What code reader are you using. I say mice have been at the wiring.

If the temperature sensor in the thermostat has failed the car may not start due to incorrect mixture

The temperature sensor is located in the thermostat housing itself so a new thermostat is required I had one replaced at 60k miles due to the thermostat failing open. The sensor relays information to the ECU which in turn sets the fuel mixture according to engine temp. If you do decide to change it my advice is buy the genuine part from MB as I did pattern parts can lead to more problems

Thank you so much malcolm are they easy to remove and fit

They are reasonably accessible at the front of the engine but quite tricky to replace my advice is to use an independent MB specialist.
I think you need to have the car inspected by a trained MB technician before going ahead with any repair from what you’ve described it may be the thermostat/sensor…
