Ive had a 2000 328i for about two years now, and when i bought it, it was running great with about 85000 miles. Recently, i have been having a number of problems and dont know where to start. I grew up working on old chevy's, and have never had problems like this before. First of all, there is this horrible screeching sound that comes from the back of the car whenever i accelerate, or more like a chirping sound, not a loud solid screech, but a bunch of short ones. Now, the front of the car makes sort of a rubbing/grinding/clicking sound from the drivers side wheel, only when i turn to the left. Finally, my car overheats, SOMETIMES!. Usually at stop lights, it will over heat, and now the a/c is not coming out cold either. At an idle, the car overheats as well, so i figured out that the cooling fan isnt kicking in when it needs to, so might that be a relay or the thermostat? Please help, im a first time bimmer owner, and ive always wanted one and love my car, i know after some tlc, itll be running smooth again.
About the overheating: it seems like your electric auxiliary fan is not coming on. This may be because the temperature switch that activates it is faulty, or because the fan itself or the relays are the culprit. Have you checked the fuses? A couple of the fuses (or at least one, I know for sure) affects both the A/C and the electric fan. If this fuse is out, you would not get any action from the electric fan, and your A/C would not blow cold at all.
I have no idea about the screeching sound from the rear of the car. Perhaps wheel bearings? Maybe your brakes are worn?
When you turn left, your tire may be rubbing against the wheel well cover, if the cover is lose or sagging. ell us more about the noise. Does it change with the engine RPM? Is is accompanied by any vibrations or the car or the steering wheel?
Best of luck with all this.
Check back again, as some other people have a better understanding of these matters than me.
Cool thanks, ill check the fuses, that never crossed my mind. as far as the screeching sound, rotors and pads are good, and i was thinking the wheel bearings as well, but it does not make the sound in revers. And as for the weird sound when turning left, it sounds like a bushing or something is bad, the wheel clears the well and everything else fine. thanks again, i reallly appreciate the help.
