Some amount of work, but you can easily test with the stock bulb, just unplug the power to your v4 and put the stock bulb. If you eliminate the v4, the next thing I would check is the CAS module, making sure it's error count is not max'ed out. Some has issue with CAS module error count due to water getting in, but this requires coding to reset it.

Where is the cas module located and can it be reset with inpa ?

I think it's behind the panel where the OBD is, and yes you could reset it with inpa (based on what I've read so far).

Ok thanks I'll try messing with cas module

I had my angel eyes in for almost a year with no problem. Then one day I get the door open gong. Like the other post it's always a different door. Also I get the same issue with the he auto door locks trying to re lock after accelerating from a stop. I put ferrite chokes on the AEs to try and cut down on interference but that did not work either. So odd. Let me know if anyone has any idea other than oem. Oem is so lame I hate to have to go back.

You don't have to go back. You will need better angel eyes that don't throw codes.
I had the same issue and it popped up after 2 months. Had to return the AE and get some guaranteed not to throw codes.

What brand did you go to? thanks for the reply

I think my door open symbol kept coming on when I changed my fog lights. I have Tom headlights with v4

[Jmac335i]

After doing some research I am feeling like a faulty footwell control module could be the reason for the random door ajar warning lights. If the FCM was faulty could it be just this one thing going wrong or would there be more syptoms?

I don't know if this has been mentioned in this thread before but if it has, apologies....

Cheap aftermarket LED lighting can emit EMI into the electrical system and cause intermittent door ajar errors.

I have Tom blackout v4 rings. I also have aftermarket 6k d1s bulbs I got for cheap. Maybe that could be the reason I'm getting the error

I'm having a very similar issue and was seeking any help. Full disclosure, I had my windows tinted one afternoon and this warning started shortly thereafter.
The door ajar alert comes on only when I'm driving. If i sit idle the warning does not come on. The warning shows my rear driver door as the culprit but all my doors are secure. The rear driver door locks/unlocks/functions just fine.

I suspect my door actuator (which would be a relatively cheaper fix) but I wanted to see if anyone else has had this issue before. Thank you for your time.

My issue was the frm module. Do you have any headlight issues ?

So when you say your issue was the FRM module what did you have to do to fix it?

My E82 just started doing this. I don’t have aftermarket lights, car is fully stock. It’s not just one door doing it, it’s both. Sometimes does it when driving but mostly happens after car has been “sleeping” and I unlock it (as in first thing in the morning when I go to work).

Quick vid of what it does: https://streamable.com/8ke5p

I replaced the frm and got it coded

Old thread, new problem for me. But my headlights are stock. It's just that all of a sudden, I started getting the Door Open warnings, it rotates which door is ajar (all are closed).

It seems worse when the car is wet after rain or a particularly dewy morning.

Any more thoughts?
