Just because it is in "bently" doesn't make it correct!
Just because it is posted here doesn't make it correct either!
But "N65/1 is the module that controls the electric COOLING fan".
Air injection on a 1996 C280 is done thru the HFM computer (N3/4) & a simple relay at position "B" in the fuse box.

Air injection needs to have a perfect front O2 sensor to run it's test & engine temp above 80C.
