    Your car is still very new. Wait another couple of thousand miles and see if your MPG improves.

    What kind of driving do you do? City/Highway? When you fill up your car after going 257 miles, how many gallons does it take to fill up the tank?
  • I don't know about the new ones, but if you are having electrical problems now, then I think it may be a good idea to get out while you can.

    my 01 1.8t has had electrical issues since the day I bought it. In fact the north american vw plant has gotten various final warnings to fix their electrical issues or be shut down. My vehicle is currently in the shop, and has been for the past 2 wks, with more than $2000 in electrical problems, all of them recurring issues (been replaced once or twice before). It has had electrical problems since it was 40 days old. GET OUT while you can. Some vws run great, but it has been my experience (and many others) that the ones that have electrical issues will have them for the rest of their lives.
  • I have the same car, and had the exact same problem for more than a year and a half. After 2000 in false repairs, I let it go until it finally died on me. The problem was this, there were two different sensors out: the crank shaft sensor, which detects the position of the wheels while the vehicle is driving was shorted. Also, the air flow meter had a faulty sensor which caused the vehicle to alternately have to rich and too lean an oxygen supply to the fuel system. Eventually this led to needing a new fuel pump relay, and six months later a new fuel pump.

    Computer connector is under the steering wheel above your left ankle when you are sitting in the drivers seat. I have used my VagCom on so many VWs that I can plug into the connector in the dark without even looking.

    That is the first place he looked. Doesn't seem to be there. Should he look harder or would the 98 Jetta GL have it located someplace else? Thanks again.

    Back to Jetta brake problems. Does anyone else out there have spongy brakes on the Jetta with a slow fade to about an inch from the floor. When I'm at a three minute light I have to pump the brakes up. Had a VW tech drive and brake the car and he says this is normal and that it is a frequent complaint of Jetta owners. (It is on its forth maser cylinder.) Anyone else. Seems odd that you would have to loose control of the car in order to regain control. Thanks bpeebles. I don't think I'm crazy and I'm running out of options. He also told me that the booster cylinder has to be "matched" with the master cylinder. Anyone ever heard of that?

    My neighbour's daugther has a 05 Jetta 2.0 L auto with about 15,000 miles, he complaint that the brake is not grabbing that good, the dealership change the master cyclinder under warranty. So far my 04 GLI (with a bigger front disc rotor than yours) has no problem after 23,300 miles.
  • Find a new mechanic. This sounds like nonsense and is his wawy of saying "I don't know".

    If your pedal is sinking you have something wrong in the brake hydraulics. It's supposed to be a closed system under high pressure, so pressure is being lost somewhere. It's the mechanics job to find out where. I really doubt that thousands upon thousands of Jetta owners are pumping their brakes at stoplights as we speak. A clever mechanic could have isolated the master cylinder and tested it by now.
  • I just took my 05 Jetta in because it has been shutting off right away in the morning.. by the way, my car has 14,000 miles on it ..when i get it started the second time, it "chuggs" the first mile or so, when I am in first gear pulling into traffic, it doesn't want to go..it does this about 3 to 4 times a week..I took it to VW dealership since it is under warranty..they couldn't duplicate the problem and no codes came up..I took it back down a week later and left it there for a week until they noticed it did the same thing in the a.m. when starting..here is what they found:
    system was not holding fuel pressure so i got a new fuel pump. the air temp sensor shorted because the mass air flow sensor failed.got a new one of those.. coolant temp sensor shorted, so i needed a new one of those...My question is this..I have seen so many messages saying how vw is unhelpful and i have experienced it myself..when i got my car back, the very next day my car shut off again after starting it and now the epc light is on...they told me to bring it down..i did, and then i had to get a rental car.as i was at the rental car place, vw called me and said nevermind...we cannot fix it anymore, there is nothing else wrong with it...she said i could bring it back in one week, because that is when the head manager person will be there..she gave me some cockamamy reason about the cost of fuel on the east coast and since it was only happening in the morning, then oh well...(i had to put my flashers on to avoid being hit because i coudnt drive in first gear..it only chugged)..what am i supposed to do now? i can see this is a commom problem, to give people the run around..i am not going to put up with it..the car has 14,000 miles on it and should not have needed new anything!!it is highly inconvenient and annoying and new cars shouldn't do this..what do i tell them? what is really the problem? why don't they want to fix anything?? any help is greatly appreciated! :confuse:

    The OBD connection is located inside the small rectangular access panel right above the cigarette lighter. Just pop out that panel and you will see the connection (I have a 1997 Jetta)...

