2.0 miggy n reg auto
this car is now starting to cause me serious headaches can some body please take the hell out of help and tell me how to rectify these codes

13,71,73,and last but not least 92

The answer is in one of this lot.....

Prey tell, what are the symptoms?

The codes you have listed can't be correct for a 2.0 litre, they should begin with ten flashes (i.e a zero).  Do the paperclip test and flash the codes then post your results again.

Count 10 flashes of the EML as a 0.  Here's an example...

...If it has 10 flashes, pause, 3 flashes, pause, 4 flashes, pause, 10 flashes pause - the code would be 0340 (camshaft sensor).

Don't buy a post 2001 Volvo and certainly not a T4 or T5, as that is what the wife has got and we are going to be stung £400+ for road tax.

Apologies - obviously a different ECU to mine.  I'd try a new air flow meter.  Get it out the scrappys though.  Mighty expensive from vauxhall.  Are you getting poor idle?

As 'Marks DTM Calib' said, it would help if 'Polti' could give us
a vague inkling of symptoms he is experiencing.

Off the top of my head, looking blind at that list of codes,
I would tend to start with the camshaft sensor, as if that is
faulty, it can cause spurious other codes to pop up when it
confuses the ECU's AND/OR gates.

Lol....check the inlet for air leaks.....particulalrly the rubber pipe that connects to the throttle body where it goes through a 90 deg bend.
