okay, but the Xenon is noticabely adjusting to the high beam, correct?
There seem to be slightly different versions on the market
for the

1.) Leuchtweitenregelung Steuergerät = LWR Controller
000 044 900 38
996 618 151 15
0307870007

2.) head lamps Litronics
European Version

factory installed (?)
99663105701
99663105801

retrofit (still available)
99663115701
99663115801

Wiring harness (retrofit kit part)
99661298800

As there are different stories on the net, some worked, others didn't, my Question would be, if they are inter changeable?
It was said, that some Porsche Dealers were not even 100% sure, as there might be minor differences in the head lamps and controller units (factory vs. retrofit kit / 996 vs. 986), so one has to try. --> can get expensive
I understand, that the factory can bus supported auto leveling is not available with the retrofit kit, because there are additional sensors (although pretty cheap on ebay) needed.
So retrofitted Litronics can only have high beam leveling via LWR Controller.
Question would be: Could a retrofit Litronic head lamp and a factory installed Litronic head lamp work together, with e.g. a retrofit LWR Controller? I haven't found anything on the net yet.

BTW. KevinH1990, did you change your fuse from 7,5 to 15A?
