Steering wheel shift buttons sensetivity

[Egroeg80]

Hi all. 

New owner of a Q4-Etron. 

One irritating quirk both my wife and I have noticed is the mobile phone button on the right hand side of the steering wheel. It's ever so easy to accidentally press and buy doing so it auto dials your last interacted number. There appears no method to disable this button which sits on the very crest of the steering wheel bezel (hence easy to press with your palm). As its a soft button, it doesn't even need to click for you to activate it so I'm now adjusting the active hold position on the steering wheel which is nothing short of irritating. 

Suggestions or thoughts appreciated.
