Hi, probably covered loads before but trying to work out what exactly needs coding with vcds i.e the code I will need to input. My friend has vcds so once I get code for the unit so I can use it will pop round and code. I've got a b7 a4, I have the half amplified system which is where I'm struggling to work out the code I would need. I have DIS also and would like to have the aux turned on too if I decide to have 1 eventually. And help is greatly appreciated.
