Mystery part-swaybar

[spitfun]

I am looking for the name of this part. It connects to the swaybar on passenger side,I believe it stiffens the shocks up when you go into a hard corner to control roll. Mine seems loose and the arm is bent,I can't find it mentioned anywhere-anybody know what is is called??

Its for the headlight level

Really? I thought it was weird it was only on one side... Thanks

Im sure it is. The headlights automatically level.

Light reveler, if you accelerate the dipped light beam should move down.

There’s one on the front wishbone too :tumbleweed:

100% headlight level sensor. Mine was snapped, BMW wanted over £300 to fix it!!

Fwiw, they're also used to control the air suspension and ride height on X5s, 5er Tourings etc.

On the E89 the level sensors are just for headlight control…damping control is ‘sensed’ by 3 accelerometers only
