I had a slight panic moment this morning as I thought about the new E10 unleaded. I have a 55 reg A3 8P with 1.6 FSI and the gov website stated that the 2004 1.6 FSI was not compatible with the new fuels. Always best to check with Audi though. Mines fine as it’s got the 2006 engine after they checked the reg.
