Please help with this problem.
I have a 2000 540i and lately I been experiencing a problem with a sqeeling noise followed by oil level/pressure light flickering. After driving around 20 miles I get the sound then the light then I shut off the engine and get a check oil level on screen. The only thing I see is coolant spitting out of the expansion reservoir. What I'm thinking is the coolant is dripping on the belt making the noise and causing the belt to the alternator to slip causing a drop in voltage giving me the light. Is this feasable??
