    General E46 Forum
    Hello, so I bought a wrecked 330ci m54 and I'm rebuilding it. I put it all together and after some time of driving it, I noticed a rattling noise after 2k rpms. It does it both in neutral and drive. It definitely isnt the lifters. It's coming from the rear of the engine itself (towards the...

    General E46 Forum
    About three weeks ago my car started making a whistling sound. It sounded like a jet engine. At first it was RPM dependent. Only did it when around 1800-3000 rpms.
