might be a worthwhile investment.

I have an Actron that works just fine. As Greg said, they won't read the manufacturer extended codes (chassis, special controllers, etc.), but they will read the basic engine codes.

I have an indy mechanic that has the Chevy specific tool. He read the codes on the 'vette when the brake and traction control module went out. It was still under warranty, so he sent me off to the dealer and didn't charge me a dime.

The 'vette is now gone and an Audi A6 has taken it's place. It has the same issue as all new vehicles in that the reader only pulls the most basic codes. The aftermarket reader for it is a $350 software and cable package you run on a laptop. It allows you access to a ton of features and settings that only the dealer can see. Stuff like turning on the window up/down from your keyfob, internal and external lighting settings, playing DVDs on the screen while moving, etc. And many service modes, too. With the 100k mile warranty, I doubt I'll pop for it, though.
