Audi A6 Diagnosis: Troubleshooting & Repair

Hello everyone,
I'm new to this forum and couldn't find a suitable topic for my Audi problem.
I recently acquired an Audi A6 C4 2.5 TDI Avant Quattro, manufactured in 1996. It's practically a wreck, but I wanted it.

Now, to my problem: Actually, everything is only working partially. For that reason, I had someone perform a diagnostic test on the engine control unit using VAG-Com 3.11.
Now I have the values (at operating temperature), but I don't know the target values.

Can anyone possibly help me?
I'd be happy to list those values here.

Of course, I could take it to a VAG workshop, but I absolutely can't afford it.

Gerhard.
