Hi,
I am having a few issues with my 2019 Audi A6 Avant. When starting the car it sounds like it is struggling to start up and will sometimes come up with a start/stop fault warning light, followed by drive system fault contact workshop. This is also sometimes followed by various other warning lights such as the auto beam assist, audi pre sense, washer fluid. The car also cuts out of cruise control if being used longer than 40/50 minutes then goes into D mode instead of a gear when taking my foot off the accelerator at any time, the cruise control will start working again if the car is restarted.
I have had the car into Audi regarding all these issues and they couldn't find any fault so cleared the stored codes and then driving long distance the next day the drive system fault came on again, so it is booked back in for 16th April. I am just wondering if anyone has had any similar issues and could shed some light on what it may be since Audi themselves cannot find anything wrong and charge £150 fee for every diagnostic issue that is investigated and there is several.
This morning the car failed to start this time and came up with the drive system fault contact workshop as pictured. Putting the engine off and starting it again seemed to work.
Any help would be very much appreciated! Thank you in advance.
