On my way home last night my A3 2.0TDI went into limp mode. I put the car under load in 3rd gear and when it reached appx 3k revs all power was lost and drove really slow. I got to a set of traffic lights, turned car off, waited 10 seconds and re-started it and all was back to normal. Anyway, having read thru various forums im being lead to beleave that now I should have a fault logged that can now be viewed by diagnostics. Ive also read that it can be few different things from leaking pipes to sticking vanes on the turbo. I have nothced the past few months the turbo whistles a bit more in lower gears, and maybe the car does feel a little slower, but nothing too drastic. My car has covered 51000 miles, its a 140bhp mapped by custom code stage 2 and has a green panel filter and Milltek turbo back exhaust. Theres no plooms of smoke from the car. Im thinking of getting the turbo vanes cleaned by getting one of them turbo cleaning kits. Anyone else have any suggestions?
