    The good news is this is a very inexpensive item, as Passat parts go. Make sure you get the correct color coded unit. Good luck!

    and I cannot locate this thing. They say it is located at the rear of the engine so I am looking for it near the firewall.

    1.8T or V6? I can find better pics of the V6. In either case, I think it's pretty much in the same area - did you take off the top engine cover? Admittedly, I haven't looked for this under my own hood, but will if you still need help (I've got the 1.8T). Let me know.

    but I think the crucial part of engine cover removal I did not see.
    Wish me luck later today ;-)

    I think if I were going to do this, I'd buy the sensor, the o ring, and that little metal clip (I can just see that thing zinging off into the nether regions of the engine bay...).
  • I have the same problem with my 1997 VW Passat TDI Diesel. I was wondering if you have received any responses. I can be reached at hmmr8@yahoo.com for any information on the correction of my problem.

    Thank You v/r Mike McGlamery

  • I have a 99 Passat 1.8T. The drivers side tail light was out and I replaced the fuse. After the brake lights and third brake lights remained on and the fuse for the tailight (#23) blew out again. I just got this car and need some help!!I have heard of a brake light switch causing problems?
  • The brake light switch is part of an integrated system which includes the ABS and the cruise control.

    Replace the brake light switch. The same thing happened to my wife's 2003 Passat. After the switch was replaced, that resolved the issue.
  • My daughter is away at school and the dealer can't get her in for 2 weeks. Her issue is the electrical items seem to work randomly as she is driving down the road. The horn honks, the lights will go on, the doors will lock and unlock, the alarm will go off. The turn indicators are not working either. All this started yesterday and seems to be progressing. Any ideas would be greatly appreciated.

    My first guess would be a wet (or failing) CCM (comfort control module) under the front carpeting (can't remember if under left or right side carpeting at the moment). Water can enter the car if certain drains clog (often the drains under the battery and brake booster, under the hood, near the back, under that black removeable cover are the culprit, but could be the sunroof drains). A wet CCM can cause bizarre electrical issues.

    Second guess would be a failing ground connection.

    Our 2003 wagon often will not start if the temperature is below 32. The engine will not
    turn over. The starter does not even engage. The battery has been replaced. This has
    happened at least 10 times causing us to be late for work and school on cold mornings.
    The car is sitting in a dealers service lot now. They cannot duplicate the event and say
    they cannot help us. Roadside assistance towed the car 68mi to the dealer. We are being asked to come get the car with no fix to the problem and are being asked to pay fora 400.00 40,000 mi service. All power seems fine inside the car when this happens. It seems that the starter is not being activated at all. Later when the temperature warms overfreezing the car starts fine. Sometimes the turn signal flasher relay will make random clicking noises for no reason or continue to click after the signal lever is returned to thecenter position after a turn. I hate to trade this car because Volkwagen can't diagnosean in warranty issue. Any ideas? Thanks
  • I just had the same problem with my 2006 Passat and they could not duplicate the problem either. VW Tech assistance told them to apply Stabilant to the ignition switches because the cold weather causes the switches to contract thus not allowing them to be contacted during ignition. The Stabiliant is supposed to allow contact to occur and ignition to happen even when the ignition switch has contracted due to cold. Good luck, not sure if it works on mine or not because unfortunately it is warmer now. I am close to trading it in because I want confidence in a car starting or at least the ability for a correct diagnosis.
  • Hi 95Passat:
    First of all, I wanted to thank you your TIME. I appreciate that you are taking the time to answer and in what way! :) I laughed a lot and it gave me strenght!!! Thanks again.

    So, here's the update:

    1)Went and bought couple of extra fuses. Switched them while crossing my fingers and no luck. :(
    2)Removed successfully the frame! :shades:
    3)Couldn't remove the radio... :( Tried with plyers, presure, everything and it WONT even move. It's very well installed...

    The radio is a Pioner DEH-1300. I don't think it came with the car because I got the manual from the Pioneer Web-site and it doesn't says nothing about a code, thing that I think it's present in the original stereos, am I right? Also, in the manual, it says that to remove the unit I need to use these special keys.

