Problem with AFL lights, no high beam

[rabbit]

Hello.
I have 2009 year Insignia and I have a problem with my AFL lights. When the light switch is set to auto, then I sometimes get service AFL message. I have read the fault codes and the code is U1522 Lin Bus 2 lost communication with device 2. This fault code is stored as intermittent. I have Delphi DS150 diagnostic tool and I tested the headlight, all headlight motors work perfectly.
Does anybody know, how to fix this problem? Could it be xenon bulb issue or maybe is the headlight module faulty?

Does you high beam works?

When I get service afl message and yellow AFL lamp lights up then high beam won't work.

Can you check if all other bulbs working I'm not up to speed with preface do the AFL have cornering bulbs in them? might be blown cornering bulb so when on auto it triggers the error, failing that then it will get more expensive

As said worth checking the cornering bulbs as these will cause error messages.

I have checked all bulbs and they are working. I just remembered that a week ago I noticed that when it got service afl message then right side xenon bulb didn't work and the 1522 fault code was stored as permanent. I think i should try to change headlight ballasts and when the fault goes to the left headlight, then it's faulty ballast.

Chances are its a ballast,on the preface they were mounted underneath the headlight,asking for water to leak into them. on the facelift theyre side mounted,so the penny must have dropped
