• question to @Fixedwheelnut (who I remember has been in touch with BMW) and other BMW users/experts, what would be the best engine for the E46 for petrol and diesel?
    Currently contemplating an E46 purchase for the next car, not looking for power at all just looking for best reliability in the E46 range?

  • Not fixedwheelnut, but his advice to me was N47 engines are crap and prone to problems.

    M47 more reliable. Swirl flap failure much more common on 6 cylinder (m57) vs 4 cylinder, and he said that he hadn't seen many m47 engines with swirl flap failure.

    Also, from what I've read, the manuals are more reliable than the autos.

    Happy to help
