I was driving my '06 DB9 (auto) around town today. I noticed some stumbling at idle when stopped at traffic lights (might be coil pack time), so I shifted from D to P at the lights to get a better feeling of the idle. At one light, I shifted from D to P twice. When I pressed D again, the car wouldn't move. I turned the ignition off and restarted, but when I pressed D I noticed that the button seemed to be stuck in...it didn't depress much.
Then I noticed an error message on the instrument panel. Frankly I don't remember exactly what it was, but it was something like "Repeated Gear Selection."
It was a bit stressful: I was in the center left-turn lane at a light leading into a shopping center, and traffic began to back up behind me. I called AAA and they told me they'd arrive in about 45 minutes.
I decided to try something. I still had the plastic pry tool in the car that I had used to remove the console recently, so I pried off the ski slope. I then reached behind and removed the connector from the D button. The button immediately popped out.
I then reattached the connector, started the car, and pressed D, and drove off into the shopping center.
No further problems for the rest of the day...except that stumble at idle.

 

Interesting. Glad you were able to self-serve the repair.

Stumbling at idle may be a weak/old battery.

 

Wow, kudos on your on the spot fix!!

 

"A bit stressful" My worst nightmare having the car break down in traffic.

Huzzah! to you for the quick thinking.
