Co oznacza ten kod błędu?
The xenon lamp control module (GDM) registers a speed signal that stays at a value that is too high for a longer period. The cause can be an incorrect speed signal from the instrument panel, intermittent short circuits or loose wiring in the signal cable, or electrical interference. The headlamps are set to their lowest position.
