Default Did you ever fix this issue?

I have been having the same issue in my 07 A4. Changed plugs coils and still same misfire in 3.

Any change audi dealer download codes that screw up cars? My A4 was running fine when I took it in for a recall fix and then nothing but issues. Same for my 07 Q7. Ran great. Took it in and 3 days later 4 diff Ent codes started pooping up. Can’t figure them out.

Fyi to all DONT BUY A Q7 w 4.8 EVER!!! $7000 at 100k miles to replace timing belt. Unbelievable!!!
