipped firmware. Credible enough (i.e. if they remapped the engine it would not comply with the factory MPG and probably emissions stats)... but seems like I smell a rat if cjmcb has has a new set of firmware loaded.
@cjmcb - are you sure they actually loaded new firmware or did they just reset the "learning" on the box? It is supposed to learn your driving style and adapt ...

The gearbox is due an oil change at around 60k miles (this is from the ZF website recommendation). You have an authorised ZF transmission specialist near you in Glasgow. Might be worth giving him a call and see if they have the gear to fault read the box. I would imagine they do as they have the software for the C6. First call should be Audi though and a reset might be all that's required.

Automatic and Manual Transmission Repair Mackie know more about zf boxes than all the Audi dealer in the UK put together, and I cannot recommend them enough. However as your car is under warranty then just let Audi sort the problem out, they will most likely just replace the box if they cannot fix the fault.

i think Audi called it a TP Update when they did mine and B5NUT is spot on as they worked wonders on the old A4
