2016 Audi S6-Stop/Start not working

[chudiddy]

Not that I use it very much, in fact i've had it turned off for the better part of the year but I decided to give it a try and for some reason it will not activate. I get the symbol on the DIS but it has a line through it. I understand that there are certain conditions where it won't work but I have tried it for the past few days and it just won't activate. I will say that it has worked before, I just can't remember if the last time I used it was before I got tuned which I think is the case.

I am wondering if the APR tune deactivates the stop/start feature. Can anyone confirm this at all? Am I missing something, a setting, vagcom, etc?

Thanks in advance.

I haven't heard anyone else say that a tune disabled start/stop. If you look at the efficiency meter in the DIS it lists the reasons for not activating start/stop (may be a my16 feature). The main reason is A/C running and it's reluctant if you're not in D mode. I did hear of one person that had a faulty module causing this.

I once had this on my 2016 I just checked for fault codes cleared them and it came back.

I turned the start/stop feature off the day I got the car and never looked back. After reading your post, I thought I'd give it another try since I recently got stage 1 APR ECU/TCU software. I activated it while standing at a red light and the engine remained on showing the icon under the D1 display with a line through it. However, when I stopped in my driveway two minutes later the engine turned off. So my start/stop feature still works after the APR stage 1 upgrade. However, I have only tried it in D during the last two minutes of my commute so I'm not sure if S would make a difference.

How do we deactivate it permanently? It's the most annoying feature I've had on any car. Absolutely hate it.

For the S6 the selection you make using the console button is memorized. This may also be the case for the 2.0T A6 since it seemed to be that way on the loaner I once had. For the 3.0T A6 you need VCDS to deactivate since it will default to "on" every time you start you engine. Below are the instructions I copied from the thread in this forum.

Disable/memorize/invert Start & Stop:

- module 09-Cent. Elec.
- enter Security Code (20113)
- Adaptation on Channel 34:
subtract 4 to the value --> Start&Stop always disabled
add 32 to the value --> memorize last status (the Start & Stop status at engine startup will be the one at last engine shutdown)
- test & save
In addition of these values, if you add 64 to the value, the Start & Stop button light will be reversed: off if Start & Stop is disabled, and on if Start & Stop is enabled
