Bi-Xenon high beam malfunction causing headlight shut off

The driver side bi-xenon headlight on my 2012 W212 will turn on, auto level and after a minute shut off. Within a minute of powering on, I have attempted to flash the high beam, only to find out that only passenger side flashing and driver side not responding at all.

The bulb and control unit are working fine. This is confirmed after vigorous testing and diagnostic.

I'm getting the following error after running a quick test scan via Xentry Diagnostic Tool:

E1n1 - Left xenon headlamp (XALWA-L)
"9033 The actuator motor for left light distribution has a malfunction"

Anyway to fix the high beams or shall I go ahead and pull the trigger on a new headlight unit which will cost a fortune?

That's what I had to do when I had the same symptoms https://mbworld.org/forums/e-class-w...iver-side.html

You can save by finding a used headlamp assembly on ebay but I went the OEM route under my extended warranty.

Mercedes w212 e220 cdi
[QUOTE=zeemob;7274118]2012 W212 aracımdaki sürücü tarafı bi-xenon far yanacak, otomatik seviyede ve bir dakika sonra kapanacak. Gücü açtıktan sonraki bir dakika içinde, uzun huzmeyi yakmaya çalıştım, yalnızca yolcu tarafının yanıp söndüğünü ve sürücü tarafının hiç tepki vermediğini öğrendim.

Ampul ve kontrol ünitesi iyi çalışıyor. Bu, zorlu testler ve tanılamadan sonra onaylanır.

Xentry Teşhis Aracı ile hızlı bir test taraması yaptıktan sonra aşağıdaki hatayı alıyorum:

E1n1 - Sol xenon far (XALWA-L)
"9033 Sol ışık dağıtımı için aktüatör motorunda bir arıza var"

Neyse, uzun farları düzelteyim mi yoksa devam et ve bir servete mal olacak yeni bir far ünitesi için tetiği çek?[/QUOTE
