car is in mint cond, everything works
Hope you are able to help me here, don't know if this is an air lock.
Here is my problem, my car overheated, I took the car to the bmw garage where they replaced:
The thermostat and thermostat housing
Few weeks later car over heated again, this time same garage done the following:
Pressure tested the cooling system, car passed this twice
They also done a block test which the car passed
They bled the cooling system and all was ok again for a few weeks.
Now the car has overheated again and I can't seem to find out what is going on.
I just seem to have loads of air in the system, has anyone else had this issue?
