I just bought my first BMW! I got it cheap but i'm sure it was at a price to pay to fix it.
The bimmer only has 110263 miles.
It was over heating and the transmission goes into failsafe mode.
I have replaced the coolant bottle, temp sensor and cap, while doing this i noticed red milky crap in the radiator. I am also changing the thermostat because some jack A** took the thermostat out and the car was giving a code P1622 because it wasn't there.
So i am thinking that the radiator has a leak in it and trans fluid is going into the radiator. While pulling out the radiator i noticed that there is only one hose that connects to the trans cooler.
So my question or questions are has any body had this problem and do i just change the radiator or is the leak in the actual transcooler under the car?
