Diode?? You mean thermal protector??
A/C Compressor Diode
Hi guys,
I bought a whole, used A/C system to install on my 90 CQ. I noticed it didn't have the diode on the compressor. Anyone know the p/n and where/how to install?
Thanks,
Khai

It's just there to prevent a voltage spike.....
"Audi issued a service bulletin, Group 87 # 92-02 on 4/08/92 for the 1988-91 Audi 100/200/V8/80/90 indicating that a new A/C compressor relay and a different compressor magnetic clutch wiring harness with a zener diode was used to eliminate a voltage spike that can occur when the compressor clutch cycles on and off during normal operation."
