Audi A6 C7.5 Start Stop Failure - 10 Days Old

[PistonTim]

Car is a 2.0 TDI 190 ultra s-tronic, since new the start stop has always seemed ultra aggressive, cutting power if you stay still for a second or more and even just ahead of coming to a stop, seems like it wants to stop all the time if you're not rolling!

This afternoon after quite a long drive the car stuttered at a roundabout, almost felt like a stall.

Then on the next roundabout with traffic light controls we were half way round in a queue and the whole car comes to a stop, with a start stop system has been deactivated warning and to manually restart the engine - err it's keyless.

A quick reboot into park and then the usual start process with the start stop manually deactivated and it drove fine the rest of the way.

Anyone else having similar issues, can't find the TT thread but wonder if it's similar?

Cannot say I have had the deactivated warning message but having owned the a6 ultra for only 3 weeks can confirm that the start stop is very very sensitive and triggers at every opportunity, its even switched off the engine whilst i have been driving slowly which I believe should only happen if your car settings are set to eco but I have mine set to dynamic and it still does it. The usual sequence of a firm push on the brakes to activate the start stop and a gentle push doesn't activate it is very hit and miss.

We have ours set to normal and it still cuts power in slow moving traffic, I can't see it does it much good to be so sensitive in our roads!

My 2015 Touareg does the same thing - start stop kicks in as you come to a stop rather than when you have stopped, the lack of power steering in a big heavy car is something which needs anticipation.

Sounds like something they may be introducing across the group - pre November Touaregs didn't behave like that.

Seems so we test drove w '64 C7 and it wasn't like it either
