For those who want to install LED headlights and HBA in 6R...

Hello guys,

Recently I retrofit LED headlights and HBA in my 6R, and got very strange bug, see the video:

I tried a lots of coding - without success.
Then I ask iichel and firegrafik, because they have LED headlights and HBA installed, they shared to me that they have the same issue.....sad story, But firegrafik also shared some info, and here it is:
Also it was discovered the increasing that parameters (on the picture) up to the 138-140 makes some positive result but it doesn't make it 100% work
Image

So I tried this with my VCP, increase those values to 140 and finally problem is gone!

I hope this info will be useful for someone who want to go in adventures :lol:

And BIG THANKS to the guys, who help me out to solve this mystery !!!!

I will add for those who doesn't have VCP but have ODIS engineering.

Addresses of that parameters in BCM's EEPROM are 0x2119 and 0x211A

Thank you for sharing your experience and data to solve that problem, ... it is praiseworthy to reveal truths.

Fortunately, this does not happen with Bixenon headlights in conjunction with HBA and any 7E0937090 BCM index (--,B,C,D,E).
