Hi Guys, Need Help. My 2013 A3 had the 'gearbox mall function-You can continue to drive' message popped up last week. Today it came again and the car wont move after putting in drive mode. It can reverse but wont drive ahead. I also noticed the oil leakage under the bonnet. Booked diagnostic with Audi Melbourne on Monday .Has anyone else experienced the same and what could have gone wrong?
