Hi !
During the last two weeks, the family has been on a car holiday in Europe.
We have driven about 8000 Km and before departure I checked error codes, but there were none.
Now I checked error codes again and now there are these:
Can someone explain in understandable terms what the problem is ?
No MIL.

Car: Audi A4 1.8T Avant Quattro ( "B6/B7" )
Engine code: BFB
