I'm new on this forum and have a A3 2.0 TDI 2009 year Sportback with the common rail diesel engine.
Whilst driving at higher speeds on the motorway for over a few miles my Glow plug light starts flashing,
I've had the cat plugged in and have been given a error code of P0299 with message of TURBO UNDER BOOST, Permanent.
Could any one please advise what I'm up against ? Some maybe Turbo others the Actuator and a few saying it could be the Turbo boost sensor?
Are there any good specialists in or around the Birmingham area please?
