Hi, I'm new to vehicle diagnostics, but I am facing an expensive aircon flap motor change, and understand that it's possible to change the flap motor. However this requires programming with the VCDS OBD kit. I have never done this, so I'll be careful, but I wonder whether anyone can advise on which kit to buy, please? I have a decent laptop, but that's all. Any recommendations please for what is a good purchase, with proper software? Cheers, Chris
