#254 of 314 Flickering Problem..
Nov 22, 2011 (6:59 pm)
Hello, I have a 2005 VW Jetta 2.5. I just bought the car two weeks ago and am trying to work through the few kinks it has. I am trying to diagnose the reason my climatronic system is acting the way it is. The temperature read-outs do not display and the lights do not light up, most of the time. It will then be noticeably flickering if you turn the headlights on and drive around. It seems that as the two weeks have gone on, the flickering has happened more often and just tonight, the temperatures started to display. I have no idea what is going on. I thought it was a faulty climatronic unit, until this happened tonight.
I believe it is likely some kind of electrical wiring issue or something. My headlights and overhead lights will occasionally get dim and then light back up to the original brightness. Also, for no explainable reason, once I turn the car OFF and have taken the key out, I can still click the power button on the factory radio unit and it turns on and plays just like the key were in.. Ideas?? I'm in desperate need of some help here!
Thanks in advance!

The flickering lights/gauges that light or don't light sound like the voltage regulator is bad. I had a VW that did the same thing, whereby the headlights would dim, then get brighter, then dim etc. It actually burned out the headlights a couple of times.
Have your favorite mechanic do a thorough electrical system check on the car.
As for the radio, VW's used to wire the radios so they would be operational even when the car is off. I would either check you owner's manual on the radio operation, or the "accessory" setting function when you have the key in the ignition, but only turned one "click" so accessories will operate. It may tell you under what conditions the radio will operate. If you can't find any information, check with a service department at a VW dealer.
Hope you enjoy your Jetta. Our family has 2 Jettas, and we thoroughly enjoy each one!

I am having some of the same issues as well. I too have a 97 Jetta GL and my power locks aren't working proper, I tried replacing ALL the fuses but it didn't help. I would try to take the door panel off and see if you can't find an issue.

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
