I've had the Mk111 Superb SE Business Combi for about a month now. Great car - comfortable, huge, 50mpg+ average. 

One massive annoyance is a buzzing/resonance from the central dashboard area around where the nav screen sits when I accelerate. Sometimes if you press on the screen surround in the right place it goes away. Driving me potty - anyone noticed this, or better yet, come up with a fix? Thanks!

I guess no one's suffering from the same resonance! I'm weighing up the size of the annoyance of the buzz against going to the dealer and having them tell me 'that's normal' or somesuch other excuse.

I had this on one of the demo cars i drove. Think it was on NickH's thread so take a look at the comments.
