Hi I have a 2016 gts last week I went to start the car, and a message appears oil coolant malfunction.checked the manual and it says transmission coolant pump faulty. Had a new pump fitted,not by mercedes but by an independent garage.trouble is they cannot clear message. Car is running fine oil temperature is good so is coolant. They have been in touch with mercedes and they said check electrical but still can't clear it
