Factory

Unfortunately I am unable to place a call on this here myself but others see you have requested a call and may still call on this here.I can however continue here.

Is this low and high beam that is not working or just low beam?

Low and high does not work , just the shark eyes come on at night if you know what i mean
Customer reply replied 6 months ago
I know there is some kind of ballast on bmws but i do not know the location of the ballast

O.k.,the low beam is controlled by a ballast but the high beam is controlled by the light control module itself.The low beam ballast receives a signal from the light control module to turn on the ballast.

With both low and high beams out this indicates the fault isnt in the ballast but with the light control module itselt.The light control module fails internally and fails to send a signal to control these lights.It can still work to work the left side lights but can fail to work the right side lights.

You would need to have the fault codes checked with a compatible scan tool to see what codes are set in the light module as well as have it tested electronically to see if it needs replaced for sure.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
