Volkswagen Jetta Maintenance and Repair

  • Greetings all. Don't forget to turn the clock ahead Saturday night before you go to sleep. I own a 1992 Jetta GL - manual 5-speed - air condition - gasoline engine - 4-cylinder - 195,000 + miles on it. Recently, I disconnected the Oxygen Sensor since it was kaput and needed to be replaced but I had to wait a couple of weeks before I could spend the $185 to have it replaced. So I drive around for a week or two with a disconnected OS - bad gas mileage, of course. Then I had it replaced, everything OK now, right? Now, when I first run the car after it's been sitting for a while, or if I turn the car to the right, occasionally, I hear what sounds to me like the muffler making a clearly discernable roaring noise. No, not ear splitting, but you can hear it. After I've torqued the engine a bit beetween gears, the noisy muffler goes away. Sometimes, even when the engine's hot, I may yet still hear that noisy muffler sound again. But soon after, the sound goes away - just like that. This is not an easily repeatable noise, making it difficut for a busy mechanic to troubleshoot. Is this a case of a loose heat shield or maybe a a loose pipe...........or something else altogether? Or maybe the manifold exhaust clips up front in the engine compartment? The car seems to run fine - good gas mileage, shifts fine, etc. The entire muffler system, by the way, was replaced last year, including the catalytic converter. My VW mechnaic told me the muffler system looks good to him. Thanks. Edwardo

    i just traded a '79 gmc jimmy for a '96 Jetta Trek edition and found out it needed a new transmission. anyone know of a cheap repair for -$3600.00? (quoted price at several places) Would it be worth doing? :sick: (in Los Angeles)
  • I own a 1992 Jetta GL - 5-speed. I have noticed that, when I am in 2nd gear and I am moving at below 12 mph, the engine will begin to jerk, especially noticeable when I go over a bump. As soon as I feel that jerking motion, I let off the accelerator and the engine smooths out. As soon I am moving at faster speeds, the jerking motion vanishes completely. So it appears that, at speeds below 12 mph, I must remain in first gear but I must be careful not to torque the engine too high when it's cold. That's easily done, of course.

    It is never good to "torque the engine" when it is cold. Remember that over 60% of all engine wear occours when it is below operating temparture. (It has been shown that engines which are always runnning at temp. last much longer than those which are started cold several times a day.)

    With that said, You seem to be describing the symptoms of a cylinder not firing. (running on 3 cylinders) I would first suspect leaky sparkplug wires to cause what you are describing. If new sparkplug wires do not help, try new sparkplugs.

    After that, the order of items I would check are;
    1)ignitor coil
    2)Fuel filter
    3)fuel injectors

    I am deciding wether i should buy a 2000 jetta glx with 70k or not. I heard they have reliability issues but then again some people really like them. I am a college student and dont have alot of money for repairs, so if this is a car that is very unreliable please tell me thanxs.
  • hi,
    the locks are not working properly, excuse me, they are indeed working properly, just not from the drivers side door/keyhole.
    the key goes in, turns properly, its just the locks dont move up or down, nothing happens when i turn the key.
    i can open it from the passenger side, but not the drivers side.
    is the the key sensor probably?
    can anyone tell me exactly where the sensor is, and where is the best [low price] to purchase these replacement parts?
    thanks

  • You had a problem with jerking when you accelerate? I also have a 2004 Jetta that does this and my warranty is almost up, but my dealership is never any help. You said "they replaced it with a new one" What was replaced?
  • I just had that happen to me. I started my car and im not sure if I was still in park or in reverse, but I was reading something and all of sudden I heard a knocking noise. It came from the rear of the car on the passenger side. I have no idea what it was, but it was just a single knock and it happened about 6 times in a couple minutes and then stopped. It scared me because my warranty is almost up and I have been having other problems that the dealership cant seem to do anything about. I've asked around and no one has heard of this before.
  • I have a 2004 Jetta its a 2.0L, and its time for my 40,000 mile service. The dealership will cost me $500. I dont have a lot of knowledge about cars and I wanted to know what can I do myself that isnt too hard. Is it very much work to replace the spark plugs?

    I have a 2003 Jetta (70,000 miles) and it's has been running without any problems until recently. I have been noticing that the car would "jerk" when I am accelerating from a stopped position. When it first happened, it felt like something had hit my car from behind. Just like yours, it is also very inconsistent. When it happens, it only happens three or four times while driving on city streets, just after starting up the car. Then it seems to disappear. I have also noticed that it happens less frequently when the weather is cold. I called the dealership and they said that they can try to diagnose the problem by having a technician test drive it--but again, it doesn't happen all the time. I am bringing it in this week to let them look at it. I will let you know what they tell me.

    P.S. My car was fine until the manufacturer's warranty expired at 50,000 miles.

    hi phamo,
    i have the exact same problem. i have a VW JEtta 2000 1.8 T
    the car jerks forward sometimes while driving, a lot when its cold outside.
    have you managed to discover what the problem is ? do i need to replace the transmission. please any help would be useful. thanks afshad@nsm.uh.edu
  • afshadafshad Posts: 2
    has anyone found the solution or the cause of this problem. my vw 2000 jetta is having the same for a long time. rats at the dealership are ignorant as usual.

