Hi
118 D 2014
I have been having coolant issues for the last couple of months. Dash light come telling me low coolant got it topped up two late dash came on again saying the same topped it up again.
Called my mechanic he carried out a pressure test head gasket test and water pump check all good. That was about a month ago yesterday dash came on again say low coolant. No leaks have been found. The car does 15 miles a day.
Any ideas
Regards
