VW Jetta Electrical Problems

    Hey Guys

    wondering if any mechanics out there can give me a lil help here,

    i've recently been told that my camshaft sensor on my 99 Jetta is shot, and my engine light keeps coming on.when we checked it on the computer it said "camshaft sensor A performance range".....?...... my mechanic said that it is emmiting a weak signal so it should be replaced, does this sound right to you mechanics out there?

    my mechanic has told me that it is $85 CDN for the part and its going to take him 3 hours worth of work, so its going to cost me a total of 370 CDN with taxes+labour.does this sound about right?

    this may seem like a dumb questions but how important is the camshaft sensor? am i paying to much or am i getting a deal here? i just wanna make sure that my mechanic is jerking me around.

    thanks for your help in advance

    Hey guys, I drive a 1999 Jetta, and the lighting has gone off that is behind the climate controls, so i can't see them at night.

    thanks in advance

    I'm having that same problem now with my 03 jetta; glad I'm not the only one. Does it always happen before the fan kicks on? It seems that way on mine, the ac, lights and radio will all turn off then back on. Anyone find the solution yet? :sick:

    My son bought a 97 Jetta a few months ago with 115000 miles. Runs good. a month later would not start. Starter burned up. Replaced. two weeks later same thing. Replaced again. Two weeks later same thing happened. mechanic perplexed. Tried another brand starter this time lasted over one month. Starter burned up again. There has to be something shorting it out. Mechanic said if it does not work this time, my son will have to take it to VW mechanic which will cost him $100 an hour. He can't afford that. Has anyone has this difficulty and maybe recommend something.
  • they probably stole your ECUM? if not check yur basics,batt.cables tight,ground solid,relays and fuses,these jettas are a anti -theft problem nightmare,windows roll down on thier own,hood release won,t work etc...join IATN network there a group of worldwide techs who have wonderful experiences with these autos plus others,i plan to scrap my jetta even though when it works it fun but the minor aggs aren,t worth it.
  • well, there are so many of you with these issues. but, welcome to the world of volkswagen. like said above, be sure to check the battery cables, clean them if needed, run a voltometer and see if you're getting atleast 12v to the battery. check the wires running from the alternator to the starter/cylinoid, that positive to the cylinoid, the negative to the block. when you put the positive cable back on if you haven't already found out, it'll reset all and your alarm will be annoying be sure you have you key fob or key around to disarm it afterwards. if all that is good and it wont turn still, pull your starter and take it to like autozone or something (for pre 97, oreilly's and autozone cant test it, take to napa or advance auto parts) to do it yourself, unplug the wire that runs from the cylinoid to the ignition switch (red/black)and touch the cylinoid to that spot with a rubber handled screw driver (be careful sparks will fly). okay so from there, if it works your problem is going to lie within your wiring or your ignition switch, most likely the switch. take off the negative battery cable, pull steering wheel, 2/3 jaw puller and vice grips to pull the splined adapter off, get the spring out, the ignition lock out, philips head to take out the current switch. replace it, hook everything back up. you should be golden. as for the alarm if you want to delete the alarm module, look for the diy use the search portal on vwvortex and search for the archived threads. if none of this helps, avoid going to the dealership and find a shop that specializes in european automobiles. good luck.
  • If someone has not replied yet, I just had my 97 Jetta fixed with a similar problem. It turned out to be the distributor. It's been driving great ever sense. :)
  • Hi all,

    Recently I purchased a 1999 Jetta through an auction. I am experiencing a problem with the alarm system. While the alarm is disengaged it will engage with a beep of the horn while driving down the road. I'm wondering if this could possibly be connected to the automatic door locks, as they dont work. Could it have something to do with the switch? I'm stumped and after reading some of the other issues I wonder what I've gotten myself into.

    alarm controller it behind the headlight switch
  • I am having problems reguarding my alarm system. It is sporadically going off for no apparent reason. I've tried resetting the alarm as well as cleaning the door latches. I've had no luck yet. I didn't know if there was a way to just disengage the alarm. My VW dealership said there was no way to do that and that I would just have to bring it in to get fixed but it just sounds like a way to suck more money out of me.I can do it myself if I only knew where to start. Any help would be much appreciated.
  • unplug the alrm controller
  • What might cause the key chime when the door open to stop working and also the interior light when key is removed form ignition to stop lighting up?

    '02 jetta 1.8T; which I've owned for five years now. When it was new, all the interior lights came on when a door was opened; then it went to a few lights, different ones and now maybe one light comes on when the door is opened. I did have the dealer look at it once, but didn't want to spend a ton on something intermittent. The bulbs and fuses are good. Is this another crazy VW computer problem?
    Speaking of fuses, does anyone know where you can find a cross reference to those fuse symbols? Very few are obvious to me what they stand for.
  • My 2003 GLS 1.8T has had the airbag warning lights on the dash lit up on and off for years. The Monsoon stereo has been replaced 4 times - about every 10 months it fries itself. 2 weeks ago, my Jetta was rear-ended by a cab in downtown Philadelphia and the insurance company has totalled it. I won't know what to do with myself now that I have a nice reliable Honda Civic SI and will not be constantly arguing with numerous VW service depts.
  • Well, I would sure give the Honda the TLC or "preventative maintenance" it needs sos the jetta junk dosen't come back about. But, remember [non-permissible content removed] happens, so any car could have brain wiring or sensor problems. Congrats on the new car.

  • my daughter's jetta alarm won't turn off. :confuse: Knowing nothing about alarms, we pulled the fuse for the horn, but that didn't stop it, we unhooked one of the wires to the battery and that stopped it for a few seconds and then it started again. Is there a way to completely disarm it? The driver's side door sets it off and she was getting in on the passenger side even though that was annoying, but now the lock on that side is broke. Any suggestions on how to completely disarm or at least how to make it work correctly? Thanks
  • We have a 97 jetta and the alarm won't turn off. Did you get yours fixed and if so how?
  • hey guys

    i have a 1999 Jetta, and whenever ig et out of the car and go to arm the door with the keyless entry, the car "honks" and arms but the drivers door latch doesnt go down, i have to press unlock then lock again for it to go down, i thought it might be the remote but i to lock it with the key and does the same thing

    anyone have this problem and possibly a solution for it

    any help is appreciated

  • I recently replaced the drivers side headlight in my 2001 VW Jetta GLS. In order to do so, I disconnected the battery. After I finished, I put everything back together and reconnected the battery. Since then, I cannot lock or unlock my doors with my key remote. Also, when I drive with the headlights on, there is a clicking noise in the dash even though no flashers are on and my trunk unlatches. I get out and close the trunk, but it unlatches again if I have the headlights on.

    Before I call the Ghost Hunters - does anyone have a reasonable explaination for this or how I might remedy this problem (Preferably without taking it to a dealer.)
