Thanks for your info, you are clearly very knowledgeable on the subject! As I mentioned, the problem with increasing PL brightness using Dimmwert CD value is that it maintains that value even when headlights are on - which i do not want. The factory functionality is a follows with the light switch position: Off = 100% Full brightness DRL Parking Light = 26% brightness PL Headlights= headlights on + PL @ 26% What I am trying to achieve is this: Off = 100% Full brightness DRL Parking Light = 100% brightness PL Headlights= headlights on + PL @ 26% Hope that’s a bit clearer? thanks..

Hi and thanks for the response. My R is UK spec with LED Drl’s All of the Leuchte values should be standard except for VLB10 Dimmwert CD2 and VRB21 Dimmwert CD3 which I have both increased from 26 to 50 The above coding has successfully resulted in brighter sidelights/parking lights however this level of brightness is maintained even when the full headlights are on, instead of dimming to 26

Hi and Merry Christmas! Can you PLEASE tell me how to enable this in VCDS?? I have been looking for how to do this but all I am finding is information on how to increase the brightness of the DRL which then maintains that same level of brightness when headlights are on - not what I want. What I would like is brighter sidelights but which then dim down as standard when headlights are turned on.. Thanks
