Why does my 328 sound like a pussy
It makes this weird loud whining noise that is clearly heard when I have the radio off and the windows down, and it must be audible to anyone standing near my car when I start driving. It becomes a higher pitched whining noise as I accelerate but you can't really notice it at higher speeds most likely due to the road noise. It pretty much sounds like an electric car, much like the noise a remote control toy car makes when its moving. Needless to say it bothers me a lot that my car sounds like a big pussy. Anyone else's e90's sound like this? Any ideas what it could be.

It might just be worthwhile to take it to a BMW specialist indy shop to have the whole car inspected, with close attention paid towards to the whining noise. If the noise is as audible as you describe then I'm sure that they'll be able to pinpoint the issue. |

I've had a very faint whistle/hiss/whine since I got mine in October that I've finally pinpointed to the power steering system somewhere (about 90% sure). Most people that ride in the car don't notice it even if I point it out, but its driving me crazy.
Last month I thought it was getting louder, after a few weeks it got ridiculous, loud whine eventually joined with metallic ticking noise (not lifters) Turned out the alternator was toast. Replaced the alternator pulley with a new one first which did precisely nothing; found a brand new (not reman) Bosch 180 amp for $413 shipped on Amazon. They are back up to $480 now for some reason so I guess I lucked out. Definitely check the alternator. If you load it down and still see 15.1+ volts, you're probably having the same issue I was. By chance has your factory battery been replaced, and if so was it registered/programmed? Just curious. |

Invest in one of these. You can at least rule stuff out easily with it. I got the $4 one from harbor freight, it works but unless your head resembles a giant cucumber it won't fit well at all. http://www.autozone.com/tools-and-eq...ope/70131_0_0/ |

I think its one of those deals where if there is an issue with either of the other components they suggested you replace, it will just destroy the compressor. But definitely don't take my word; hopefully someone that knows more about the climate control can chime in because I'd like to know as well. Keep us posted on how this turns out please. |
