Hi i have a 2017 bmw 330e and the car has started making a revving/grinding noise when the petrol engine is running. The rev counter doesn’t move up and down.

There is a link to the video of the noise and the car is in Park and idling for the video.

Has anyone had this problem before or knows what could be causing it?


Thanks

Could be down to a faulty leaking injector. That would cause the revs to rise like that

Its in a garage at the moment and they replaced the vanos solenoid but the noise is still there. They haven’t been able to pinpoint the issue yet. The rev counter dial doesn’t go up and down with the noise. They don’t think it is the injectors and think it sounds like a rattling plate now? Thanks
