My 2013 500i UXV runs great but recently check engine light is coming on intermittently then the heat sensor comes on then stops. Note: The radiator fan is working. Has anyone cleaned the outside radiator so air can breath through radiator coils? That's my first plan of action. If anyone can suggest other options for me to check much appreciated. Note, I put in 50/50 antifreeze last year and drove over 500 miles with zero overheating issues. Even put to 100 miles in one day.
Thanks in advance!
