Well I had to leave my car at the dealer today cause they are having a hard time diagnosing a misfire issue with #2 cylinder.
All the obvious has been done.
Plugs all new.
They replaced the injector and swapped coils around and the issues still resided at #2 cylinder.
They are also seeing vacuum issue. When they pull the oil cap the enging should kind of fall on its face and it dosent at all....????
Car is a A4
2.0T with 46,000 miles,
car has a FORGE BOV and a intake that is it for aftermarket parts.
They say there is no carbon build up and all four cylinders have been tested for leakdown and compression...
Any suggestions, I know they are going to blame everything on the BOV and intake....
