We built a setup to connect a laptop to my brothers chevy suburban, we can read the ecm and clear codes and even copy the program. Is there anyone with any info on building anything for the audi? Even if it will just read codes and clear them. We have an old laptop that works good for this. (serial, usb, parallel, pcmcia). I know vag/com has some software, but the cables are $$$$. trying to build some.

yes i was wondering about that too.

not sure if vagcom still supports this interface with their newer releases.

I use this with an early release of the software.
