Has anyone on this thread gotten any good resolution on this issue since this was last discussed? This exact same issue as described by PunjabiM3 has started with my car in the last month or so, and it's startling whenever it happens. I can't quite believe it's normal, if it just started happening (my car has about 9,000 miles). If anyone has had a successful resolution, kindly pass along whatever your dealer did as I have an appointment with mine next week. Thank you all! Bill530e |

I have a feeling it the brake servo/vacuum pump. Only happens when the car sleeps and I primed the brake pedal before starting. Dealer is having issues replicating the issue.
I'll have to work on getting it on video before bringing into service next time.

I also have this problem. 2019 530i. Have it in the shop now but as of Friday they could not duplicate it. They have heard it though. Will update with any new findings.

Happens before you even touch the ignition button and can be quite a startling sound coming from a vehicle that's pretty much in all ways quieter and more refined than the F10. |

Shop gave up. Couldn’t reproduce the noise. Of course it happened to me on the way home . Gonna have to try and find out when it happens and try to be able to get it to do it on command.

I have this EXACT issue. Have about 3100 miles, has happened 3-4 times. Caught it once or twice on the dash cam, but the sound quality doesn't do it justice.
It CLEARLY has something to do with the brake, as if you time it right, it almost feels as if the ABS is going off - like a sudden severe priming of the ABS system. Unfortunately it its truly not reproducible. It has never been associated with any error. It also never happens during driving, so I assume just has something due to the many squeals, priming, pumps that occur when starting up. The next thing I'm going to do to reproduce is see if priming the brake pedal after the car is off whether that has anything to do with it. It's weird, loud, and doesn't sound right. But so intermittent how could one call it a 'problem'? Dealer said the same BS when I sent the video to them... that sounds like the fuel pump priming... Me: no it doesn't... |

I had the same issue in a 2015 535i with no cause found and no negative outcomes. This is not a new issue and seems inherent to the design of the car. I quit worrying about it and still heard it from time to time.

I've been getting this randomly, always catches me off guard and surprises me. Cannot put my finger on how to cause it though.

Add another to the list - Mine does this maybe every one time in 20+ after getting into the car. Has done since new.
The noise is jarring but it doesn't worry me at all. If it did it when the engine was running I might be concerned, but it only happens when the electronics are coming to life when I get in, and it just sounds like one of the electronic systems priming itself. Aside from the fact it occurs randomly, its actual behaviour when it does occur is consistent over the last 2 years and the car works flawlessly. |

On another thought. Does everybody who has this issue have the electric comfort seats? |

Hi all,
My electric comfort seat has now been disabled for over 7 weeks and the grinding has not occurred since. I am suspecting the electric seats. What is your thought? |
