Default Rear Headlight Leveling Sensor - Plug

Alright guys quick question for you, and I believe I already know the answer, but figured I would ask just in case. Yesterday I was dropping the rear end on the M3 again for some new work I am doing and sending out the diff for some goodies to be replaced

....anyways, while dropping the rear end the Rear Headlight Leveling Sensor, clip/plug end managed to get wedged between the jack and subframe, which resulted in a cracked/broken clip. I believe this is tied into the main wiring harness, thus not a simple replace. I am guessing I would need to find a used clip and simply tap into the existing harness and reuse the new one. Please let me know if anyone else has had a similar issue and how you went about replacing/fixing things or if I am easily overlooking a better solution.

Photo borrowed from another thread...Original location of Sensor

Photo of Sensor Clip (current broken state )

Thanks,
Kyle

If it still works, reconnect, zip tie, you're good to go?

Did you cut the wires?

Yes it still works and no I did not cut the wires. A zip tie may work, but not 100% as there is no true way to connect it back and secure it to the sensor itself. Plus it will no longer be "weather proof" which isnt a huge concern, but always something to think about.

Short of a proper fix (new harness connector, splicing wires), I'd reconnect, zip tie... and for "weather proofing", a little silicone bead would do the trick.

Im parting out a convertible. I can cut the connector with extra wire if you'd like.
Send me a PM if you would like it.

I broke mine as well. I don't notice any difference between before and after it broke so I'm just going to let it go.

Protip: same connector and housing as the vanos solenoid.

Is this really necessary to replace? Mine broke a while back and haven't noticed any difference from before it broke

I might not understand exactly what you said, but why not just order a new plug connector, pull the wiring pins out of the old connector and insert them into the new plug?

Seems like a lot more work to get a used plug with wires and then tap into the harness.

I had the hardest time unclipping mine so I managed to break it as well.

Thank you for the tip guys.
