Those level arms get rusty on the ball. I've had to refurbish a few of them. I've also replaced a couple. When I have a corner apart with level sensor I will lubricate that ball joint.

When I bought my e70 the headlights were aiming low in spite of max up adjustment. Apparently somebody replaced the arm with one the wrong length.

It's made from an aluminum tube with Plastic ends so I pullled off the rod, aimed the lights with my laser level and a target about 30' away just turning the level sensor arm. Measured the length needed to match and fortunately that was shorter like 12mm. I think I've seen mm length on the bars and I'm guessing the wrong one was used. The beam hit the ground like 70' from the car nearly useless on low beam.

My old starter fired right up when I took it out go figure. Also I've noticed if I hit start immediately after putting in the key I'll get a non start. I had thought that was why I got the non start in the past part of why I didn't swap the motor. I did finally get an error related to starter iirc something about terminal 50 and maybe over current. Suggesting the start circuit is monitored and when end of life starter pulls too much current it immediately shuts down. The weird part was I never even heard solenoid click. However I think I figured out finally when it actually wouldn't start for minutes I opened the door and could hear a click so I think it was just solid sound insulation blocked the solenoid click.

My e53 starter did the same. (Spin on power application) but in that case it did pull a lot more current.
