A-Class

[barrowfordred]

I've had my A-Class a month now. I noticed recently that when I switch the engine off there is a humming noise comming from something still running. It does this even if I've only reversed the car out of the garage. Any ideas as to what it is?
Year 2000 A-Class.

MY ML55 does this, and i have been told it is a ancillary cooling circulation pump, for engine.
we also have a A Class 2001 A170 and i have not heard it on that.

A Class Humming

My A160 LWB Auto also hums to itself when the engine is turned off. It only lasts a few seconds and I think it is the cooling fan shutting down but I have not checked if this actually the situation yet. :idea:

My 160 does it and its 99 so I would not concern yourself to much about this. The car has not given my any problems at all and must do about 35plus and I have always found the a service £100 and the b service about £350 good value for money and no more than many other cars. I have had to replace two near side anti roll bars during the first 2-3 years but have had no repeat. I was told it was a common fault.
