Brand new Audi S3 with rear suspension noise
 

I have a brand new (700klm) Audi s 3 ( magnetic ride ) .
I noticed within the first 10 klms a dull knock or thumping sound from the rear suspension.
After returning the car a week later the technicians said occasionally the rear suspension bushes are bad from new ( or wrong ) and they need replacing.
He did say that the new replacements may not completely fix this too .( although it will be improved obviously)

Anyone else aware of the problem i am having with the S3?

I just hope after its been fixed-i never hear the sound ever again.
