looks like fuse # 8 "heater control relay- ac clutch relay-cooling fan" fuse runs the 12 volt side " black and yellow stripe wire " pcm or ecm runs the ground side "red -blue stripe wire"- what else do you need?

SOURCE: my radiator fan does not work

sound like fan relay .relay for cooling fan is on back fire wall next to the strut tower on the passenger side.

check the internet for a bmw e36 ETM ( electronic troubleshooting manual) everything you need is there.

I have a 2000 Passat (1.8T), and I recently had this code (P0411). First thing I did was to clean the mass airflow sensor (MAF) and reset the code by disconnecting the battery. Unfortunately, the code came back. It also came back with P1426. It ended up being the purge valve ($60 at ECSTuning, $140 at the dealer...I went with ECSTuning). Before you drop money on the part, inspect all of the hoses to ensure they are not cracked or torn.

Here are the locations of the fuses and relays. F-31 through f-42 probably are the one you want to look at. These are probably all tied together from looking at your codes. Your mass air flow sensor is also giving you an alarm. If your not finding any blown fuses or bad relays it might very well be the PCM (Power train control module) itself that is going bad. A dealer will have to check that out for you.
