Left headlight not working...

[ard]

Also a 2007? UK spec? What motor? WHat type of headlights are on that?

I can grab a schematic for you.




(Oh, usually when people sell cars they fix the easy stuff.... )

I also just replaced the right xenon headlight bulb in my X5 last night. Thought it would be an easy fix but that didn’t work so now I’m wondering what the problem is.

I will check the fuses and troubleshoot further tomorrow but what did you end up replacing to fix yours - the HID Module - if so, where is that located ?

I am planning to troubleshoot by swapping the left headlight parts (ballast, bulb, etc) on the right side to see if those still parts work on the right side.

I have a Foxwell 510 BMW Scanner so I’ll try to scan for headlight or module codes and see if my scanner will see a problem.

I had a buddy go through this a couple of months back. He was getting a FRM code. After a lot of diagnosing with a multimeter and switching left for right, ect... He took it to the dealer, who could get the light to come on when hooked up to their computer, but not without. Service Manager said they could try a new FRM, but it would have to be coded to his particular X5 and not reversible, so he would get charged regardless if it worked or not. $600 IIRC.
He used my INSTA or INPA to go in and reset the FRM. He read somewhere online that once the FRM error is triggered and cleared 50 times, it needs to be reset directly. I'm trying to get a hold of him, as it wasn't just a clear code issue, it was more like he had to reset the module. Kinda of like doing a factory reset on a smartphone or computer.
Problem solved.
So, the new FRM would have fixed the problem, but was a very expensive solution.

On the ‘07 it’s most likely the footwell module. It’s a poor design. If there is a problem with the light, like bad ballast, wiring, etc the module will only reset the circuit 50 times then self destruct. It’s not possible to reset when this happens and the module must be replaced. The idiotic problem was fixed after 2009. On 2010+ models you can reset with ISTA. You can read the error as well. The reset function doesn’t do anything in the 2007 model, it’s pointless.
