My AUQ engine has recently started to overfuel.
So far the lambda sensor/MAF/Injectors/FPR have all been changed but still overfuels.
Did a smoke test and had a boost leak from the intercooler MAP sensor but this is now fixed.
The car is on a standard oem map but the mechanic could not adjust the fuelling to stop it from overfuelling.
Been told that the head will have to come off for further investigation.
Any ideas what it could be? no fault codes showing either
