Vehicle data:

Passat 3B.
Year of construction: 1998.
Engine: AFN
Mileage: 255,000 km



Hello everyone!

'Something very strange happened to me the day before yesterday! While turning at an intersection, I accidentally shifted into the wrong gear and almost stalled the engine.'
The electronics tried to compensate, which is normal. However, instead of settling at 960 RPM, the engine then idled at 1,500 RPM.
This condition could not be resolved by simply re-engaging (or activating) the system; only a restart could restore it to its normal state.
The error memory is empty.

Assumptions:

- It's probably unlikely that the motor electronics temporarily 'glitched' or 'froze,' right?

- If the actuator responsible for controlling the fuel injection amount has received a signal, shouldn't an error code be stored as well?

- A mechanical problem in the pump is conceivable (e.g., the adjustment ring for the injection quantity is jammed) - it remains to be seen to what extent the engine control unit detects this.

What do you think?

Anyway, the car worked perfectly normally after that.

Best regards,
Manuel

1500 RPM at idle and no response from the accelerator pedal usually indicates a limp mode due to an error in the accelerator pedal system.

The pedal is then deactivated by the control unit, and a speed of 1500 RPM is provided to allow the vehicle to be driven.
