Clunking sound from rear on light to medium bumps
 

I've got a 2SS A8, I got 5000 miles so far. I've noticed a clunking sound coming from the passenger rear suspension area., usually over rough roads and light bumps.
Any ideas or any have experienced the same.

I have uploaded a video. Sorry for the quality.

I have a 2SS A8 convertible with 6,000 miles that just started doing a similar thing. Mine also seems to do it when the car "twists" turning up or down an incline at an angle. The weather has gotten colder so I wonder if that has has something to do with it. Will probably try to look at it after the holidays.

Thanks, sent you a PM.

I noticed this on mine duing a "twist" like Marks... Im now on aFe coils so Im sure ill have to resolve this myself..

Check the swaybar brackets.

I have uploded a new VID which is much better from the previous one.

The car is at the service now.

Got the car back and its fixed,

they have removed and re-fixed the rear wheel parking brake shoe.

Thanks for posting this G. Edwan. My 2SS convertible developed the same noise last Fall. I took it in to the dealer, but they couldn't reproduce. This will help provide the service department some insight when I take it again after I get it from storage (April 1st).

The issue is back with an added SQUEAKING sound :(

did they say what exactly they did to fix this?

Did the NSA take this down?

take the wheels off and torque the sway bar connections
