Here's an overview.

I have a 2003 S8 with the NAV system (not the NAV system with the display in the radio - the version of NAV that has the information displayed in the little screen between the tach and the speedometer).

This system is controlled by a few buttons and a dial in the center console - in the area where the front cupholder is located in A/S8's without the NAV system.

In normal operation, you spin the dial to select different options (or letters if you are spelling out the name of a town/city/street etc) on the NAV display, and press the dial to select the highlighted option/letter.

My dial seems to have a mind of it's own, because it selects options/letters on it's own without the dial being pressed.

The only additional piece of info I have been able to collect is that the dial never selects something without me having spun the dial - most times it selects whatever option/letter is highlighted after three clicks of the dial left/right. If I don't spin the dial at all, it seems to be content where it is at and does not select anything on it's own.

This interface also controls an in-dash menu which is used to enable/disable the tire pressure monitoring system and other miscellaneous features - this behaves in much the same way, so the problem is not unique to the NAV system but instead unique to the interface in the cupholder.

I hooked up my VAG-COM, ran an auto-scan, and did not detect any error codes.

Any ideas?

sounds like a bad switch to me... the whole thing pops right out and is around $100 @ the dealer

Is there a trick of some kind, or do I just need to pull harder, perhaps with the assistance of a screwdriver at the bottom of the box to help pry it upwards?

A8CT

exactly, just pry and pull, there are no hidden fasteners, just friction fit

Hit the **** with some contact cleaner. Something musta spilled from the cup holder. Poor design.

Tried contact cleaner this evening - no luck

For example I can't change the clock because the dial skips over the menu option. It moves and then when it gets to a particular option it does nothing for that one click, then the next click moves on to the next option, skipping the one. Any ideas?
