4 cooling system problems with this car---Thermostat 1 week after purchase.
Next was the plastic impeller piece of junk Water Pump.
Then the Aux Fan circuit blew.
Then most recently the radiator cracked.
Will not buy another BMW, I spent more on repairs for this car than I did for routine maintenance on the Lexus in 4 years of owning the Lexus. I miss that car...
The handling is great, fuel economy very good, but the problems with the cooling system offset any real enjoyment that I could have had with this car. I barely trust it to take me to/from work and not much else.
Mate, do yourself a favour-get on top of the cooling system problems-replace the water pump with the one that has the steel impeller, replace ALL hoses and the head gasket-bleed the entire cooling system-be assured, the cooling system problems WON'T come back.
Then, and only then, will you have peace of mind-the car should be very reliable from thereon in.
Go buy a lexus then
