OK, I'm a total n00b at this. I did search the archives and visited the Ross site, but I'm overwhelmed by all the info.

Here's my situation: my chipped '99 A4 1.8T is giving me a CEL. Found a guy nearby with a VAG (the VAG locator is great!) but he's not too familiar with it, only used it once. I don't have a Bentley manual for my A4, and don't know where to start to diagnose this problem. OK, I did figure out where to plug the VAG in, but that's about it.

Can someone give me a link to a basic procedure to get me started?

Thanks.

Thanks, tried that. Looks pretty straightforward.

Should the engine be running when we do the scanning? (told you I'm an idiot).

No, engine doesn't have to be running, but key needs to be ON.