    I dropped my car off at the dealership and like tgirl1447 said, they didn't find anything wrong with the transmission. They said that they did a diagnostics on the "rough shifting" and everything was working properly. They also said that it didn't act up on them when they test drove it. So I still had to pay for the diagnostics--even though nothing was fixed. However, they didn't charge me for the recall--they had to add something to the back door locks. So look into that if you haven't already.

    Today's cars don't need much maintenance at 40K miles. Changing the plugs is an easy job on the 2.0L engine. Most VW dealers I've visited have their own EXTENDED maintenance schedule, but the manufacturer suggests much less. Change the plugs, change the oil, and go on your way.
  • bpeeblesbpeebles Posts: 4,083
    Have you ever tried to change the sparkplugs on the 2.0L engine? The center 2 (Cyl2 and Cyl3) are almost impossible to get a wrench on without REMOVING the entire intake manifold.

    If you know of a "trick" that would help the rest of us with this task that would make it an "easy job"... please enlighten us.

    I too am having this problem with my 2004 Jetta. It "jolts" forward and also feels like it slips gears when accellerating and scares the daylights out of me. The car had been PERFECT until new year's eve when I had a near-death experience.

    Driving to Philadelphia on 95, we merged into the flow of traffic. Once in the left lane and doing about 70MPH, the car made a loud CLUNK noise, my RPM's went way up, and the car essentially shut off in the left lane. Thankfully my hazards still worked - but the power steering was gone and it took all my strength to wrench the car over to the shoulder before almost being pummelled by an 18 wheeler behind me.

    I had it towed to the dealership and they said it was a blown starter coil. I spoke to the technician myself and he said that he'd never seen anything like it. It literally exploded and melted over itself. He said he's seen the coils go before, but NEVER on a car as new as mine was w/ such low mileage (25,000 or so at the time). Red flag? Maybe.

    After that repair is when the transmission jolting started. I work in a small town so my commute to work keeps my rpm's between 2K and 3K, and that's where all the slipping and jolting goes on. It's terrifying, especially when trying to merge onto the highway. It doesn't accellerate fast enough, and when it gets up there, it feels like it slips a gear. Took it back to the dealership and they found "nothing wrong with the car." They suggested that it was the way I was driving that was causing the problem. Um, I'm sorry, I didn't know that driving the 25MPH speed limit of the town I work in was going to damage my car. I even took a ride w/ the technician and it didn't do what I was describing. I thought maybe I was just paranoid after the new year's incident.

    Well, it's April now, and the car has about 40,000 miles on it, and the transmission is still doing this jolting and slipping. I was floored to find that this is going on with so many people's Jettas and was angered that all the responses from the dealers are all the same: "cannot replicate the problem." Has anyone had ANY kind of luck or made any sort of headway with this?

    My dealership has had my car all weekend. The rep just called and told me they drove it 53 miles and never had ONE problem. I have it DAILY and they had it for three days w/ nothing? Is this some kind of coverup?

    If anyone has had a similar experience, PLEASE, email me. At this point after reading all these sob stories I am considering unloading the car and getting myself a Honda. I can't afford to lose this much money on a car but I also don't want to die in a horrific accident. Advice appreciated!!!

    I got 2005 new jetta last year. Have several problems with it. When I drive above 65 mph or if there is some strong wind pass by, I can hear it like there's kinda leak with the rubber. I checked it over and over by my self, I couldn't figure out where the leak is(are). Next problem is the noise. After I start the car for several seconds and run it, I can hear this quick repetition noise (it's like when you tap all four fingers on the table or desk repeatedly) for several seconds which will stop after 10-25 seconds. I will bring it to the dealer where I purchase the vehicle for sure, but mean while, does anyone have the same problem with me? or does anyone know what's happening?
    Other thing is, I will have my car's interior detailed, mostly the ceiling part because it's full of dust/oil prints from the mechanics who installed the glass. Will this cause it to be saggy after a while? if it does, is there any replacement for it?
    So sorry it's long and thank you all in advanced.
    Any comments will be appreciated

    When I first bought my car (2005 jetta), I thought I'm gonna get a very comfy and safe car. Of course it comes with good power. I can speed up very fast. The interior also neat and tidy. But it has soo many problems with it, that I was thinking of getting Japanese car next time too. eventhough, mine is not as crazy as yours.
    I would suggest you to get a Japanese car instead. It will cost you more as you need to sell this one and purchase a new car, but it's worth your life.
    It's too bad that I am financing this car now, but once I paid it off, I will for sure switch back to Honda or Toyota. I had a Honda before, and it never gave me any problems. Very easy to maintenance.
  • gilletegillete Posts: 7
    If you don't a lot of many to fix this and that, I would suggest you to get a 2000 civic instead. You will safe a lot of money with it. It doesn't have a lot of power as Jetta does, but for sure, you will safe a lot of money

    Why pay to have the interior detailed? If dealership personnel caused the problem takeit back to the dealer & have THEM correct the problem - at no charge to you!
