Thanks for the replies, My problem is my car is running a p8 ecu which is in limp mode. I've now replaced crank,phase, air and water temp sensors, tried another map sensor, set tps and base idle and still have the fault.
Om going to try to reset the ecu again as this may be the problem. When I try to do the reset procedure I don't get the very quick clicks as I'd expect even when being done on a standard chip.
Any ideas on anything else it could be ?
cheers.
