Jon, this is what my fuse box looks like:

Does yours have a sticker on the fuse box?

To answer a couple of questions:
I not sure if a standard Audi 80 has two radiator (I wouldnt think so, but a 5 cylinder may do?)
I dont know about the DV.
The injectors look the same to me (green in colour).
You are right, the coolant should be pink, G12 or whatever its called?
Also, do you have the Porsche/Audi hand book?
