I recently bought a A4 2.0 TDi and on my first long distance trip the glow plug light on the dashboard came on and the vehicle lost power completely. I pulled over and switched the vehicle off, waited for a while and then turned it on again. The light went out and I had my power back, but the cruise control didn't work from the point onwards. Did any other members experienced the same and what can the possible causes be? Turbo and injectors has already been replaced. No smoke that I could see. I will take it tomorrow for a diagnostic, but would appreciate if there are members with some advise. Thanks a million.
