I have RRS FBH issue. I learnt that FBH (Webasto) automatically starts when outside temperature is below +5 (Celsius) and engine coolant temperature is below +77 C. Now the outside temperature is below +5 I noticed that FBH won't stop even the engine is running in 'normal temperature'.

I suspect the engine coolant will not reach normal temperature (even the engine temperature gauge shows pretty normal temperature).

Question: is there easy way to check engine/coolant temperature? E.g. Diagnostics from Dashbord? Maybe this is a thermostat or temperature censor issue.

thank you for help.
