My 1999 A3 1.6 is giving me a lot of grief! It is hunting on idle (which i hear is common with this engine) it also has a slight misfire, mainly when under load.
i have noticed it also seems to be using quite a bit of water.
These problems seem to be why it has failed the MOT on emissions. Does anyone have any ideas what could be the problem/had any similar issues themselves?
Could it be the Lambda?
Any help would be awesome, thanks guys
