    Does anyone have a MY10 S3 or later with rear DRLs enabled? If so can you please post your long coding from your central electronics unit? Byte 18 contains the headlight info, I know a MY10 TT can have rear DRLs enabled by changing the UK default of hex 58 to hex 59.

    This is my current coding hex 2B

    This was a simple change on older cars, you just switched from north American DRLs (front only) to Scandinavian DRLs (front & rear) with VCDS.

    If any of the Ross Tech gurus are reading this perhaps you may know how to code this feature.

    Thanks in advance.

    John can you post up/email to me some screen dumps of the CE pages please, so I can see what the headlight stalk coding page looks like, as I was briefly advised there is a setting within the CE to tell it which stalk is fitted.

    Just had a look at this on my MY11 A3 with Xenons & LED DRLs and byte 18 is showing as 25. The helper shows this as being for an 8P1 !?!??! Anyone have any ideas?
