#174 of 314 Odd Radio behavior - 2010 TDI Sportwagen
Apr 12, 2010 (5:32 pm)
Two or three times now in the last several weeks when I've turned on the radio there is nothing on AM. Static from 550-1700. FM seems a bit fuzzy, but not sure. CD-plays fine, Sirius worked fine. Cycling the power on the radio did nothing. Worked fine the next time I started the car. Going in for first 10K here shortly, so will bring it up, but was wondering if anyone had had/heard of similar issues. (This is the non-nav system set up)
#175 of 314 2002 Passat- upper control arm pinch bolt
Apr 13, 2010 (6:52 am)
Hello All: I need to replace a bad right side front upper control arm. The nut on the pinch/clamp bolt came free easily, but it seems the bolt itself is completely frozen (eight winters of Minnesota road salt tend to do that). I've soaked the bolt with PB Blaster, tried turning the head of the bolt with a big ratchet, hit the threaded end with a hammer, and even heated the bolt with my MAPP torch (protected the rubber seal on the good rear bushing with a wet rag, of course). All to no avail. I've now wrapped the entire assembly with a small rag and it's been soaking in PB Blaster for several days...hoping for the best. Has anyone else found a good solution for this ugly problem? Appreciate any comments. vwdawg
#176 of 314 2002 Jetta Door Ajar
Apr 27, 2010 (5:41 pm)
The driver's door does not activate the door ajar panel light. All the other doors do. I need to find out what activates the door ajar indicator because none of the manuals I've looked through references it.

There are 3 micro-switches INSIDE the door mounted on the latch/lock mechanism. It is not uncommon for one of the micro-switches to become unsolderd from vibration. These These micro-switches are BURRIED inside the door and are not easy to access.
There are reams of information about this on the net if you do a search. Here is a link to detailed photos of the door interior.
#178 of 314 2005 Jetta 2.5 electrical issues on starting
May 27, 2010 (3:33 pm)
Jetta has about 52k miles on it, no problems and regular maintenance done. About a month ago it started to stutter a bit on starting and then the automatic window buttons would not work for ~30s. Then the radio started not working for same short period of time after starting. After 30s everything is fine. Just recently the clock started displaying completely wrong times and the "blackout" period on the door panel and radio last longer. I did just clean some oxidation off the + terminal on battery which had been there a while. But that cleaning did not change the symptoms. Any ideas? Thanks.

I have the same problem with my '97 jetta suddenly. did you ever get any reply or information on what to do? I cannot find any connection between these two systems on the electrical schematics, so I am at a loss for now.

If you have the same problem that I was having, the voltage regulator on your alternator is defective. When you accelerate, the charging voltage on the battery should not exceed 13 to 14 Volts. I was getting 22. One way to confirm that it is the regulator would be to turn on all your heated seats and anything that is electrical inside the car. Now if the dash lights and radio remain on, you need a regulator for your alternator. I did not want to take a chance so I replaced the alternator. Everything works fine now.
Hope this helps.
If you are able to disassemble the regulator, it is worth a try to just order that. but that would be your decision
