2021 50 TDI Tiptronic Behaviour- slipping?

[St3veM]

I found the same problem with mine from new in 2020, and is no better 4 years later. It's like the torque converter won't fully lock-up from standstill or low speed in 1st & 2nd gear until you've built more speed. The harder you try and accelerate the more pronounced it is, unless you really nail it. I thinks it's actaully worse in Sport mode! From what I understand, Audi programme the gearbox (ZF 8 speed OD5) like this as a torque limiter. As far as I know, you can only get over this with an aftermarket TCU remap, such as the ones that Darkside Developments do. As there's no 'official' solution, I'm going to get this done as I've decided to hang on to the car long term. Has anyone else tried a remap?

That’s a good way of putting it. I’d also contacted Darkside but mine was a lease/in warranty so didn’t want to touch it to that extent.

Not a problem now as I’ve got shot and have a Q8 etron

Excellent choice, problem solved�� As I won mine it's not a problem to tune it.��

tsteviejames - your description is spot on! I would be really interested to hear how you get on with Darkside Developments. Having exactly the same issue. Had both main dealer and a really good independent look over the car and both saying no software updates available, no error codes, no signs of mechanical issues. So your explanation re torque limiter makes complete sense.

Yep, tbf the order went in, in Feb and delivery in July way before all that kicked up

Just chopped it in early and got rid as was really really ****** off with the gearbox and Audi’s attitude towards it. Shame as it was an amazing car, comfortable and brilliant for long journeys - just an absolute pig at slow speeds.
