The temperature gauge in my S220 Cdi 2.2 OM651 started to have difficulty reaching normal working temperature; often now moving from 60c, especially if the heater is switched on.
I also noticed that the ECO light goes Orange when the heater is switched on, but stays green with the heater off even when there is no difference in the temperature.
I am assuming that it is the thermostat.
However I put the Icarsoft scanner on it and I also noticed that there is a fault code 53336/6058.
Y85 Exhaust Gas Recirculation Cooler Bypass Switch Over.
I noticed this fault number a couple of months ago but forgot completely about it as it does not seem to be causing any noticeable problems.
From the attachment below (PAGE 32 and 33) I assume that this is actuated by vacuum.
However, if the temperature of the incoming exhaust gas is too low, the path to the EGR cooler is closed via a bypass flap and the exhaust gas is guided directly to the charge air manifold. The switchover valve for the bypass flap is controlled by a vacuum unit.

Anybody experience this?
