A colleague's 08 2.0tdi is the problem.
Sometimes when she puts in the key if fails to start;does doesn't even turnover and the engine management light comes on.
Take the key out and in again and it usually starts.
Sometimes you don't need to take the key out;the light goes out and it starts on its own.

She got someone to scan it but she didn't have the code when talking to me.
The only info she had was it said bank 1 coagulation.

Any ideas what the problem is?
