By the way, Nippondenso-15C is the brand & model of my compressor.

Hope this helps.
ok, it seems as if this is probably the issue..
I just called my local MB dealer, and they confirmed it as the "speed sensor". This is causing the a/c clutch to disengage if the engine speed is "too high"
Not sure what that means...or is this sensor indicating another problem?
Or is it safe to assume the part is just "bad" and I need a new sensor?

If thats the case, MB quoted me a price of 200$ for the part, and id like to know if I can find it elsewhere for a little cheaper.

Anyone have any ideas as to where I could order one ?

Doing a google search was completely unfruitful, as all I was able to find was ABS speed sensors.
