right where do I start I have a 2.5V6 tdi superb, since owning it the emiisions workshoplight would come on but never effected the performance, changed the temp sensor and seems to have fixed that issue. however it keeps going into limp home mode, I thought it was to do with waiting for the glowplug light to come off so I have been patient and all was well, until last week. it now goes into limp home mode, but doesn't show the engine chacklight until I restasrt the car, I just get emissions workshop and loose power. 3 fault codes show up, throttle potentiometer signal low, egr something or other and a boost one alos. Its worth yelling you as well that I think the brakes feel spongy when this happens also, i'm thinking vacumm pump but not 100% sure. this ia becoming a real pain as it also won't let me clear the codes, waiting 10 minutes for it to cool down word previously. any asistance wouls be greatful as if I take it to the dealer i'm going to spend loads on daignostics. I'm hoping rotodiesel can help from what i've seen the guys a bit of a legend. Many thanks Grant

changed temperature sensor, other than that its been tested by autoelectrician/diagnostic guy, funny thing is the faults were cleared and no can't get it to do it again, garage say it kept doing it when warm, i've been driving round for an hour and all OK??
