#294 of 305 Do I need a new battery? by homerkc

Oct 30, 2012 (5:26 am)

I have a 6 yr old Jetta (2.5) w/orig battery and noticed the battery cranking the car a little more slowly lately. The last two mornings, the Steering, EPC, ABS and Brake lights have stayed on. Since everything seemed to work (brakes!), I drove slowly away. Yesterday, they went out after a couple of minutes. This morning, I stopped the car after a half mile to read the manual again. After restarting the car, all of the lights went out and it drove fine. Could the battery be failing, or is it something more like the computer module?

At 6 years old, your battery is on borrowed time. I would replace it. Sometimes cars act strangely when the battery becomes weak. For example, my 2006 Ford Explorer acted as follows: when starting up, the air bag light would stay on (rather than turning off after a few seconds). Once you drove the car a mile or two, if you stopped and then restarted (such as when doing errands), the air bag light would then go off normally. This seemed to act this way every morning, after the car sat idle for 10-12 hours. I thought the air bag was defective, but in checking lots of sources on the internet, I found out that for this car (and other Fords), if the battery was a little weak, apparently the air bag sensor would malfunction. I replaced the battery, and the problem was gone.
 
You are going to need a new battery anyhow, based on its age, so I would give that a try first, and see if you problems fix themselves.

#298 of 305 Left Turn Signal interferes with Automatic Shift Lock by scubaneo13

Dec 11, 2011 (12:20 pm)

Just recently after a rain storm my 2003 Jetta 2.0L GL has been acting up. When I switch on the left turn signal, the (ASL) Automatic Shift Lock starts engaging/disengaging with the rhythm of the turn signal indicator. The left tail light flashes normally, but the reverse light glows a little as well. Now, with the left turn signal on and when I press on the brake at the same time, the turn signal indicator flashes faster, along with the ASL solenoid engaging/disengaging at the same rhythm of the faster turn signal indicator and my tail light does some crazy light show with all the bulbs on the left tail light flashing. Note: None of these problems occur with the right turn signal. Also, the same issue occurs when I activate the hazards. So somewhere I have a crossed circuit, but I have no idea where. Is there a particular relay where these two circuits meet that could be malfunctioning? Since it's messing with all the bulbs in the tail light, I'm thinking its a wire connector somewhere that got wet or something of the sort. I have torn apart a small portion of my dashboard underneath the steering column to get to the wiring harness's and other hidden relays. Does anyone possibly have a solution or a place for me to start checking to resolve this issue?

Obviously a bad ground connection somewhere.
 
If it were my vehicle, I would clean-up EVERY ground connection I could find.
 
By "clean up" I mean
1) Remove screw holding down the wire-terminator
2) use Dremel-tool to bare the metal where the connection is made
3) Also use Dremel to clean up the termination itself
4) Solder the wire to the termination.
5) Reassemble
 
Since I have the shop manual for the 2003 Jetta, I have the advantage of knowing where all the ground-connections are as well as all the electrical schematics. With some studying, I could isolate the problem to the specific connector which is the issue.
