Hello all, looking for some advice here. Just picked up an Audi A2, within 5 minutes of driving away the engine started stumbling on acceleration, particularly half throttle scenarios and on came the engine light. I gave it a scan and got EGR excessive flow and Fuel trim system too lean fault codes. Anyway, I drove it again and the hesitation/stumbling has got far worse, the revs keep jumping up and down. I scanned it again, still have the two above codes and now I have two fuel injector short to plus fault codes. I have included a picture of the latest scan below.
I have noticed the EGR valve is sucking through it's vent pipe so I assume first thing to do is to change that and work from there. I can see how this could result in a fuel system too lean as well. However, does anyone have any thoughts on the short to plus fuel injectors? Unless the injectors are overworking to compensate for the extra air I can't see how the two could be linked? Any thoughts as to what other issues could be around here? As I say I'm trying to get the EGR swapped asap.
Any help would be much appreciated, cheers!
