Default Rear driver side rattle when breaking/decel

Hey all

ever since I’ve got my car I’ve had this persistent and annoying rattle when decelerating or breaking at low speeds in the rear of the driver side

I’ve quite literally removed almost all interior trim panel in the trunk, wheel arch liner and a few panels of the underbody to find the source of this rattle… to no avail

this is the sound.. if anyone knows what it is, it would be of immense help

macan Gts 2023 for reference

Ours turned out to be the rear subframe. They installed a set of new bolts, torqued to spec and problem was solved. '23S for reference.

hey man, thanks for the reply

Was it the same type of noise under the same conditions (low speed braking and/or on decel)?

if so, that would be a good hint as I’m seeing service adviser today for a quick test drive

Exactly the same conditions. And it was a known issue they've seen before.

interesting to know, service guy acknowledged the issue but said he never heard it before

back to back tried with another Macan which didn’t have the issue

booked halfway through the month, fingers crossed they figured it out

I mentioned the subframe bolts but they shrugged it off, guess for good and bad reasons they don’t like to hear the client give suggestions
