Knocking Noise from Rear

Can anyone help with trying to diagnose a knocking sound from the rear axle?which gets worse when i have passengers in the back. Audi main dealers replaced both rear shocks but this made no difference!
 
Check your rear springs are firmly seated. If it was taunton audi you went to chances are the replaced the first thing they could think of with out checking. where abouts in somerset are you?
 
Wait for you anti-roll bar to go walkabout then you can have synchonized knocking from both ends!!

Seriously, it could easily be something as simple as a loose/worn exhaust mounting causing the exhaust to knock against the underbody over bad bumps. Don't expect a dealer to identify the simple or obvious - there is no profit in it!

As we are guessing, what about the rear booth lid, they seem to be getting a bit of play ove time

If you open the booth you see on the lid two rubbers - like a wedge (one each on each side) loosen these with a torx bit and push them inwards, so when you close the booth it ties better in. this should reduce the play in the booth and close the booth titer
