This has been answered several times in the past. Proper use of the "search" function would isolate the answers.
For your convenience, I will summarize here:
The microSwitches inside the doors tend to wear out and start sending false signals to the computer. (ie... The door is OPEN and CLOSED at the same time, -or- the door is LOCKED and UNLOCKED at the same time... etc) The computer can respond in unexpected ways.
The proper "fix" is to tear into the door and replace either the individual switch or the entire circuit-board contaqining all the switches.
Personally, when my wife took her Jetta in to the dealer and found out it would be several hundred dollars to "fix", she decided to use the key in the door instead of the remote from now on. Hence far, using the key in the door has been able to lock-n-arm the alarm for her.
If you wish to tackle the problem yourself, there are several websites with step-by-step photos showing how to tear door apart and replace the $7 switches.
BTW: I know for a fact that the problems with my wife's Jetta started the day after the window was left open during a downpour. Apparently, water got into the 'wrong' place and has been a problem ever since.

Jetta 2011 TDI... since it has gotten colder on the east coast, when I leave my Jetta out at night, the driving lights will turn on at some time during the night. IF I park it in an enclosed garage, they don't. VW Princeton updated the computer, but nothing has changed. Still in need of a mechanic or exorcist.

You're not alone. My wife's 2011 TDI does the exact same thing (four times now). She parks it outside at work and luckily it's started every time...so far.

Hey caneel and creepylights: Every time I read another forum article about VW and Audi electrical "phantoms", I can feel my blood pressure and pulse increase. With all the supposedly wonderful Teutonic engineering that VW and Audi brag about, you would think that they could build systems that don't act in such a bizarre fashion. For a 2011 Jetta to have this issue is completely inexcusable, and for a dealer to NOT have an instant fix is even more egregious. I would go back to that dealer and DEMAND in no uncertain terms that they take this car and keep it until it's fixed, and give you a NICE loaner to use during the time they have it. I have owned five V-dubs and two Audis, and except for my 2005 Jetta TDI wagon, they have all had various combinations of power window failures, check engine light issues, oil pressure issues (make sure you use VW 502.00 spec synthetic!!!), wheel bearing problems, door latch "self-lock" phantoms, and other annoying issues. The positive thing...they just seem to keep on running, which I guess explains why, in a recent fit of temporary insanity, I just purchased a near-mint 2003 A6 Avant Quattro w/ 71k in Arizona. And I DO love it...at least for now. Good luck! vwdawg/audiphile1

Noticed that when I was in Maine this past weekend (very cold) and the car was outside, the phantom lights came on. Back in NJ, in my garage, they did not. Hmmm...

Obviously - your car is not certified to be in Maine - LOL

Our '02 Jetta started acting possessed about a month ago. First, the "door open" indicator kept turning on while the car was in motion even when all doors and trunk were shut securely. It comes on and off several times a minute. If you shove the driver's door with your elbow, it'll turn off temporarily. Next, the power to the cd player/radio started turning on and off randomly. Using the turn signals seems to make it worse. Now the car alarm goes off at random times while the car is stationary and off. It just went off a moment ago while sitting in my driveway, even though it has been hours since we drove it. Today the car stopped consistently responding to the key remote too. Sometimes it locks the car, sometimes it doesn't. What on earth is going on??!

My wife took a video of the car with the lights on and then showing that the car was locked and the switch was off. She brought the video and the car to the dealer. After watching the video, they gave her an Audi to drive while they fixed her car. When she picked it up they said that four more people had contacted them about a similar problem. They replaced the light switch and she asked if that was really the fix or just a starting point they had nothing to say. It's warm today so we'll have to wait and see.

Not an uncommon problem.
The microswitches in the door are starting to get flakey. To fix, the door needs to be torn apart and parts replaced.
BTW: When my wife found out how much it would cost to 'fix' her 2003 Jetta, she opted to NOT get it fixed. DOWNSIDE.... the alarm and keyfob is also affected. (Cannot lock doors with keyfob...must use key in door)

A little to late and missed to help you, but maybe some one else will like to have a professional answer. The problem you were having was the ignition switch. The steering wheel must come off along with the air bag and use a bearing puller to pull off a sleeve to get out the blinker switch mechanizm. Once out and placed on a bench there is a little screw that holds the switch into place. Change the switch and your back on the road. I hot wired the starter for a year before i took my precious time to do the job. After enough teasing it became an obsession. Just another hill to climb waiting for the next problem like the transmission shifting great, then out of the blue it dont like over drive or even some times third gear, shut the car off and back to brand new, change the transmission speed sensors, make sure all wiring isall up to par with no corrosion or bare wiring. Great car once your past the gremlins.
