The heater in my 2012 W251 R350 blows nothing but unenthusiastic luke warm air at Maximum setting however the Aircon blows nice and cold. This is a recent change from previously working well in all states.
From reading various posts I flushed the coolant system firstly to no avail and then bought a Heater Control Valve as the next most likely culprit. Having spent a while researching where the valve is, I have drawn a blank on the R class. Easily found other models though !
Can anyone help in providing pictures / a manual entry or a link to show how to get to the valve oon the R class please !

Thanks for the links, but have to say I'm still baffled.

I am looking for the location of part A2722000031 which wasn't in either link.

Any pointers gratefully received.

Thanks.

Click to expand...

that's because its the correct way to do it

the cooling system isn't compromised the heater is a std part of the cooling system
it also doesn't go wrong in the summer

I think we see silly valves again because they want to push to individual locations...
