Recently i have been having this problem with my Audi A4 1.9 TDI B6 AVB.
Randomly the ESP light would come on and the squiggly Glow Plug light would keep on flashing. The car does not move at all but the engine is still on and if i press the gas pedal nothing happens. Also its stuck on 1200 revs. After switching the car off and switching it on again after 5 minutes .. the car drove for a bit and then the same problem happened again ..??
Whats the cause to this problem?
