Hi everyone. Need some advise as I don't have much experience with TDI's I own an A6 C7 2.0 tdi, been faultless the first 6months but last couple I've had a Throttle Position Fault coming on and off randomly. Car went to the garage earlier and they've diagnosed it as faulty EGR, priced at £600 to replace! Anyone else experience similar issues? Worth cleaning rather than replacing? Can't seem to find much info on the c7 platform only the c6
