regarding i-drive: you don't have to adjust it manually

That's a lot of frickin rice!!! Are you taking your e90 to harvest rice in the fields???

i did a little research for you guys

the proper way would be to adjust the ride height sensor. there is one in the front on a control arm and one in the rear. it will stand out.
by adjusting this sensor you will effectively maintain the full range of motion out of your adaptive head light system. now you may not be able to make much of a adjustment. and you may have to alter the length of the rod.

for small drops a simple head light adjustment(at the headlight) may work. but if you are going more than a inch i would look into adjusting this sensor.

it might be wise to check if the sensors are different between the low slung sports suspension and the normal rough road suspension

i cant read long drafts...tend to forget where im going with this..got any pics for a step by step guidance?

[romain]

plz, someone gives a step by step pictures.

[foofighter]

what he's saying is as you lower the car the amount of sweep the leveling arm has is reduced. I believe like Audi, BMW has an adjustment to alter that range so that it will compensate for the lowering you just did.

[ctgazer]

found out that on pre-sept. production cars, you MUST have dealer activate/de-activate the drl's not matter if you have i-drive or not...post sept. production however can be adjusted via i-drive or the left bc stick (:doh thats y i cant change mine through i-drive)..all this curteosy of e90fleet ofcourse

Sorry for reviving this thread but I can't seem to find any instructions on how to adjust the ride height sensors. My car's headlights are aiming way too low despite manually adjusting it with the philips screwdriver. It's already at its highest position but its still way too low then before. I'm convinced that I need to do something with the sensor (or the sensor is broken)? this is what i'm talking about: http://realoem.com/bmw/showparts.do?...66&hg=33&fg=30

Anyone have any ideas or DIY's to adjust it to make the sensor "feel" the car is higher than it is? I have Eibach springs with Bilstein shocks installed.

[V1_R]

there is a lot of threads about this topic but no decisive DIY or answer.

Phozenstone: did you figure out the issue or how to fix it?

[Ph0zenstone]

nope not yet....i brought it to the dealer, got BOTH headlights replaced under warranty and problem is still there. I'm convinced its the leveling sensor but the dealer said they checked it and its fine...i checked myself 2 weeks ago when swapping wheels and saw that both sensors are indeed intact and mounted. But how do i check if they are just mounted and not actually working?

i have another appointment in late December to drop off the car, i think i will un-install my lowering springs and shocks this time and have them check it out again...i'm afraid they'll blame it on the aftermarket springs/shocks and void warranty.

Has anyone else successfully corrected this problem yet? The weird thing is that after lowering my car, the adaptive headlights still worked until a couple months ago

[BMW1986]

Had this happen to me as well after I installed my H & R Sport Springs. I just adjusted them with the screwdriver. However; they should auto level no?

[Ph0zenstone]

i adjusted it with a screwdriver too but they only go up so far, still not as good as stock. and i'd like to get the autoleveling working again...argh!

[itsbrokeagain]

I don't know what kinda problems you guys have been having. I have aimed them up manually via the screwdriver and never had an issue whatsoever. You do not loose any range of movement up or down. No adjusting of the sensors or anything.

I do this with all my customers cars.

Phonzenstone you should stop by the shop so I can take a look at it. One of them might be inoperative and throwing the whole system off.

hey Matt - yeh i might actually bring it by in late November...are you there on the weekend? I might actually get my oem springs swapped back in. I noticed the headlights not autoleveling and the rear sensor hanging loose so i took it to the dealer. they replaced both headlights (cost them over $2K!) and popped the sensor back in but same issue still. i scheduled an appoint with them in late December anyway to take a look at it again.

[Misturrtinnie]

Best thing to do is check if both auto leveling sensors are still on your control arm. After my coilover installation and a dyno, somehow the bracket came off the control arm and my headlights pointed down to the ground. I knew something was wrong and lifted up the rear and found the rod and bracket dangling. Installed it back on, and it auto levels perfectly! Hopefully that help you guys out a bit. Just check just in case.

[Ph0zenstone]

yeh i checked and they are both intact...the rear one WAS dangling at one point and i had the dealer put it back on, but still doesnt work!

where is this exactly? in the engine bay?

[Chard]

bump. having the same issue; my headlights are pointing straight down and the test sequence isn't working when the lights first turn on. the adaptive part is still working (headlights turn left and right) but they aren't auto leveling.

I checked the front sensor to make sure it's still attached to the control arm and it is. I didn't touch the back so it should be fine.

any solution?

[e90332255]

I had the same problem, lights shot straight into the road and had to adjust them with a screwdriver as well. Now they don't really move around like they used to before I lowered the car they just turn on.

So I guess the answer to ure question is yea you will lose that feature if you aggressively drop it.

[swifty]

does anyone know how to adjust this via idrive ... not being lazy ... just want to know how to do it.

[Chard]

I figured out the reason for this. To all people who said to just adjust it manually at the headlights, that is NOT the solution.

I took a look at the level sensor again in the driver's side wheel well. It's basically a servo with an arm that connects to the control arm via 2 ball joints. When reclipping this, it's easy to let the servo arm drop, making it stand perpendicular. This is because that arm has ball joints on both ends. By standing perpendicular, the sensor is telling the car that the front is lifted, making the headlights point straight down.

Just unclip the arm at the control arm, readjust the servo arm so that it's horizontal, and reclip to the control arm. Presto!

Double check this FIRST if you're getting this problem after lowering. DO NOT adjust the headlights manually first.

Check out this pic from ini's DIY.



I made notes on the pic. The self level arm can easily swing down while you have it unclipped during suspension install. When you go back to clip it, you can easily just grab the clip end of the connector arm, basically connecting it with the sensor arm in the fully down position (making the car think the front end is pointed sky high).

Double check your sensor arm and make sure it's horizontal like it is in the pic.
