H7 LED Headlight Bulb flicker issue

My car is a 2000 E46 sedan. I'm running a new set of CREE LED H7 bulbs in Eagle Eye housings in BOTH low and high beam positions. They are BRIGHT and work very well. However...

When I start the car with the headlights OFF, all four bulbs rapidly flicker a few times, and then will flicker on every 30 seconds - just a quick "blip" of light on all four bulbs simultaneously.

My suspicion is that this is the BMW bulb monitor cycling every 30 seconds to check bulb status. Of course, you never see this with incandescent bulbs, but with these LEDs, they are apparently seeing a slight voltage spike that is kicking them all on for a nanosecond.

HOW do I turn off the bulb monitoring circuit? Do you have any other suggestions? Could the bulb check cycle be re-timed from every 30 seconds to, say, every hour? Or every several hours? That I could handle.

Thanks, but I have no idea what PA Soft is or how to do that. Is there a post that goes through that whole thing?

Solidjake, I obtained the OBDII setup online and tried downloading and installing the PA Soft program (demo version) on my Windows 8 laptop, and have not been able to get it to work right. I read all sorts of articles online about downloading the right drivers, etc., but nothing has worked. Every time I connect to the car and try to run the program, it says, "hardware not ready".

I don't even know if I can turn off Cold Check using the demo version of the software anyway. Would I have to invest $650 in the full version to do that? I'm certainly not going to invest that kind of cash in a 16 year old car that I only tinker with.

I tried calling some local BMW repair shops to see if their diagnostic computers could turn off cold check, and most of them had no idea if they would or would not. That's not something they ever get a request for, apparently.

Any thoughts?

They can do it if they have the coding software,if they specialize in BMWs, it would be a piece of cake. Especially after watching Jake's video. They probably don't want to take the time.
I can do it, and I'm a noob to coding, it's just a check or uncheck.
There is a way to get PA Soft to run on Windows 8. But I can't help there.
If you're in NC, I can do the coding for you.
