2005 Mini Cooper HID headlight issue

Weird xenon headlight problem on my mini, in the video there is a chirping that is head louder than in person making me think this may be an alternator issue.

You need to use Canbus type ballast for HID setups.

Same issue with my friends 2006, left head light flickering. Car is due for MOT soon and is wondering will they fail him as hecan’t figure out how too fix it

[@PowerHAguy]

Interesting, I assume you figured it out by now? I have a 2007, which doesn't seem to actually have a way to turn them off, but the left is flickering. Not quite the strobe you have though.

Hi. Did changing the lights resolve this issue? I have this with my 2005 in storage.

[@niels1755]

Dude did you fix this? Cuz I have the exact same problem with a mini I just bought.

[@MADuranDude777]

Hey man how did you fix this?

[@drewstevenson5478]

headlights HID ballast both need replacing Bro but guess you have fixed problem by now i hope

[@omarperez4066]

How do you know it's the ballast?

[@brianjansen1773]

Was not the ballasts, both were replaced and still happened

[@tristanfernandes396]

The BCM is either faulty or needs reprogramming using NCS expect... My BCM was faulty, headlights were permanently on and sometimes strobing something completely off and some of my interior lights didn't work. I tried changing the ballasts and bulbs but had same issue. I used NCS expect to reprogram it but had a communication error with only the BCM, so replaced it with an identical model but just had this strobing issue... After I reprogramed it, changing option to hid, self leveling, sunroof and so on it no longer has an issue.

hey what did you reprorgram to fix this?

[@stevenallman4992]

NCS Expert. Change pulse width. I had this problem as well.

[@omarperez4066]

Well I'm in this boat atm. Let me know if you have fixed it and what you did to fix it please. I just ordered these xenon headlights and the turn on perfectly if the car is off, but once I start my car the flicker like your do. Any advice will help

[@brianjansen1773]

I THINK that for me it was the BCM was replaced by a previous owner but they put in a used non-hid bcm.... I ended up putting in halogen headlamps. But replacing the ballasts would be a good start for you.
