Xtool vag 401 scan tool. What you guys think.
 

I’m new to the Audi forum. Just bought my first Audi. It’s a 98 a4 b5. It’s a 1.8t 5 spd. It’s got a FMIC, ko4 turbo, giac tune, and some other stuff, I was wondering if anyone has used this vagcom scanner. It was only 50$ from amazon. Need help figuring out how to use it.
