whistle

  1. General E46 Forum
    So, a while back I noticed that I was getting a certain whine/whistle from my m3's engine bay while driving. The whistle only appears when using light throttle at speed, maintaining speed, or when going downhill. The whistle generally starts around 2500rpm and gets drowned out by the engine...

    My 2000 323i Sport Wagon is making a couple very strange whistle sounds. Here are the conditions for the first one: 1) It only happens in Drive - not Park or Neutral 2) It is not affected by the AC being on or off 3) It is only audible at low RPM (1200-2500) 4) It does not occur at idle 5) It...

    My Chevy Aveo 2005 has a what I like to describe as a whistle noise. Elimination process: Breaks- Check! Had test drives at the mechanic shop...it doesn't happen all of the time and it didn't happen while there. (Frustrating) It only happens while coasting or in neutral. It doesn't happen...

    I know I'm new to this forum and I don't want to get hate for not trying the search tool, so I'm going to go ahead and say that I have searched multiple times on different forums and can't seem to find something that fits my problem. When I am driving normally everything seems fine, but when i...

    Hey all - I've got an '04 E46 325i sedan, M54 5-spd. Recently I've been subjected to an annoying whistle that seems to rear it's ugly head during light throttle. I do have a K&N CAI installed and have checked both upper and lower intake tubes as well as the corresponding vacuum lines. No...

    Yes, another whistle thread. Been looking through and I've heard that a whistle could either be the idler tension pulley or the air intake boot, but it doesn't exactly sound like that. I came out from work tonight and heard it start to whistle as I got in the highway. It's extremely faint -...

    Starting this past Friday, my 2001 330i starting giving me issues. While driving, the engine would all of a sudden take a dump. RPMs would drop down, and the pedal would be unresponsive. I would have to completely let off the pedal, then slowing press the pedal to regain control and drive...

    I drive a 2001 e46 330i with 200 000km on the clock. About a year ago this whistle started but only on heavy acceleration up a hill, but 3 months ago it started to happen more often. The whistle is normally from 2500 rpm to 3200 rpm in all gears, but again only under heavy engine load. The noise...
  11. DIY: Do It Yourself
    After seeing all of these threads on people asking why their cars are making a whistling sound at high rpm or while driving, it got me wondering what has caused this and I did some research and found that it was the lower intake boot that gets old and starts to crack, letting in unfiltered air...

    Hi all. I've been using the forums as a non-posting member for a while now as a resource, so thanks to everyone who has taken the time to put up a crapload of amazing E46 information. I've got a 2000 323i, mostly stock except for a new Sachs suspension from BavAuto, a new Reverse gear (stupid...
