Want to replace the N75 of a 2002 B6 A4 (just to be sure, and to have a 'known good' on the shelf).

a) what is the latest OEM part number for the AWB engine?
b) same for all 1.8T (B5 and B6) engines?
c) Are aftermarket N75 reliable? Or only OEM if I want to be sure?

Get hold of ECS or some other online store with a good rep. Also, stay with OEM. I have been disappointed several time years ago with aftermarket... As Audi used to advertise, "Maintain the Integrity"

058 906 283F (old part number: 058 906 283C) - part number 06A 906 283E (factory forward supercession)

It plumbs in almost upside down to the J valve i had on there previously and the hose connections are on the opposite side.

The only difference I could find is this:
058-906-283-C 20-30 ohm
058-906-283-F 25-35 ohm
034-906-283-H 25-45 ohm
034-906-283-J 20-40 ohm
034-906-283-K 20-40 ohm
