    Default audi a6 c6 remove bulb cold diagnosis from bcm eeprom

    Hello everyone ! i installed on my audi a6 c6 headlights with led, previous was halogen. Now on dashbord have error with bulbs. Vcds doesn't have any option for this car to turn off cold diagnosis, the only way to solve my problem i think is to read eeprom from bcm and modify the byte that contain cold diagnosis. I already read the eeprom from BCM but i don't know which byte have the info. I tryed to change some values but with no luck. Could somebody help me...maybe someone knows how to do it or tell me where i could find some infos.I uploaded the bcm dump here.
    Thank you !

    Cant view eeprom file whilst naked in bed, but your going be looking
    at thousands of possable hits.

    can only think

    online see if will toggle

    used bcm that does the job

    read eeprom, put halogen bulbs in, clear codes
    unplug halogen bulbs see what bytes changed
    that entire line fill with 00

    fit reistors but that crap idea

    So

    1) give up
    2) not that module
    3) buy correct module
    4) try on line coding

    On line coding

    where some utter cockwomble had made is so YOUR car, that YOU own >>MUST<< go to main dealership
    even if the nearest dealership is a seven hour boat ride away, connected to internet
    where some crout checks that the dealership is real, then changes the settings

    not my job part numbers try. Google. Parts link 24

    oh there is a thanks button, if stiff. Press harder
