Has anyone experienced a pop sound coming from the rear at low speed?
It sound like a small rock being pinched by a tire but it happens every drive.

If u push gas it clicks and if u push break it sometimes clicks also. Right?

I got similar thing which goes from rear and I havent found whats that.
Sometimes it irritates me during city drive.

Nope. I hear some "click" when I push gas pedal and when I release it.

Its like some small rock from rear inside of cabin. Idl whats thst mb something from trunk but its something from "car" not stuff I carry.

Its not noisy but its repeats everytime.

Yes I do

The exhaust is only do pops. A lot when you put in comfort and exhaust is closed.

Try it with low RPM at 2000-3000

Im not sure its the same noise mine sounds like a rock bouncing off a tire.
I'm thinking it may have to do with the exhaust flap actuator.

So after 1k miles I've noticed this too.

It's definitely not something coming from the exhaust, almost like a rock hitting the undercarriage under the trunk. It only happens at lower speed, when slowing down or driving in a parking lot.

This is my 5th bmw either M or with a m perf exhaust and I know what a burble, pop, etc sounds like coming from exhaust.

Has anyone asked their service rep about this?

I got the click sounds when I turn left, almost every turn.

I think its the spring somehow popping back into the seat. I get it on every left turn and only on the back right side.

Did yo u have this before and after the MSS springs?

[YolkyPalky]

Just to be clear, does everyone who has this sound has modified their car with aftermarket springs/suspension (MSS or other)?

This isn't happening to anyone with stock setup?

The OP stated in another thread it has nothing to do with MSS or other, but rather the stock setup.

Added: These threads are getting confusing bc we have people commenting on stock setups, on aftermarket threads and potentially the other way around. lol

Mine is stock and it happens almost every turn 😔

My dealer already changes the stabilizer rod in the rear and the sound was reduced. From ten turns only one was appeared.

If anyone has an idea where is the source of this knock, please don't hesitate

Thanks

I have a stock suspension, MY 2020, with the exact same pop sound coming from the rear axle. It happens when I turn right and left. I plan to have the dealer look at it next time I'm in for service and before I do the MSS spring upgrade later this year.
