FREE xenon headlight leveling sensor fix (e46 m3 325 328 330...)

Fix the link that connect the xenon headlight leveling sensor to the front passenger wheel control arm. Bracket for the link was made flimsy and it is aventually going to snap on every xenon car. Part is like $120 which I wasn't going to pay. I just fixed it with 6 zip ties.

1. Take the link off the sensors arm. Put it in the bench wise, add some wd-40 and make the bolt that goes into the sensors arm move with pliers. Move, pivot and spin the bolt for a few minutes until it moves with almost no effort. This is important, if the bolt doesn't move easily it will rip out the zip ties. Spend a few minutes moving it around to make it very lose.

2. Now take a hammer and punch the other side completely out so that its just an empty hole/circle, you will put zip ties through here. It comes out pretty easy with a hammer.

3. Install the link back into the sensors arm with the bolt that now pivot and moves effortlessly. Zip tie the bottom hole to the control arm, make sure to zip tie it at about the same hight and location where it would normally go (important). About half way up the control arm and to the left of the original bracket. I used 7 zip ties I think. Make sure you DO NOT over tighten the zip ties. If you do they will brake over time, let them all be a bit lose so that the link/hole can move & rotate a few millimeters in every direction.

Sensor isn't the problem, bracket is.
