  1. Noise from transmission after clutch change

    General E46 Forum
    I replaced my flywheel, clutch and throw out bearing with the Valeo single mass conversion kit. Also replaced the pilot bearing. There's a noise/vibration coming from the transmission trough the shifter. It happens in neutral and while driving only when applying throttle. I could be coasting in...
  2. Engine noise, dieseling, could recent valve cover replacement be a factor?

    General E46 Forum
    Friends, I recently replaced the CVV, associated hoses, valve cover, and spark plugs. Shortly thereafter I noticed a new engine sound, sort of like a diesel engine. No dashboard lights, but it does seem to affect performance. My oil level sensor has never worked, but I check religiously...
  3. 2001 330ci Engine Noise

    General E46 Forum
    Hoping someone has heard this noise before and can help me diagnose it. It sounds like the old retractable antenna electric motors do when the cord breaks and they keep spinning. Thanks for the help! https://www.youtube.com/watch?v=um6sMjbXvtA_a_
  4. SMG strange noise

  5. Strange noise emitting when steering wheel is standstill

    General E46 Forum
    I am trying to identify the source of this noise when my steering is standstill, that is, when I am NOT turning the wheel. When I turn the steering wheel, ever so slightly, the noise is completely gone. Does anyone have any ideas what might be the cause of that? I am attaching a link to a video...
  6. Chirping noise coming from the engine compartment.

    General E46 Forum
    2003 BMW 330xi: This has started happening recently. Whenever I start the car (especially cold) there is a cricket-like chirping noise coming form the engine compartment. This noise confuses and concerns me because I put completely new belts, tensioners, and pulleys on the engine (back in mid...
  7. Buzzing/vibrating sound and feel through brake pedal

    Suspension & Braking
    Recently bought a 325ci it's a 2001 117k on the clock. The brakes make a buzzing/vibrating sound which you feel through the brake pedal when at low speeds coming to a stop. Spoke to Halfords and they said could be the rotors being warped although im not convinced (pretty sure front pads need...

  9. Loud thud while launching

    General E46 Forum
    Hi everybody, I tried launching my car pretty hard today (before this I've haven't pushed it while launching). Got the wheels to spin a bit, and while I was gaining traction back, the whole car started shaking violently--the gear stick was really vibrating--, and then I heard a loud thud at the...
  10. '02 325i making a new noise. YouTube vid included.

    General E46 Forum
    Hey all I think the "help a noob" tag is the most fitting for this one First time poster though have used the site a handful of times already. I had a quick search through the forums to try and find an answer to my question though there are a lot of posts about new weird noises so it was like...
  11. Spooky Whale Noises

    General E46 Forum
    When my 330ci starts after a few hours of non use, it makes a deep "whale" noise that lasts for about a second each time. It makes like 3-4 groans then continues normally. Very strange as it does not seem steering or speed dependent. Looked through the threads and I haven't found a satisfactory...
  12. Could this noise be a soft failing water pump?

    General E46 Forum

  13. Belt noise but no crank! E46 Won't start

    General E46 Forum
    https://www.youtube.com/watch?v=n1TbNdo9a_c My car stopped working while running it pretty hard on an empty highway. I was going pretty fast, took a tight turn and there was a dip. Because of the dip, I braked hard enough to not go spinning out, but not enough to lose my momentum. That's when...
  14. Lound Fan Noise - Mack Truck on acceleration

    General E46 Forum
    Hello So a while back I did some work on a fuel pump and needed to reset the codes. By accident (not knowing) I reset the codes while the car was on or had was in the ignition position. Afterwards I read I shouldn't have done that. Immediately after I noticed a whirring noise from the fan like...

  16. Need Help Identifying This Cold Start Noise (Solved: Starter Exploded)

    General E46 Forum
    Another day, another E46 issue. :D This one came out of nowhere. The cold start rattle (starts at 0:14) happens whether the DISA is plugged in or not. The rattling noise goes away after a few seconds. Is it the idler pulley? I can't tell where it's coming from. Any help would be greatly...
  17. My s54 is making a scary noise

    ///M3 Forum
    Hello my s54 is making a very odd noise. This noise comes on in about 3-5 minutes of driving. When the noise comes on I can make it go away if I turn the car off for about a minute but it will come back after a bit of driving. I had the VANOS system replaced with the Beisan system about 300miles...

    General E46 Forum

I need the original exhaust system so that the car runs smooth and without noise on a daily basis. My...
  20. ECU Fan Guidance

    General E46 Forum
    I have a quiet but annoying interior noise. Sound like crickets. On start up and sometimes while driving. I am convinced it's the ECU Fan (firewall near your left foot when driving). The noise isn't bad but if it's failing that's I presume a bad thing as I don't want my ECU to overheat. Has...
