    You'll need to post more info. What did it sound like? How long did it run? Did you check under the hood? What engine do you have? Thanks.

    Hi !

    My rear light started acting up (well it should be called 'acting down' as they were not operational from time to time). It seems that my light switch broke and after replacing it everything is back to normal.

  • Hi There,

    My husband just bought a 2002 VW Passat W8 in May of this year and a month later was experiencing deep puddles of water in the back driver's side seat. We lived in Seattle at the time, so it rained often. Shortly thereafter, he began haviing electrical issues with the car, such as the trunk not opening, and the automatic door locks not working.

    He bought an extended warranty from the dealership in Oregon where he bought it, and just brought it into a VW here in Minnesota for the 60K miles routine maintenance. He asked then to check out the electrical issue as well since it was already in the shop. The mechanics just told him that it would cost $4000 to repair the electricacl system since water had flooded and corroded the system. He said the the extended warranty would not cover this repair since it wasn't a common or acknowledged problem.

    Could you send the pdf for the recall again or a link so that we have proof that this is a common enough problem that a recall has taken place? I would really appreciate your assistance and would be forever grateful. This car really was my husband's dream car, and now he calls it "Christine" (from Stephen King's movie) because it's been nothing but trouble since he purchased it. Thanks so much.

    Krzyss,

    Do you mean the light switch on the dash or the switch on the brake pedal, under the dash? Just curious. My brake light switch went bad once, but it kept the brake lights on all the time, even when the car was off. I had to pull the fuse to stop it from killing the battery before I could get it fixed.
  • krzysskrzyss Posts: 843
    The switch along the knob in the dash.
    It started a few months ago with lights not turning off after turning the switch and burnt plastic smell.
    I ended up replacing (or rather paying mechanic to do this) the whole switch in the dash.

    VW issued recall to fix moonroof drainage piping. Somebody got bridght idea that leaving the pipe open will probably splatter too much so they made the ends much narrower so water would trickle drop by drop.
    Well this design is prone to clogging and when it clogs water gets into the car and expensive electronics is on the floor under the driver's and passenger's seats.
    For more water fun there are drains under the battery, which when blocked allow water to enter the passenger side through cabin air filter opening.

    I think you can try to call VW and ask them for recall notices to be sent to you.

    PS This is recall for plenum - battery/cabin filter

  • I have a "new" to me 95 Passat. Tonight the interior dome lights, the power locks, the sun roof won't work. The clock resets to 12:00 every time you start the car. Could not find any fuses that we bad. Help?
  • krzysskrzyss Posts: 843

    Have a 95 Passat VR6, Got from a guy who got from another guy that got it from the owner. Know nothing about the car. Battery goes dead after sitting for a week or two. Not tagged. Daughter getting ready to drive and want it reliable. Slow draw somewhere? Any ideas where to check first? Heard I can disconnect the ground to the battery and use a test light on each fuse? Also saw a TSB on the radio drawing too much. Solution for that? Thaanks , Jeff
  • I would start with the obvious. If the battery is over three years old it probably does not hold a charge that well anymore. If the battery is good try connecting an ammeter in series with the positive battery terminal with everything on the car turned off. It should read no more than 1 microamp and only because of the car's dashboard display. If the ammeter reads more than this then there is a draw somewhere. The next step is to try and isolate the source of the draw. How? With the ammeter still in place, pull the fuses one by one and reinstalling the fuse if it does not stop the draw. Once you locate the fuse that stops the draw, you have found the circuit where the draw is coming from. The next step now is to locate the component in that circuit that is causing it. If you cannot locate by visual inspection, do the same thing as you did with the fuses. Disconnect each component until you find the one that stops the draw.
  • My car shuts off at random. It could be stopped at a red light or at a stop sign or driving 30 mph. I have no idea what is going on. Now i don't want to sound stupid, but I'm a 22 year old girl who knows nothing about cars. So i cant really tell you much other then that it stops when it feels like it, and I have to restart it again. It has never stopped when i was going over like 45mph though if that helps. I hope you can help me before I go to a mechanic and they screw me over for all my money. WHATS WRONG?? HELP??

