Hi guys, long story short... A small amount of sugary drink was spilt on the MMI buttons (the four around the knob). I can take the knob off by pulling it off but I don't know how to take the buttons off? Or if that's even possible? The car is going in to the Audi shop in a week or two so I could always ask them to clean it.
The button which is stuck is the one which is illuminated. It is very very difficult to press down.
