Adaptive headlight issue, code clearing w/ BMWhat, dash light still on

I'm new to working on BMWs and looking for a little help. I'm usually wrenching on a 76 Bronco, a much different animal. I apologize for the length of this post but there is a lot to cover.

Hit a pothole a while back and immediately got the adaptive headlight warning light. After a lot of internet research I figured out how to remove the bumper and inspect the headlight. I eventually found the ball joint that popped out.

None of the pictures I found online helped me identify the problem so when I finally figured it out I took a couple pics to maybe help someone else out if they had the same issue. I have a 2007 328xi Coupe, I'm not sure if the headlight assembly is different than on the sedans.

I popped the ball joint back in and then reassembled the front of my car. Started my car and saw that both headlights were cycling up and down, only one headlight was doing this before the fix. I assume the issue was fixed but the warning light continued to light up on the dash.

After doing more internet research I found some products that could read BMW fault codes but couldn't clear them. I came across the BMWhat iPhone app which claims to be able to clear fault codes. I ordered the Elm327 OBD2 adapter off of Amazon and downloaded the app which was $50. A little pricey but if it worked like it claimed it would be well worth it.

Ran a diagnoses with the app and the following 7 fault codes came up.

0. Motor Control:
<--------------------------->
Engine / Motor:
- Fault: Message (transmit data 3, 3B1) are missing
- Code: BMW CDB4
- Fault: Power-management power failure / Electrical system power management
- Code: BMW 2DEB
<===========================>
1. ABS / DSC / Brake:
<--------------------------->
Dynamische Stabilitaets Kontrolle / DSC:
- Fault: :Steering angle sensor
- Code: BMW 5EBA
<===========================>
3. Transmission Control:
Transmission / Getriebesteuerung:
- Fault: VGSG wheel Notlaufregelung activated. No DXC desired torque setting
- Code: BMW 55C3
<===========================>
7. Immobilizer System:
<--------------------------->
CAS:
- Fault: brake light
- Code: BMW A0B0
- Fault: EWS4 fault
- Code: BMW A10A
<===========================>
16. Body:
Fussraummodul /FRM:
- Fault: Disturbed communication links with StepperMotorBox / Short circuit or interruption of the contacts on the back door
- Code: BMW 9CBD


I attempted to clear the codes with the app and succeeded in clearing all but one of the codes. The one code I cannot clear (which I'm assuming could mean that it might be an actual issue) is:
Engine / Motor:
- Fault: Message (transmit data 3, 3B1) are missing
- Code: BMW CDB4
If anyone has successfully dealt with this issue please let me know.

So my main question is, has anyone fixed an issue, cleared the code, and still had the warning light on the dash? I can't figure out how to get the damn light to go out. The lights are working fine, the fault code isn't appearing, but the warning light still comes on. Obviously I'm trying to avoid going to the dealership and pissing my money away. Any help would be GREATLY appreciated.

That error means there is an issue with communication to te stepper motor controller, smc II.

It's the small box under the headlight. Check the connections, most likely water damage, corrosion.

You can buy a used module and code it in.

To clarify, you are referring to error 9CBD? This error code has been cleared and has not returned. If there were still an issue with the stepper motor controller wouldn't the error reappear after being cleared?

I will take a closer look at the SMC II module regardless. Thanks!

Scan the frm again. I bet there is a code.

The FRM does a self check of the adaptive lighting system every time ignition is switched on.

Scanned again last night, below is the entire report, no codes besides the one for the transmission. Guess I'll either have to learn to ignore the warning or visit the dealership.

Do you know if the scanner you're using pulls shadow faults? Might be stored as a shadow fault but the adaptive error should not be present. Does the adaptive system work as it should?
