Is this knock ?
Hi Guys
Have a 2014 F10 M5 with 18000mls and it recently started making this sound. Sounds like a knocking sound or something being loose. Took it to the dealer and they say its normal. Sounds suspiciously like rod know to me ? The car is stock standard,still under motorplan and not tracked etc https://youtu.be/7_7YwyYcjF4 https://youtu.be/oT402WTOJHU |

I had similar noises, it turned out to be timing chain issue. It’s at a BMW dealership being fixed.

Timing chain issue. Where do you get that. I want know?
This is normal noice and it’s not engine. Transmission oil line and pump sometimes makes that noice. Don’t worry. 👍🏻 |

I would suggest an engine oil flush, that's draining your old oil out and filling with special flushing oil and running at tick over ONLY,for 5 or so minutes then draining and refilling with 9.5 litres of Castrol 0-30 Edge together with the new o/filter(just what I use).
It should be fine but check the sealing security of your air filter enclosures and the air filters themselves if they're in good shape, the a/f enclosures are fiddly to screw back together and any unchecked gap could cause problems. Good luck. |

I heard it, video has gone now but if it is a pump pushing the ATF oil then there sure is a problem there with the racket it was making,it just wasn't right.Mine is silent as a lamb.

Does the noise change from when the car is first started for the day to when the engines up to temp? It's tough with a video to get the sound across, if there was an issue it sounds valve train related.

No ,the sound stays there regardless of whether its cold or on operating temp. I must add that the noise is only audible when stationary. If the you let of the brake and let the vehicle just "creep" forward the noise goes away. The moment you depress the brake again and stand still you can hear it again.
