• E46 has started making a vibrating noise - like riding over a rumble strip - just before 2k revs. Any ideas?

  • Couldn't hear it too clearly, yours is a diesel isn't it? Check the air filter intake near the right headlamp where it slots in, the foam strip wears out causing a plastic to plastic resonation.

    To fix it lift it up and apply felt tape strips to the contact areas :)

  • Cheers - I’ll give it a look!

    I think you need to listen to the vid with headphones to stand a chance of hearing it, lol.
