Mercedes C300 petrol Hybrid 2015 - Tomski - 28-07-2022
Hi
Did anyone of you encounter this issue
If vehicle is driven for longer driver lets say 10-15km no faults
But if car is driven for 1-2km after 1-2 days there is faulty for P012800 The coolant temperature is below the coolant thermostat specified temperature.
I seen this fault multiple times every time in turned out to be faulty thermostat fitted Dealer part and problem solved but on this specific car problem persists.
Carried out test for thermostat in xentry and it seems to pass every time
Any advice would be welcome
