Someone rigged up what looks to be an aftermarket electric aux fan in front of the radiator on my 220D parts car. It has a sensor for coolant temp and a relay (presumably to turn the fan off and on). I have never tested this thing, but it's yours for the cost of shipping if you want it. I hate to throw any more away than I have to on the pars car. If you'd like, I can fiddle with it and see if 12 volts gets it running, if it's quiet, etc...