    At my local auto car shop I bought alltogheter with the new fuses the book for my car, and in there too they show you the "keys" to remove the original stereo. Actually, they give you the actual size just in case you are handy cutting metal. I don't know if they are the same.
    I also asked if they sell this: NO. Only for FORD.s>:(

    I asked at a guy in the shop, he owns a repair shop and he said to me that to remove the stereo would take about 45 min. which I know is not true, well, I hope so. Since apparentely, stereos can be put from the front or from the back and be tightly screwed in the case. I guess that if mine was place from the back, this isgetting seriously interesting... I got the book, I can remove the whole thing dash board apart if I want to now!!! :shades:

    I really want to remove the stereo. I guess I'll have to buy these keys somewhere. After all the time pulling and cur&ing, now has become PERSONAL!

    PS: Good job whit the regulator!!!
  • To all of you that said that my ccm or a bad ground thanks for the help the real problem was with the fuel module under
    the spare tire cuasing all these problems, always check your bus line, thanks : :shades:
  • :confuse: hi there i was wondering if there's anyone who can give us info on our problem. we noticed out headlights we;re out the other night and bought new ones. my husband replaced it and still not working. he also checked the fuses and said its good. does anyone have an idea on what our problem might be?

    thanks,
    gina

    I am having a similar experience with my 2003 Passat (85k). Typically the car lives in a warm garage but when it "sleeps" outside, it's 2 for 2 on the no start the next morning. After the first no-start, I replace the battery. After the second no-start, I went to Google. Any updates ?
    Thanks.
  • Does anyone have the breakdown of the fuse map? The manual is not helpful in that the symbols used on the card chart (taken from the car) have no explanation. Seems silly that I don't know what all these little symbols mean... or does it?

    I am at 70,000 miles and have just experienced a run of problems with my wagen. I have intermittent loss of power... when I push the accelerator to the floor, sometimes the car goes nowhere - but the RPMs rev, and sometimes it goes nowhere without revving at all. Multiple trips to the mechanic has done nothing.

    We've flushed the transmission, the water pump (which was leaking) has been replaced, and the timing belt (since they were in moving things around) has been replaced now.

    Thoughts? :mad:
  • a few things on this car that i just bought very cheap. first the abs light is on and the brake lite is blinking next to it!? i hooked two different scanners to the car to check the code and on both scanners it said error unable to read? also today i fixed two windows that where off track . after i finished i hear a clicking by the fuses and a light that is flashing by the driver side lock and a noise thats seems to be coming from the trunk lock?also i have no blinkers ive checked all the fuses are good! any help would be greatly appc.! thanks chace

    HI ALL, I HAVE A 02 PASSAT AND JUST GOT THE SAME PROBLEMS AS MEMBER PASSAT02. keys not communicating with comfort control module.car won't start with master keys or valet key. Door locks, windows, interior lights and trunk release DONT WORK. Battery is connected and powered; stereo, a/c, exterior lights, wipers all work. Fuses appear ok; pulled and reinserted each. Lifted carpet and found no visible evidence of water damage or residue in or around the CCM.


    I WOULD LIKE TO KNOW IF IS MY CCM FOR SURE AND HOW MUCH HAVE ANY OF U GUYS PAID JUST FOR THE CCM NOT THE LABOR. ANY HELP WOULD BE NICE THANKS.

    check your fuel pump module which is located under the spare tire,water damage to this module will cuase no start
    and electric problems.if it is your ccm i have a brand new one for a 2003 passat new in the box.
  • lazbusalazbusa Posts: 2
    how much do u want for the ccm and what r the number on top of it
  • nojunk, I have the same problem with my 2003 Passat. Just yesterday I noticed a loss of power when accelerating, also I noticed that my brake lights do not work. I'm thinking that both my be linked. Does anyone know about these occurances? I have 58,000 miles on my 2003.
  • hello Jhuettman, have you found any solution to your problems with the lights, fan and wipers??
  • vyskvysk Posts: 1
    I too have a 2003 Passat 1.8T that recently developed a loss of power when accelerating. I was also informed today that all my brake lights are also out. Related? Fuses look good. Before I take it to be serviced, were you able to ascertain the root cause of your similar problems?
  • I’ve searched the Passat forum and did not see a problem like this, so here it goes.

