Did you manage to find out what the issue was? I’ve bought a 2018 A3 2.0 TDI and noticed the radiator fan comes on sometimes even when car hasn’t been turned on for hours. Killed the battery once. Now today the engine management light has come on following the fan coming on earlier after being off for 6 hours. Bought it just over a month ago, will call the dealer in the morning but I’m not holding my breath!
