I went to turn off my TPMS in my 08 RS4 so when I run my winter tires I don't have the annoying warnings and decided to play around in VAG-COM a bit. Found a few little things....
In 09 - Central Electronics you find the adaptation channels for your lighting as follows:
02-Brake Light Dimming - Mine was set to 22, and according to VAG-COM it has an upper limit of 40. I tried several different values thinking that it might make the brake lights brighter if I had a higher value. I even had my wife watch the brake lights (with my foot on the brake) as I changed values. She didn't notice a big change, but she noticed it getting brighter.
03-Tail Light Dimming - Again, mine was set well below the described upper limit. I didn't mess with this one as I don't mind how the tail lights look now.
04-Rear Fog Light Dimming - Once again, mine was set well below the listed upper limit. I increased mine to the upper limit.
05-DRL Dimming (Halogen) - Doesn't apply to our cars as we have the Bi-Xenons. There is a value of 92% intensity in there.
06-DRL Dimming (Bi-Xenon) - Mine was set at 92% intensity from the factory, but I don't ever use my DRLs. However, I do like the dimmed look when I run just my city lights so I changed the value from 92 to 60%, which made my DRLs dim down to 60% intensity. So, now I may actually run my DRLs since they are more dim.
07-DRL Fogs (Canada) - value for the intensity for Canadian DRLs, which are the Fog Lights.
One thing I did find interesting is that Channel 16, which is the Fog Light Cold Diagnosis is switchable on our cars (it was not switchable on my B7 A4). The Cold Diagnosis causes the system to test if there is a functioning bulb in the fog lights without turning the lights on, and when you disable this you don't get the warning if bulbs are burned out or missing from the fogs (ie DTM edition cars with no Fogs). I left my coding for this alone, but if someone wanted to remove their fogs, or potentially even replace their fogs with S6 LEDs, this could help avoid any issues requiring in-line resistors on that circuit. Not positive, though.
