Need Help Urgently - e55 headlight issue
My drivers side headlight went out about a month ago, tried new bulb and ballast and everything, nothing would work, so I ordered the replica facelift headlights, installed them, and the drivers side headlamp wouldn't turn on, and also the indicator wouldn't work.
So then i ordered a complete new OEM headlight assembly, and that seemed to fix the problem... for about 2 weeks. Then I went to turn the car on a couple nights ago and boom "low beam, left" appears and drivers side headlight isn't working again! So today I took it up to the stealership and they had it for about 2 hours and told me the bulb must have gone as nothing was showing up on STAR (that is if they even checked for ****ing anything). They try to charge me $300 for a new bulb, I tell them that better include a handjob and that I have replacement bulbs back up at my shop anyways.
So I replace the headlight bulb (it looks absolutely fine) and it still doesn't work. I even swap over the ignitors on the back of the bulbs, switch the bulbs around, and still nothing on the drivers side and passenger side works absolutely fine!
I have been reading that this could be a SAM issue, but I have scoured the internet and this forum and cannot find where these SAMs are located?? Could this be the issue? Is there a way to test the SAM etc?
I really badly need help as this is my daily and currently I am unable to drive at night! Any help would be greatly appreciated, thank you very much!!
The tech came out and told me that they hooked it up to STAR and it showed no faults or anything! I know they definitely hooked it up because they cleared my red battery screen from showing up.
