Mercedes C250 CDI Coupe
C250 CDI Cooling / Radiator fan turning on when car switched off.
Hi all!
Not long had my coupe and have been browsing the forums until I have now encountered my first problem with the car.
Very simply, when I switch the ignition off, within a minute the engine cooling fan turns on to full and sounds like a jet turbine until the battery dies. The fan turns off when the ignition is turned on and the car drives and runs fine otherwise. Two garages have looked at it including a Mercedes specialist with STAR and neither know whats going. No codes, nothing. Battery has been load tested and is fine. The Merc specialist have recommended changing the fan unit so as to change the fan control module etc but they admit they are stabbing in the dark.
Any ideas? Getting desperate.
All comments welcome. Thanks.
