hi,
in my a4 cabrio b7 2.0 tdi i have some problem sometimes in starting.
In poor words:

1)turnk key in half position
2)engine checking light did not go up
3)esp and abs light permanently goes up
4)it's impossible to start engine...

why???

Sounds like an electrical issue. There may be a communication failure between engine control module or abs module. You need to scan your engine control module(ECU/ECM) for trouble codes. That will give you a place to start looking.
