Hi, i installed automatic lighting into my car but I cant get it to work.
I put in a sensor part number 5q0955547b, light switch 5E0941431D and add a repair cable from pin 2 on the connector block on the light switch to pin 16 on the 72 pin plug to the bcm.
Then on vcds i changed byte 6 to installed. The automatic windscreen wiper work. I have tried bought another switch and also tried a different cable.

1 Fault Found:
929796 - Light Switch
U110B 00 [00001001] - No Communcations
[Lichtschalterkeine Kommunikation]

It also shows the part number for the sensor

It would be a start to provide the vehicle details and post a full auto-scan.

OK, pre Facelift

Byte 7 is incorrectly coded; the Octavia does not have a headlight switch connected via LIN bus.

Thanks, do you know what I need to change? Remove byte 7 but do I need to change anything else?
