Hello everyone, I drive a 2006 E90, and I have stumbled uppon some problems regarding my headlights.
They started to point down all the time, and they are kinda going crazy, moving up and down while stationary or while driving, doesnt matter.
If I come up to the car, and stand near the headlights, I can hear the motor/actuator move/adjust my headlights up and down, constantly.
I ran a check on car, no codes whatsoever.
I tried to adjust the headlight height with the screwdriver under the hood, on top of the headlight, but the headlight doesnt move at all, or barely moves and comes back down.

What can be the problem?

This is weird. Sounds like an electrical issue. I would try disconnecting the battery for maybe 30min to see if this reset ECU.

Already did it, no effect.

Also have many more electrical issues regarding A/C, took it to the shop, made it worse.
My rear windows stopped working, Cruise control, A/C light is blinking( a/c is full, was at 490g, but i topped it off to be sure, still no effect), my seat heaters dont work, rear windshield heaters also have no function…
I checked all the relays and fuses, all good.
Shop did a reset on FRM Module, but no changes whatsoever.

seems like a dead battery to me.

check that first. If it's old, change it and code it.

Just a little info
My windows, A/C, Cruise control and Headlights were functioning correctly,
BEFORE I took it to the shop.
I had a little problem regarding A/C Unit, my blower only had effect on first 2 Bars, after the 2. bar, no effect, only if I activate the defrosting Windshield, I could regulate the blower from 1. to 7th. Stage and it hat effect.
After I came to the shop, they said my AC Unit was manual, not Automatic like what I had installed.
I said install the old(Automatic) unit, what came with the car and thats it.They did it, and after that all the other stuff stopped working(windows, CC etc.)

Please provide Last-7 Characters of your VIN.
I presume you have Adaptive Xenon headlights? It appears there is a wiring or connector fault in the Front Ride Height Sensor, or in the Sensor itself.

With your VIN-7, we can provide specific suggestions on what to disconnect & HOW to TEST.

Can I post a link to a yt video that shows what the headlights are doing and the buzzing sound from the headlights?

I had problem with adaptive headlight pointing on my 2006 330i once and cause was water had gotten into headlight and the module which controls pointing is mounted in headlight such that the water drains into it.

That said, given you have a lot of other electrical problems it would seem something else is bad/intermittent. Did problems all start suddenly together at some point?, like after a rain? Or did stuff just start going bad one by one?

You said no codes - you mean no codes on dash?, from obdii?, or did someone check with INPA or ISTA? It would seem surprising with the amount of problems described nothing would show in a INPA/ISTA diagnostic.
I agree with gbalthrop - seems you will need some specific diag tests to sort out.

Everything started after I took the car from the shop.
Everything was functioning properly, lights , A/C etc. but i took it to the shop so they can figure out why does the blower work only on first 2 levels, not more.
They swapped the manual AC contorol unit and said it works now, but I didnt like the way it looked, so I said put the original back in and they did.But now it doesnt work at all.

Regarding codes, i wrote the wrong info, sorry for that.

for A/C;

E72D(A/C Valve), E718(A/C Refrigeration Cycle), E723(Front Windshield) E724(Misting Sensor???) E721(AUC Sensor)
Cruise control:

DO21, D029 - both day adaptive cruise control even tho I dont have it?( no camera/sensor in the front bumper visible)

Headlights??
-D02D, 62E9

<— ALL These codes came after I took the car back from the shop.
Car was checked with ISTA in another shop, but I dont have ISTA only Carly,
but the same codes appear, not 1 more or 1 less.

Check your headlights for water. Open rear lid. Check module too. It's located at the bottom of headlights.

Apparently your ECE vehicle has a motorized headlight aim, that is NOT used in US, & with which I am NOT familiar. That is
DIFFERENT from Adaptive Headlight vertical aim on Xenon system. You SHOULD be able to disconnect the 4-pin connector
from the Vertical Aim Adjuster, to see if buzzing ceases in that unit. The Lighting function should remain, as those wires are NOT affected.

In any event, it sounds like your "shop" did something to damage your FRM (Footwell) Module, which controls Lighting Functions.
If all was operating CORRECTLY BEFORE they tried to "Fix" your Blower function, messing with the IHKA module, then it's
time to see how "Reputable" that shop is.

I would suggest that you take the time to understand exactly WHAT is causing your "buzzing" sound BEFORE talking to
the shop. The MORE YOU know, the harder it is for the "shop" to "Blow you off" with BS.

The forums are here to HELP, & many forum members do their OWN work, instead of relying on a shop, where the outcome
is often a "roll of the dice".

So, I opened the headlight covers, no water inside, all dry.
Disconected the adjuster and turned the headlights, no buzzing inside, just the servo-motor/adjuster itself is constantly going up and down.
If i recall correctly, my brother had a same issue half a year ago with his e92, his Xenon module/controller unit was bad, he changed it and since then, no problems whatsoever.
BUT
I tried to adjust the height manually with a screwdriver, but I cant.Its starts going up a bit and just comes back down, like its broken inside or something i dont know.

Now, regarding AC and other stuff.
FRM Module is responsible for light,windows etc.
Rear windows also?
If yes, how do i reset to factory settings the FRM Module and IHKA(AC)
using ISTA?
