it shouldn't be tood bad. The battery has a plastic cover that snaps off, and you can easily see corrosion, which should be on the "+" terminal. The terminal should be red, the corrosion should be white to bluish crystals. Ignition coil is almost certainly unrelated, just something they replace because of VW recall. You'll have to take your car to a shop to get the CCA checked. The corrosion, if it is present, would definitely affect the amperage, but the amperage could still be low without their being corrosion. Hope this helps. It fixed my car like a charm. Good luck.
#186 of 314 97 VW Jetta GLS Security Problems
Jul 11, 2010 (7:28 am)
I inherited a 97 VW Jetta GLS and am experiencing problems with the security alarm going off.
I am still trying to pay off credit card debt from college, etc. and cannot afford to keep dumping money into the car unnecessarily and cannot afford a new one either.
One day last week my trunk light indicator showed my trunk was ajar when it was not, I checked it and still would not go out.
I drove it the same day then could not get my trunk to open using the button by the driver seat? So, I had to use the keys to open it.
Then I went to lock the car and the alarm system went off, I could not disengage it using the car door lock, so stood there until it went off by itself, but could not get car to start due to security system had locked engine.
I ended up having it towed (another bill I could not really afford) to dealer who advised me that I could use trunk lock to disengage the security system.
Ok, I did not have them diagnose car any further because I am broke, so I left and have been driving it since, but have not been locking my doors for each time I do I have same problem the alarm goes off and have to use the trunk key to turn it off.
I also have noticed that my clock resets itself each time I now start the car?
Is all of this related??? I know nothing about cars, which is another reason I have gotten into so much debt for I trusted several different auto repair places to keep my car running for I need it to keep my job.
Any ideas/help/advise would greatly be appreciated. Thank you.

You asked "Is all of this related???"
It sure sounds like it is related. The security system checks that all the doors, trunk and hood are latched before it will "arm". If the micro-switches on any of these are 'flakey', then the alarm system may not work properly.
For now, since you are on a low budget, the only recourse may be to not set the alarm.
I am concerned that your clock resets every time you start the engine. This suggests that the battery may have dirty connections or may be bad. A weak battery could cause ALL the other issues you are experiencing.
Many autoparts stores will check your battery for FREE. (Autozone.... etc)

I have a 2002 Jetta, 114K miles. I took it into the dealership and they are still trying to find out what is wrong. It started with the radio flickering on and off, then the dashboard info would reset (the time and trip mileage) on it's own. Then, the car's electrical would very quickly turn off and on and cause the dashboard info to restart and radio flicker off and on. Now, my car just turns off. I will be waiting at a light or waiting to turn and my car turns off. The engine is off but the auxillary is on, like when you turn the key one click. So I have to put it back in park, turn the key off then back on again and it starts right up. I have a new battery so it's not that. Not the starter or alternator. Luckily my car doesn't turn off while driving....yet. Also, I'll open my car door to get out and my alarm starts going off. The dashboard makes a clicking sound too after I turn it off while the key is in the ignition. Hopefully the dealership can replicate it and fix it as my normal mechanic and VW mechanic couldn't fix it and said i have to go to the dealer as it could be hte cluster.

#192 of 314 06 VW Jetta having door problems. Electrical? Sensors?
Aug 02, 2010 (11:36 am)
I have a 06 VW Jetta that is having a problem. I am getting the display on my dash saying that my driverside door is open when it is not. The door closes completely but it will not let me roll the windows down or set the alarm with the vehicle thinking the door is open. Any solutions
#193 of 314 96 jetta mystery
Aug 04, 2010 (11:26 am)
my 96 jetta has had the usual stall out when it rains problem and some dry wire or wd-40 has always worked. However, 3 weeks ago we had a big rain and though the car didn't do its usual stall after I parked for 20 minutes It wouldn't restart. the engine cranks. I took it to my mechanic who is very good with foreign and german cars. He said the spark was intermittent so changed the coil. Now all he gets is a 2-3 sec turn over and then it dies. He says he is baffled which for him to say is rare. He says the car is getting fuel. Anyone have any ideas, I'd like to get the car back...
#194 of 314 Jetta digital clock won't stop advancing
Aug 23, 2010 (5:25 pm)
On my 2002 Jetta 1.8T, the digital clock, hour digit, continues to advance, counting up to 12 and then starting over. Thinking the clock adjustment knob was stuck I tried turning it all directions to no avail. If I turn the right signal light on the clock stops advancing. As soon as the signal light is turned off the advancing continues. The clock continues to advance even after the car is turned off. On another forum with the similar problem the individual disconnected the battery and reconnected but no change. Any ideas?
