 I'm new and have a mini problem!
I'm new to mini forum, I have a problem with minioverheating and loss of power. My mini one 07, had the coolant exchange replaced twice, the second time the leak stopped but has been continually showing me overheating symbol. The car has been in and out of garage, coolant drained, and replaced and then the heating stopped working, the garage said it was an air lock. My question is if it has been drained and pressure tested why is it still overheating. I am now concernd after reading some of these threads that there could be something wrong with the head gasket! I really just want my car back and feel safe to do it an stop continually taking back to the garage!!! Any help/suggestions would be greatly received. |
