Hello,

I have superb 2008, 09 model (3T, mk2)

I swapped all lights to LED, no error appeared except rear licence plate.

I have I believe VCDS (but Russian variant, called vasyadiagnost, live in post CIS country):

Where I go to 9 block, byte 23, bit 6 disable 

And 17 byte, bit 7 enable

And this coding is saved, but error appears withing few seconds after erasing it. I tried turning off and off car, locking, unlocking, leaving overnight, driving 50-100 km. Errors shows up anyway. Other adaptations that I tried - work no problem, except this one.

Can anyone please recommend me where to look?

Your BCM hardware is probably too old to support LED lighting.

- You could add load resistors to fool the BCM

- You could try replacing for a newer BCM

- You could try editing the lighting EEPROM in the BCM to disable the check there (needs VCP/ODIS-e)

 

No guarantee the EEPROM method will work on such an old BCM.

Thanks for your reply!

 

Getting new BCM module seems not a trivial task, and will require skill and knowledge more than I have. 

About VCP/ODIS-e I've read something, I am searching for people who have that adapter, software is available online as VMware image.

 

Maybe least troubling would be adding load resistors? 

I have to place them parallel to led light right? I understand they will heat, but I assume this heat wouldn't be insufficient for anything dangerous ?
