I know it's an old thread, but has anyone an idea how to code a B8.5 so all lights will be off when engine running and light switch in off position? I want to be more stealthy when parked up with the heater on!
My car is a 2015 S-Line and it was simply a question of selecting Byte 3, Bit 0 "Daytime Running Lights adjustable via MMI/Car menu. Then the MMI indeed has the choice of DRL ON or OFF in the Exterior Lighting menu.
I need to be able to park my car with all lights extinguished and the engine running. I do not drive it on the highway with DRL off.
