Startprobleme - Vorglühkontrolle geht nicht aus | Posts 16+

Dein AUto sollte eine WFS haben, die diagnosefähig ist. Opening remarks, 25th.

Okay, so, if the WFS (presumably a vehicle system) fails to start the engine, and it either starts and immediately shuts off, or shuts off while driving, then there's a high probability that both the WFS and the engine have stored error codes. In the engine's error codes, you would likely find something like 'Engine control unit locked / intermittent.'

You might want to check if your pipes are...
a) It might be located at the bottom of the throttle position sensor, where it could be incorrectly positioned or possibly corroded (both the connector and the sensor itself).

b) Try removing the wiring harness in the engine compartment and have your powertrain checked by the engine control unit (ECU). A friend had a similar problem where the wiring harness wasn't properly secured, and over time, the wiper linkage rubbed against one or two of the wires.
