not sure if anyone can help.

i have a 2006 RS4 B7 saloon

my car has adaptive xenons but not autolights/ auto dim mirror and i want the coming home light function (where the headlights or foglights come on when you unlock the car with the remote fob)

i understand this can be done using VCDS but the lights will come on whether its day or night as my car doesnt have the auto light function.

can anyone send instructions as to how this can be done on vcds? ie what specific code needs to be inputted?
