Evening all,

Hoping some among you may have some info on potential issues/things I can check based on what I'm experiencing lately.

2014, F10 520D, auto with B47 engine (~150k miles)

In the past 2 weeks I've noticed a vibration sound when the car is stationary and I put it into gear.

When stationary and I put the gearbox into D, a vibration sound commences from what appears to be the engine bay area. If it returns it to P, it goes away. Doesn't happen in R.

When I pull away it disappears, returning momentarily when the revs pass 1500 rpm (only at this point in the rpm range, not before or after) or when I come to a standstill again.

There is a (very) small pulse through the car when the gearbox is initially put into gear, like the full extent of the drivetrain has been engaged - I think that's has always been there, but mentioning it in case I've normalised it and it's a potential symptom.

If there's any collective knowledge out there on what would be worth checking, or if this sounds similar to what someone has already experienced, I'd welcome your inputs
