    Cold diagnosis front parking light/DRL Octavia2 RS 1K0937049N

    Hi,

    can someone please help me to switch off the cold diagnosis in this BCM? At least front parking lights/DRL or at all.
    Ive tried so far (untickle) these:

    Byte2 bit2 - "Cold lamp diagnosis active" - NOT WORKING
    Byte19 bit1 - "C.D. Front parking lights active" - NOT WORKING
    Byte18 and 19 no bit tickled - NOT WORKING

    Why?

    Is there any sw solution?

    You need VCP for this.
    Not possible with VCDS.

    I still hope that some day there will be any magic keystroke in VCDS to dowload and upload the PQ lighting configuration as raw hex values..

    Thanks for the answer. I have VCP(original, but used just few times), is it there described well(in coding, adp,guided functions...)? Maybe doing adpmaps with vcds before and after can reveal it?(if it is in coding, a scan might be enough)

    For bordnetz - I never heard that VCP can do any trick
    For BCM - yes ...but not bordnetz

    for Bordnetz I only know people play with resistors inside

    You're right, sorry. I was too fast associating Octavia 2 with BCM......
