Hi all I'm looking for some help I have a 2005 c270cdi and have a few problems with the cooling fan at first it was turning on random when engine was off I had it replaced with a new mercedes unit but still had the same problem on a visual look at wires all looks well so ecu was sent of for repair when it came back after repair the fan would run constant when the key was in the ignition car went to mercedes where they said the fan was faulty when I gave them the invoice number for the fan they called back and said no the fan is fine it's the SAMs unit that's faulty seams it was sending to much power to the ecu any way the fan is still blowing so Iv took the ecu out and sent it off for repair again but the problem is even with the ecu out the car the fan still runs when the key is in the ignition mercedes said this is a fail safe measure please help anyone I'm getting fed up and need this car running
