My 318 overheated about 3 weeks ago, i immideiatley took it to the garage who changed the thermostat.
After driving it for 3 weeks it appeared to be ok until I went on a long journey. It overheated again the tempreature gauge was on full. I had it towed back to home.
When I am driving it is ok, when in heavy traffic - when i am stoping and starting or moving slowly then it appears to overheat. No hot air come through the heaters in the car any more. I am driving it short distances at the moment and the tempreature seems fine.
I have tested the big fan in the engine with a piece of paper and can stop the fan - should this happen? I also checked the coolant level, I only toped this up a few days ago and more than half of the coolant had gone.
Has any one got any ideas what the problem could be? I am annoyed with the garage as I thouht they fixed the problem but obviously this is not the case.
I dont know much about card so any help would be gratefull.
