Reading fault codes on Audi B5 avant?
I've just bought myself a facelift B5 Audi A4 tdi avant. I missed my old B6 as far as practicality went, and the B5 ticks lots of boxes, as well as not having too much $$ tied up in it.
Anyway, cutting to the chase, it's a pretty good car, with the exception of the alarm! After lots of googling, it looks likely to be the tailgate latch sensor, which is apparently quite common with them.
I bought one of these for the mk2 a while back (when the mk2 Golf VR6 was mis-behaving), but didn't end up using it due to lack of obd2 port!

Also what's the idea of Vagcom? I assume the scanner above is supposed to give fault codes, and Vagcom erases them/ gives the user options to tweak settings?
On their 'site, they list about a million choices:
