Mercedes Benz C270 CDi 2001 - 0.9 amp current drain #

Posted by John Sartain on January 21, 2011, 8:07 pm

Year of Manufacture *: 2001
( Optional ) Engine Code or CC: 5 cyl diesel

Evening all
Tracing a current drain 0.9amp.
Fault code P1664 description electric heater booster.
Traced through heavy duty Fuse 6 to multifunction controller serving engine ecm and coolant heater.
I am suspecting coolant heater awkwardly located below inlet manifold/above starter which i cant get to without stripping out.
Can anyone please advise if i am following the route?
best regards

I think you are on the right track here.Done a few of these on the smaller diesel engines but are fairly awkward to disconnect as the main power lead spurs off the starter main cable.As you correctly say it sits in engine block ,just above starter.I have always left them disconnected with no adverse effect.May be quicker to drop down starter on this model.
