H every iMovie got a a3 2.0 fsi. Bought it about 6 weeks ago. Now the engine management light has come on so took it back it back to the garage. He run the diagnosis and confirmed its the nox sensor..
now he's saying run the car on super unleaded for 3 months and the fault will clear itself. He has been told this by Audi uk!
I've been told by a mechanic I know we'll that when its gone it gone.
Who do I believe. Your help would be appreciated
