Idle vibrations BMW X3, what to do ?

After the shop changed the engine mounts, valve gasket cover and fixed the oil pan leak (which involved the whole subframe to be removed), I have this annoying resonance/vibration at idle, but never in P or N or D, only when I switch to R, or if, when at idle, I rev the engine and let the revs come back down, there is a slight moment when I guess the revs fall or reach a certain RPM, when this vibration appears. So it is not related to the transmission but more with a vibration that appears at a certain rpm value, something begins to resonate, brrrrrrrrr like that under the driver side I feel.

Uploaded a video of this, but you need to crank the volume up or use headphones.

The idle is perfectly fine, it’s not rough, does not fluctuate and the car otherwise drives normally, nothing vibrates during driving, only at standstill, under the conditions described above.

What the hell could have happened, nobody has found anything, but surely something was not put back as it should after the repairs.

Oh, also, it goes away after driving for a bit, cannot be replicated by the time I get to the shop, so it drives me insane. Also, the EGR Cooler was replaced under recall at the same time, plus some seals at the rear differential and transfer box, but I don’t think it’s related.

Leave it at the shop overnight and have the shop guys feel the vibration that you are feeling.

Only way to diagnose this issue.
Unless CEL comes on.

I have something similar happen on my x3 but only in gear D…

I didn’t have anything changed like yours but it happens.

Getting used to it now… it’s not even a vibration. It’s more like engine feedback, engine rhythm feel coming from the drive floor, brake pedal, brake pedal area.

It’s a feel when you drive a 6speed or MT car and you bring the clutch to the bite point and it starts to vibrate type of vibration. It’s not even a vibration tbh. It’s a rhythm. I had a good buddy of mine drive my x3 and have him feel the brake pedal for this vibration.

He said he doesn’t even notice it. Until I brought it up to him…

And he drives a M3 and Range Rover autobiography. As well as a c400.

So I left it alone.

But if you really notice the vibration. Leave it at a shop and have them feel it in the morning or during cold start.
