If you have the bi-zenons and adaptive headlamps, then the "highbeams" are used for the daytime running lamps at 1/2 strength. These (inner lamps) are also the "flashing lamps". I believe that the bulbs should be H7s, not the H8s that you mentioned.

 

Thank you for the info. I will swap out those bulbs. I suppose the bulb is on its way out which is causing this intermittent error.

At least there's no permanent dash light for it lol

 

So I added load resisters on the right side, which was the problem area. Then the problem jumped to the left side! So I added load resisters to the left side headlamp thinking I finally had the gremlin cornered, and now at startup, I get a quick left/right parking lamp malfunction message, then it self corrects and stays extinguished for the remainder of the drive.

I guess I'll have to live with that. I'm chalking this one up to my 2007.5 model year, half Mexican edition half German edition. It goes away so fast I'm not sure its even worth addressing further. Annoying though, after several hours of coding, labor and about $50 in load resistors, still an issue, albeit a different one.

 

Code the voltage monitoring out on your halos. Use Carly for BMW or one of the other software packages.

 

It's a bad resistor or angel eyes ballast. some cheaper LED H8 kits have this issue. You should get the part swapped. If it continues then it's not designed for your vehicle (H8 is universal but it only works well on certain cars unless the factory knows which resistor goes to which car).

For example, the ICETEC units we sell for H8 work great in every H8 application except the F01 and E63/4 LCI. For those cars, it requires a special resistor that we sell as a separate (same price) option.

Only on 2004-2007, 2008+ which is what he has is caused by a faulty resistor or bad ballast from the angel eyes.

are you using LED turn signals? do they flash fast when signaling?

DRL are the angel eyes for 2008+ cars
DRL are the high beam at 50% on 2004-2007 cars.
Flash to pass on 2004-2007 is the inner "high beam", 2008+ is the bixenon shutter.


this is how resistors work, they trick the computer AFTER it does the check. So you will see this until you do a capacitor and/or what JTB says below.

Best idea yet. Most people don't have that and a capacitor tends to work better in terms of one-time cost, but coding definitely the way to go.

 

As mentioned, I started this by coding off all six checking functions for the parking lamps. Did the exact same procedure on my 2006 M5 and never had a single issue, plus I did verify the coding "took" because when I read the LCM script, the changes are there.

 

Also, again, I started this journey with coded-off parking lamps... The computer is ignoring its coding...

 

+1 on that i have BMWhat app and it also does not work
