C220 CDI "On my C220 CDI (2001 year) “Coolant-visit workshop”

[Greg62]

On my C220 CDI (2001 year) I’ve got a message “Coolant-visit workshop”
When I start engine immediately engine cooling fan is starting but the engine temperature is low and is looking like temperature sensor is working fine but the engine has no power, I can’t accelerate.
I’ve check the coolant in the reservoir and the level it’s seems to be ok.
Any ideas ?

Put it this way, if it's anything like my car it sounds like it's gonna take off!
