Headlights strange issue ... please help :(

[MiguelST]

Ok ... a little feedback ...
2013 e92 M3
Had the headlights retrofitted by bayoptiks
Worked great for a couple of months


The problem :
When I start the car (and the car is doing the auto leveling on the the headlights
) the head lights and and all the other lights that come on with the switch turn on and off like three or 4 times and the car repeats the auto leveling ..
As soon as that is done .. everything goes back to normal .. lights move as the should ... or at least I think they do .. no errors on the dash
If I turn the car on with the switch in on instead of auto (headlight switch ) head lights turn on and nothing happens ... everything normal ..

Things I have done ..
Remove the headlights ... clean all connections verify inside to see everything is in place ...
Remove and clean ballast and adaptive modules
Tried unplugging one headlight assembly and turned on te see if I could isolate the problem ... (same result)

What the f—k can this be ??

Here is a video of the problem

Maybe your actual headlight switch is the issue. Try another headlight switch. Could be an issue in the switch for the auto turn on.

Hmmmm never thought of that

But it only happens at start up ...

If it only happens on auto, I'd check the rain sensor.

Not sure about Bayoptics, but this is common on most aftermarket LED bulbs that are not lux. Mine came with some aftermarket bulbs and I had to switch to OEM due to the flickering aspect...

I have aftermarket bulbs and haven't encountered this even after being modified with bavgruppe products. Ultimately I had someone code OFF the adaptive headlight feature

I suspect its the rain/light sensor, because it only happens on auto mode. I hope someone would post the solution for this thread

[Hey Ant]

I dont have aftermarket headlights but same issue. Had my friend from BMW check it out and turns out to be the CAS module. Replaced and reprogrammed, all better.
