Just an update for anyone who cares to know more. A day after the above post the check engine light came on and after being told it was an exhaust sensor and having that replaced by the dealer the same issue occurred, the car has been back with the dealer and has now been diagnosed with a faulty camshift actuator (hence the check engine light). Apparently as this has an effect on the timing of the motor the ACC and Start Stop Systems can't work effectively hence the error. Searching around this seems to be quite common on the EA888 Engine. I now feel comfortable that the real error has been detected and fixed.

No not as yet, just researching what others have used and feedback good and bad. BTW yours look great, similar look to what I'm working towards.

Hi All, Looking for some information from those more experienced than me. So I picked up my new used 2016 S3 206TSI Estate/Wagon yesterday and everything was going well until I engaged the ACC. After only a few km it came up with an ACC error and switched off then displayed a Start/Stop System error. Any idea what might be causing this. I've just come from a 2016 Golf GTI 40 year (Clubsport) and the ACC would occasionally be unavailable but then come back on a short time later with no need for intervention but this is different. If I turn the car off then on again it resets but then the same issue just occurs again a short time later. Car is still under warranty so will be taking back to the dealer, but not the start I was looking for.
