Xenon Headlight Help

Hi everyone. My driver side headlight is really annoying. It started after a small accident a year and a half ago where someone backed into me, smashed my hood and pushed my headlights in a little. The shop apparently didn't do a good job of fixing the headlight even though they charged the insurance company a full $800 for a replacement. I now know they didn't actually replace it because my headlight shrouds and high-beam bowls are painted and I know it was my work. The passenger side is fine, but the other one seems to have a loose connection somewhere. For a long time, it was only once in a while when it wouldn't come on. Now, it's out most of the time and only occasionally comes on when I turn the headlights on. Sometimes flipping the brights on or turning the lights on and off a few times will ignite it. Also, sometimes when it's working and I take a corner to the right quickly, usually if I go over a bump around the corner, the light will flash or flicker like something's just loose.

BMW Scanner gives me this:

XENL -> 14/3F - Starting not successful
2A/0A - Terminal 15 < 7,5 Volt
0C/08 - D2S/R-Lamp is off
0D/01 - D2S/R-Lamp gone off several times

I really don't want to take my headlights all the way out and swap ballasts and igniters if I don't have to, so I was hoping someone might have some experience with this. Thanks in advance for any ideas or help you can provide.

First of all if you have proof that they charged the insurance and didnt replace the light. You have an obligation to report that.

Second...the error is reporting that there is less than the required supply voltage to the ballast to fire the light. Think of the ballast as a big charge station. 12v power is fed and then multiplied to 30,000+ volts and then is sent to the bulb for a milisecond until the light fires.

I would make sure the connection going to the ballast is not corroded. A good thing to have is electrical spray. You can get a can at autozone or napa called CRC electrical spray. spray your connections with CRC electrical spray and then get some lithium grease or some dielectric grease and lightly dab a couple times onto the plug before you reinsert. this will protect it from future corrosion.

Thanks Loaded. As far as the insurance goes, the shop offered to take the car back and take a look but that was well over a year ago and I was lazy and didn't take it in. My own fault for not taking care of it right away. I thought about calling the insurance but they said they would fix it so I didn't worry about it.

As far as electrical connections, which ones exactly? Obviously I will check the easily accessible connection where the bulb is first, but do I need to take the headlight out to get to the connection on the ballast? Couldn't find anything that shows what the ballast looks like. If someone has or knows where to find pictures of where the ballast is located and where the connections are on it, that would be awesome.

Thank you!
