Hi guys, Can anybody help?? I have a 3.0tdi which has started going into limp mode (flashing glow plug light) usually when I am quite heavy on gas on the motorway and lift off at 80+ if you switch off ignition and back on fault is cleared and power is restored. Fault codes showing are
P3348 - Control Circuit for controller for turbo charger
I have had the actuator control box replaced and calibrated at Audi main dealer
P0235 - Regulation range not reached
Audi stealership are telling me a new turbo is needed £1750 - I don't think so when it drives perfectly 98% of the time!! I think this is overboost code so I have had the turbo removed and mechanically cleaned suspecting sticky vanes and not fancying the Mr Muscle idea. This was done by R-tech who said that the VVT needle was moving freely before they did the work and did not think it was worth doing. I still had it done to rule it out!
Car still does exactly the same thing when I welly it
Its a s line A4 quattro tip.
Please someone tell me you know what I can do now?
