Hi,

I change headlights from AHL to Xenon (bixenon). Everything should be plug&play but:
- tms modules not responding
- high beam not work (car have high beam assist)

Of course I do coding changeing 524 to 522.
Headlights missing 3 last pins. 
Pin 10 and 9 is a can needed only for AHL, pin 8 is lin.
Both lamp don't have pin 8 so how they communicating with frm for example?

Have you looked at wiring diagram for bi-xenon lights? There must be bus line!

Hi,

Yes I look at wiring diagram.

I suggested this dogram:

It is for AHL.

I could't find for 522 but I thing it will be that same. In ori Xenon LCI light pins 9-12 are empty, so there is no can bus only lin bus on pin 8...

samething <bad> with cars wiring...
