Try the oil level sensor. Common issue.

Your BMW uses a blower motor resistor to control the speed. It is located on the passenger side of the heater/ac case near the firewall. If you are laying in the passenger front floor and look to the left and approximately 4 inches from the firewall and 2 inches above the carpet, you should see a connector with five wires. The resistor is held in the heater box by a plastic tab about a inch long. depress the tab downward and remove the blower resistor.

The belt that broke is the alternator drive belt,it also drives the water pump& the power steering pump which is why the engine overheated &steering went heavy.Hope this helps.

need to communicate with the convertible top computer. Need dealer level diagnostics

If the battery is under the back seat like some models, charge battery.

There is a fuse box under the hood on the driver side near the strut tower and one behind the glove box.

depending vehicle model some get it down the wheels some by gearbox

check ews manupulation fault code use scanner

that can be caused by transmission wrong gear selection or transmission solenoid errors or catalic convertor or egr system stuck open mixing oxygen with carbonmonoxide excessive

I am guessing the check engine light is on. Scan it with a code reader ($20). You didn't mention what year your car is but most bmws have a 100,000 mile spark plug life span. If you have a misfire code then swap the ignition coil to a different location. Misfire is on cylinder 1 swap the coil to cylinder 4. If you now have a misfire code on cylinder 4 then replace the faulty coil. If you have lean mixture codes check for large cracks in your intake air boots. The oil separator hose also causes a large vacuum leak along with the more expensive vacuum regulator.

dealer only i would imagine,if original vehicle then no problem but i suspect that your vehicle has a add on boy racer alarm fitted .

You have to take it to BMW . They need to go into computer with scan tool an tell the computer that battery was changed
