Xenon Troubles!
Guys, so one of my D1S headlight bulbs burnt out and I replaced it. In doing so, I didn't put on the back cover of my driver side headlight correctly and went into a carwash...we can all guess what happens. The xenon motor still works (I can see the shroud go up and down) and the angel eyes work, but the low beams don't. I swapped out the bulb and the ballast to no avail. The headlight was drenched in water. We got most of it out but we still can't get the low beams to work. Any ideas? I drive an e82 with xenons.

That sucks - did you check the fuses? Make sure you really dry everything around there out including the connector if you do find a blown fuse and replace it. The connector may have corroded internally also which is preventing connections from working.... |

This is done using "Tool32" tool. Since we wouldn't want to link another forum here, do a google search for "The Official Guide To Resetting A Short Circuit Fault In A FRM Module". I hope this helps! Dre |

My understanding is that once the FRM detects a short circuit condition in one of the headlamps, it stops all current from flowing into the shorted light to prevent further damage. This condition is reset using the "Tool32" software mentioned in my previous response. I believe ACL is just a control unit - basically a circuit board that controls the operation of your individual headlamps (there's one on each side of the car). It worked for me but your experience may vary. Best of luck and keep us posted! |

The ballast might be dead. It's the metal casing under the headlight. Any amount of water always end up inside it.

He mentioned above that he's replaced the ballast already. I would check the fuses first, I don't recall if the left / right headlamps are on their own circuits or a shared fuse.

Hey peeps, sorry for leaving you hanging, the car was actually totalled before I had a chance to diagnose the actual issue. I believe it was the FRM not sending current through due to it detecting a short circuit. All it needed was a simple reset I think. Anywho, I got a brand-new ballast for sale!
