Hopefully someone can help me, my 2003 A4 2.5TDi suddenly for no reason died on me while commuting at 40mph today. I was driving in traffic and suddenly the Traction Control light came on and the throttle was totally unresponsive. I pulled over to find that the Glow Plug light was flashing at me also, and the funny thing was that the engine was running, but nothing at all happened when I pressed the accelerator pedal. I plugged my OBD code reader in (Handy thing to keep in glovebox) and it reported NO DEFECT Codes. I switched the engine & ignition off for for about a minute and then resterted her and all was reset and back to normal. The engine sound was normal so I pulled away thinking it must have been some sort of electrical glitch, perhaps in the fly by wire throttle system.
About 1/2 mile down the road it did the same thing again. I reset the ignition so I could at least get the car home, and that is where I'm at just now. Please, please, please can anyone help me out here as I need my car on a daily basis. Any advice would be gratefully received.
