Hey to all you good people here!
Firstly, I am sorry if I didn't find my answer, and it was here all along. I searched and searched but no luck.
I have a BMW e92 2008 325i and this happens every day now:
When i start the car, the right xenon headlight flickers exactly 3 times.
It starts ok, but then after like 5-10 seconds the right one starts to flicker with a time interval of like 2 seconds.
It turns on, turns off, 3 times in a row, and after the third time the light is fine.
No flickering or what so ever for hours. No error comes up while the light flickers.
When the flickering stops, the error comes up on my board and it stays there for 5-10 minutes and then it's gone...
I changed the bulb and it was ok for 3 days. Yesterday it started again...
I am neither an expert nor a mechanic. I just know the basics
I thank you for your opinions!

Xenon control unit is the most likely cause if you've already changed out the bulb/ignitor unit.

You could also swap headlight modules to see if the flickering moves to the left or still stays on the right
You've written only about changed bulbs. Maybe is it enough to replace ingniters? Is it happened on both sides?

I think the bulb and ignitor comes as one unit.

Sorry, I mistook the ingniter with control unit. Is it happened for one or both lights?

Thanks for the reply guys!
This happens only with the right headlight. No problems on the left one.
When you say Xenon control, do you mean the ballast?
I am also going to say that nothing happens on bumps and holes on the road. This problem occurs only when I start the car, just the right side, and exactly 3 times (flickering). Always 3 times. Sometimes it doesn't. This morning and yesterday for example, it didn't flicker. I don't know if a cold weather can be a reason for this ...
Look at part no. 2. Before you will ask about price try to use this from second light. I think sometimes it is enough to disconnect ecu for longer or code it with NCS Expert to default settings. I don't have experience with xenon ecu so maybe I'm wrong

Correct. Part number 2 is the xenon control unit. You replaced part #1 correct? If you replaced the bulb and ignitor unit, then the only other component is the control unit.

Yes, just part #1. But, Where can I find part #2? Is it under the headlight somewhere? I'll check with google thank you
Mounted to the bottom of the headlight. Have to take the bumper off and headlight out. Or at least loosen everything up.
