My Ride: 2009 BMW 528i
![Lightbulb](https://5series.net/forums/images/icons/icon3.gif)
Hey there, i have a 2009 528i, so, 3 months ago i had an accident, my bad because i didn't have insurance at the time, so i spend all my time repairing my car which was a succesful.
The thing is that my friend once time ago tried to jump my car and i didn't realize he put the wires backwards, so, it burned my alternator and ABS module, i changed both of them, and soon i'll reset ABS lights.
But now i wanna know something about the title, if its normal to that happens, i also changed the thermostat because the old one got broken on the accident, so i installed the new, no leaks fortunatelly, and check the water pump which is also good because i heard it pumping the coolant, so any ideas?
Checking the KTMP-MOM before bleeding and before realized the coolant level sensor was disconnected by me always like 80-90 degress on a normal drive arround my hood, after bleeding and putting back the sensor the start temps are between 45-55 degress (in celsius well), i drove a short distance and rev up the engine, it didn't surpass 75 degress, is that normal?

The fan at max speed is not normal. Need to read the codes to see what part is causing it. If you don't have a BMW specific reader you'll need it to troubleshoot this issue

Update, I found there was 2 fuses from the fan missing, but when my friend put the cables backwards I took a photo of all the fuses and I realize there wasn't there at the time and I'm sure at these time the fan wasn't loud, but yup, if there's any I can help once I solve that I'll let y'all know!
