Auxilary heater C220 CDI

[ziggy]

Does anyone know of/ or is aware of problems of failure of Auxilary heater. This is the heater that's supposed to warm engin coolant if its below 8 degrees C, found under the front drivers side wing.

The previous owner said you are supposed to hear it when it kicks in! I definetly can't hear anything.

Any ideas anyone?

Cheers

Mine can be heard very faintly just after the engine is switched off, it sounds like a slight whistling noise (jet engine - ish?).

Don't forget when the switch is red the heater is off.

I've found it does warm the interior of the car much faster when switched on.

Thanks for response. How much quicker? Still takes heater 5-10 to warm up first thing on these cold mornings. Is that normal?

Yes - the car certainly doesn't feel warm for at least 3-4 minutes, and then takes a little while longer to warm through completely. I do have an estate though and don't keep the load cover closed.

Many thanks for that Rich, I can sleep well now I've aquired my new MB electronically heated thermals that glow in the night, good old German realiability!
