Hi guys hope you can help??
Installed my decat pipe to my A4 2.0tfsu quattro spec ed.
After3 days of nice sound and a much more responsive drive,
The engine warning light has come on. Is this something to worrie about?
Is there a way round this?? Or shall I just put the cat bk on?
As I don't want to damage anything. But it was a tw*t to fit lol
And wanted to remap after I put a front mount on her.
Any help would be brill
