My Passat has a strange fault, please give me some advice!

In case of sudden flameout, it is best to check the high-voltage line (i.e. ignition module) first. Aging or internal fracture of the line may lead to poor contact and accidental fire.

In addition, only one crankshaft speed position sensor and one camshaft position sensor affect the ignition time. Go to the 4S shop to test these parameters while driving to see if they are consistent with the manual.

In addition, check the throttle position sensor, oil pipe and oil pressure.

Just turn off the fire, as long as the oil supply and gas supply are lit, it will definitely ignite. Check these three pieces in turn. As long as the intake pipe is not blocked, the fuel injector can burn as long as it injects fuel (here, consider checking the nozzle) for 6- 10 degrees.
