Z4 Xenons not levelling

[Jimmy No Hands]

I was driving home tonight and my xenons seem to be adamantly pointing to the floor. So much so that I couldn't really see at all. Having parked up and left the car for 20 minutes or so and tried again I've noticed that they are not cycling up and down when first turned on like they used to.

So, is this tied into a sensor somewhere or could it be a fuse? Help PH.

Hello. There are 2 sensors for the leveling system. They fit on the chassis,with a small link like an anti roll link onto the suspension arm. There is one on the rear off side and one on the front. Easy to spot just make sure that the link is not broken or the sensor has seized up. The arm will bend as its plastic. On mobile so hope this comes out ok.:-)

Hello Steve. I've managed to check the front sensor today and it all looks okay. Didn't have time to access the rear before work but having just briefly ran outside and turned my lights on they seem to be aiming forwards again. I'm hoping it's rectified itself!

Update, they seem better than last night but they are still not cycling through when I initially turn them on. So I'm concluding they are toast. I am borrowing a BMW code reader tomorrow so I'm hoping that will shed some light?

This happened to mine, lights just pointing downwards all the time.

Problem was a failed electronic beam leveller in the headlight unit, cost about £250 to fix at BMW.

Oh bugger. Not what I wanted to hear really. Presume it's far from a DIY job?

[Jimmy No Hands]

Any idea what the part # or name is?

I had the same on my previous M5 - got it fixed under warranty. Point is though the bmw tech told me that the car was not road legal without the leveller working.

Not sure if this is true or not, but worth getting sorted asap.

I have seen that when the question of retrofitting has been asked.

[Jimmy No Hands]

Can't find the correct part. Without knowing the exact culprit its difficult. Tempted to take it up to the indy up the road who has been good to me in the past.

Had any suspension work done recently?

The small plastic arms are very easy to break, I don't know the ins and outs but it certainly wasn't a £250 fix on mine a couple of months ago.

Or it could be a motor.

Neither are terribly expensive and much better if you take to an indy and not BMW.

Don't stress.
