Mercedes C180 Kompressor (2004)
Good evening all.

Could anyone point me in the right direction.

I have a C180 Kompressor, 140k covered. 2004.

The car is getting up to normal temp looking at the gauge on the instrument cluster. Yet i just seem to get no hot air at all. The fans are working fine up and down etc, but i just cant fathom the issue. Coolant has been changed recently as it looked old when i acquired it a few months back.

Any suggestions?
 
Was the heating working after the coolant change? It is possible there is an air lock in the heater matrix or the air blending flaps may have stuck.

Are there any clicking noises from the dashboard on start up?

Luke warm at best, no clicking noises i can hear.
 
If it was working fine before the coolant change, I think you probably have an air lock in the heater matrix.
 
If it was clicking you WOULD hear it. every time you switched the ignition on the noise is unmissable until the flap servos give up trying to home. Only happens when flap links are broken. Cheap to buy , very , very expensive to fit.

So u reckon its flap links?
What part no is that? If its too expensive a job, i may have to just live with it.

Its unlikely to be flap links, If were flap links the noise would have driven you potty by now. The whole dash has to come off to replace a few plastic links. It is so labour intensive that my MB indie had the fault on one of his courtesy cars (one he rarely wanted anyone to drive because of this) he told me it was not worth his workshop time to fix on this particular 2003/4 (ish) C180K old beater. I think it was scrapped in the end.
