I am new to all this VAGcom stuff. Anyways, I was wondering what are the possible mods I can do with one for a 2002 A4. I went on the RossTech site but couldn't make much sense of the information there. I did hear you can modify it so your fogs work when your parking lights are on. That one I'd be interested in. Just seeing if there are any other popular one's I've not heard of. Thanks

Fog lights and daytime running lights can be added/modified...

Another common one is changing the lock functions as outlined at VAG-COM.

A lot of other things can be done/checked but these are the most common.