    Vehicle Info:
    2002 Passat, W8, 4Motion, ~70K miles, Purchased “new” “demo” (which means – the dealer’s wife and kids beat the snot out of it for a few months) from a VW dealer in ’04 with

    Problem:
    The cruise control will drop out as though the brake has been used or the Cancel button pressed. Resume always returns to the set speed. Once this problem starts, it will recur every 1.5 to 2 minutes. This problem has been present for as long as I have owned the car.

    When:
    On most, but not all, trips of over 2 hours.
    The problem appears to be temperature related.
    The higher the temperature, the sooner and more likely the problem will occur.
    On a day in the 90s the cycling begins within 10 minutes of setting the cruise. The certainty of occurrence is 100% when temps are this high.
    On cooler days – 20 to 40 – the cycling may not start until an hour or two has passed. But once it starts, it doesn’t stop until the engine is turned off and the car has a chance to cool down. For instance, on a ~7 hour trip I took a while back from Indiana to Toronto – temps in the 40s – the problem did not occur on the trip to Toronto, but on the return trip at about 3.5 hours the cruise started to cycle. I logged 43 cycles at an average interval of 1 minute 40 seconds until I stopped for dinner. The car sat for 35 minutes in 30 something weather. The cruise was fine for about an hour and 20 minutes then the cycling started over again.
    Terrain and precipitation do not seem to make a difference – up hill, down hill, rain, snow – do not make the problem more or less likely. Temperature is the only variable I can detect.
    A day of short city driving trips – no cruise – increases the likelihood. Even more likely if the temps are high and the car has been sitting in the sun most of the day. Certainty = 100%

    Home Made Remedies:
    Turning the cruise off with the slide switch and then back on makes no difference. Various intervals of on/off were tested.
    Pounding on the steering wheel and cursing in a loud and threatening voice has no effect.
    Turning other electrical equipment on/off has no effect.
    Muttered obscenities also do not work.
    A quick - stop the car, turn it off, sit for 30 seconds and then restart has no effect.

    VW Dealer Remedies:
    First, let me say that the dealer has more than fair. The cost has been less than $50 for multiple days over a number of years for a loaner car, testing and head scratching.
    The brake light switch has been replaced more than once… at least three times that I can remember.
    The throttle housing was replaced.
    All connectors that might have any bearing have been checked. Don’t know exactly what they are though.
    No relevant stored codes have been found.

    This problem is very nearly forcing me to trade this beloved car in for something else.

    Anyone have any insightful revelations?

    Thanks for your help!

    The cruise control on my '99 Passat V6 worked when the car was new. Another driver in the family used it for several years but never used cruise control. I've just started driving the car and found the cruise control doesn't work. When I tried to install a new 5 amp fuse in position no. 11, I found not only that there was no fuse there but also no contacts in the fuse box in that position! I assume that the fuse must be somewhere else, unknown to both the owner's manual and to me. (This is also true of the heated outside mirrors fuse). Can anyone provide advice? Thanks!
  • altair4altair4 Posts: 1,469
    No clue on the fuse position on the cruise control for your car. But if your heated mirrors don't work, it's possible the actual heating circuit on the mirrors are burned out. There is no timer on the heated mirrors. People have been known to turn on the mirrors and forget about them - for weeks, months, etc. The cure is to replace the mirror glass.
  • My wife drives a 2000 passat wagon that's had wacky electrical problems since birth...most common are warning messages for no (apparent) reason -- check engine, brakes, oil, etc...

    This morning the car wouldn't start...got it going with a jump and drove it a while to recharge, but when I turned it off, the radio stayed on, as did a fan under the hood and probably other stuff I didn't notice ... I assume this is what caused the battery to die in the first place... I've disconnected it for now but can't keep doing that forever ...

    I see so many Passat electrical problems posted here that I'm figuring someone out there can enlighten me ... I'm guessing alternator, but don't know much about cars... Can anybody clue me in? Thanks...
