kurzes Aufblitzen der Tachobeleuchtung | Posts 16+

Hi!
@Ulf: The G4 still doesn't have an integrated vehicle network system (which is a good thing, perhaps?!), and according to the service manual, the lighting is completely controlled by the dimmer.

Best regards,
Dirk.

I think so too, about the luck.

So, if everything is directly connected to the dimmer, then everything should flash synchronously.
If only the AI flashes, it likely uses the dimmer voltage as a control signal and generates its own control signal for the LEDs (like my radio).

Then, in my opinion, the error lies in the AI.
