640d....adaptive LED headlight issue....

[turboman786]

I've got a 640d 2012 with the hitherto brilliant LED adaptive lights

The front headlight on one side only stops working intermittently.....initially I thought it was just in need of a new bulb but I'm told by a local specialist that these are sealed units and there is no bulb to change

Has anyone any experience of fixing these lights or am I stuck with a (hugely expensive I suspect) new unit from BMW?

Many thanks for the replies...it appears I'm not alone with led adaptive woes

BMW want £190 to diagnose the fault....but then they say the headlight cannot be repaired so I'm not sure what diagnosis will achieve

Car is unfortunately out of warranty so I'm going to keep researching these forus as I'm confident this is just a sensor issue

The light works until I go around a corner and then I get the dreaded *dipped beam left failure*

The fact that the parts can be bought separately certainly indicates that it's repairable...

OK guys...still no further forward with this

I throw myself to your higher knowledge

- is there anyone with expertise of coding etc who could look into this for me and identify the individual part that ha sfailed or try and clear any error codes?

-is there anyone who can repair these lights.....surely there must be someone!!

Thanks