  • finvr6finvr6 Posts: 1

    I have a 2003 Passat W8. Today, I am experiencing electrical problems. My remote key does not open the doors or the trunk (the battery was just changed). My gas gauge does not register the amount of gas in the tank (Just filled it). On my dashboard, the top spot that shows radio/cd/tape deck info is now blank. As I was driving today the dashboard lit up and everything was reset (clock, trip odometer). I cannot adjust the mirrors and the controls on the steering wheel (radio and cruise control) do not work. I have a little over 117,000 miles on the vehicle.
    HELP!!!
  • altair4altair4 Posts: 1,469
    So all this went south immediately after the battery was changed? I mean, on the first start after the new battery was put in? Not days later?

    I tried replacing fuse 21 and that didnt fix the problem. I encountered another problem - when I started the car, the radio came on in "safe" mode and then got a reading of 1000. My book says to enter the code on my radio card - the radio card is blank - no numbers. Is there another code I can use to get my radio to work?
  • My son has a 1997 VW Passat. The battery was changed and a new interstate battery installed. We cannot get the battery to stop draining. Within a few hours the battery is dead. I have noticed a "pump" running just on the right hand side of the motor (looking at motor) at the top and just below a circular electrical connection about the size of a tennis ball. IF you unplug the 5 amp fuse located just in front of the windsheild washer reservoir, the "pump" shuts off. I can disconnect the battery and it cuts off and stays off. If you unplug and replace the 5 amp fuse the pump continues to run. How long is the pump supposed to run and would it hurt to unplug the 5 amp fuse to keep the battery from draining? Thanks

    When the battery dies or you disconnect the battery, the radio will go into safe mode. You have to remove the radio and get the serial number and call or go by a VW dealer to get the code to install to get it to work. Haven't found my electrical issue yet with the battery drain. I wouldn't disconnect the fuse. It obviously has a purpose. There must be something else wrong.
  • folbfolb Posts: 54
    Until you find the problem, I wouldn't unplug the fuse. It has a purpose. Remove the neg. battery cable each time you stop the car. Pain but works.
  • I have a 2003 VW Passat wagon. The battery keeps dying. I've noticed that the Odometer and clock stay on all the time. Key removed, car off. Any ideas?
  • folbfolb Posts: 54
    Not positive but I think they are LCD and use minimal power. Unless something is wrong with it.
  • folbfolb Posts: 54
    Did you every get an answer to the battery drain issue? Mine does too.
  • hey same problem do you no where or what to spray?
  • We have a 2004 Passat and the vanity lights as well as the lights for the heat controls in the center console aren't working. We can't find a guide to the fuse box so we're not sure if it is a fuse or something else? Any suggestions?
  • Passats are bad for this..and my mechanic said there is nothing you can do about it..sorry i wish there was
  • folbfolb Posts: 54
    I was reading some more on this. I "HEAR" that you have to use a VW battery, I've read there can be a draw from the radio if the testing tool used to test for....... can't remember....... and the test is not terminated first. The radio then has a higher draw. Also the terminal on the starter solenoid get loose and has to be tightened. try those things and try to get on Alldata website normally reserved for mechanics and dealers.
  • I just fixed this problem on my 1999 Passat, it was the key switch. About $60 at VW or $15 at NAPA parts.
  • altair4altair4 Posts: 1,469
    Did both problems start simultaneously?

    There are online directions for replacing the bulb behind the HVAC plate (assuming this is the manual control not the climatronic one). Google "HVAC light Passat" and you'll find those.

    Does your vehicle have the homelink system built into the visor? There is a relationship between that and having the vanity lights go out.

    Does the rest of your electronics work, like the cruise control?

    Post more info and let's see what we can figure out.
  • Thanks altair4! We'll check out your suggestion regarding replacing the bulb. We just recently got the car so it was already a problem we didn't discover when buying it. The dealer said they would fix it but I'd like to have an idea what it entails before bringing it. If it was a simple fix like a fuse or a bulb, we can just take care of it. We do have the homelink but haven't programmed it and so far, everything else is fine.
