Vagcom reckons my car is running rich. 17545 - Fuel Trim: Bank 1 (Add): System too Rich P1137 - 35-00 - - to be precise. Its also complaining that there is a pressure drop between turbo and throttle valve. I've already replaced the DV with a forge one. I guess its possible the pipe is screwed? Would this error also cause the system too rich one? Got an MOT due by end of month and not liking what this might do to the emissions. No other errors found. The engine management light came on which is why I did the vagcom check. Cleared the codes and its not come back on yet. Everytime I fix one thing on this car, another problem appears. I expect there to be an error code of 'car on fire' popping up soon!
