When there is a bassy section of music the whole speaker vibrates on the rear parcel shelf (drivers side - RHD car). If I put some pressure on the speaker it stops. I Googled this and found a few others with the same issue apart they have B&O systems. I have the standard speakers in my car.

I emailed my local dealer who said they have not heard of this issue. They said it would be £96 to just look at the issue as the car is 2 months out of warranty. Pretty pissed off at that.

Is this a common issue or not? It's looking like I might need to take this to an audio specialist to sort out at a cheaper price that Audi will even look at it.
