M272 Thermostat Housing Sensor Connector
I had to replace my thermostat on my 2012 C300. The connector (engine harness side) that is plugged into it is completely shot. It must have been rubbing up against something and wore it down to almost nothing.
Does anyone know what the connector part number is so I can find a replacement?

Mercedes is usually good with printing the part #'s on all the parts.

It may be 0225451926. Look on your connector to double check.
