Ok, Audi/VW dealers have a computer called VAS (I've often been told its name is "VAG", but i read VAS on it at my dealer). Once connected to your car, you can easily use it to reprogram the electrronics in the car. Now, What if I wanted to do the same wuth my laptop? DOes anybody know if there's some home made converter/adapter, and, of course, if there's any way to get the software or a compatible GPL version (I actually heard from a friend there could be one...)?