    HTH :shades:

  • The history: I bought a 2001 Jetta a year ago and now the Speedo/Odo has quit working. I brought it into Lithia and they told me I would need a new cluster. They said that would run me about $1200 (including labor, etc.). I could in no way afford that (All inclusive warranty doesn't cover the instrument cluster - First Extended Sevice Corp.). I figured I would try to find one on my own and replace it. There are a few on Ebay.

    Now the problems:

    1. I failed smog because the speedo doesnt work. So now I need to fix it right away in order to register the vehicle.
    2. The smog report says the speed sensor is shot.
    3. The Dealer (Lithia) says its the cluster.
    4. They also say I cant just use another cluster. It wont come on. They say that I will need a new ECM or find a cluster that matches my ECM. They also say that the Odometer will be permanently screwed up.

    Is it really that complicated to fix? There is no way I can come up with 1200 bucks by the end of the month when my registration expires. Lithia is pretty much the only game in town for VW's so I am afraid that they may have me over a barrel. I did not buy the Jetta from Lithia but the used dealer I bought it from only fixes what is covered on the warranty.

    Any information on what my options are would be greatly appreciated.

    Thank-you, EJM

    Lets just say we all hope your problem is the "speed sensor".

    The cluster is electronically "keyed" to the engine computer and your keyfobs (it is the cluster that "reads" the keyfob when you start engine.) Replacing the cluster may be a HUGE deal... or you may get lucky.

    Perhaps it is time to find somone with a VAGCOM and do some diagnostics.

    BTW: Why the heck do people purchase extended warantees if they dont cover the common failure problems? I have NEVER purchsed an extended warantee and instead put the $$ in the bank incase my car breaks. If it does not break... I get to KEEP the $$ towards the purchase of my next car....After doing this for about 20 years.... I will soon be able to pay CASH for my next vehicle if I want.
  • This was the first time I bought from a dealer. I understand things like the battery not being covered but never would have imagined this. I have never even heard of a cluster needing to be completely relaced and why it isnt a stand alone unit completely mystifies me. On the plus side, in the first year, the warranty did cover the water pump, thermostat and starter which have all been replaced. Although that does make me question whether I will ever own another VW. I bought it at 48K and am now at 51K miles so I'm not tearing the thing up.

    What do you mean by getting lucky? Do I have a chance in that or is it pretty slim odds (like finding another vehicle with the exact same programming.)? I ask only because I'm that desperate. I can't afford to be off the road and can probably get a 1 month fix-it permit but eventually will have to cough up the money if I can't find an alternate solution. I called the service center at Lithia and they suggested I sell it or trade it in. For a broken Speedo?!

    Well I've had a similar problem. I own a 2001 Jetta, and about a year ago I started having problems with the brakes, ever so often when I go to brake I either hear a sound like a spring popping or a faint grinding noise. I have to pump the brakes pretty hard in order for it to clear. I've taken it in to a mechanic and they coulnd't find anything wrong. And while getting other repairs done at a VW dealership I asked them to look at it and again was told they couldn't find anything. All I know is if I'm going about 5 MPH and trying to brake that's when it happens.

    Can anyone help me out with this. I have a 2001 Jetta that has started having problems with turn signals, when I go to turn them on, they work for a while and then start click irratically and sometimes they even just stop working. Then after a few seconds they start working. I've called a VW dealership and was told that I may have a faulty relay. Does anyone know where I can find the relay box?

    Just got my son this Jetta, only 50k miles, nice car. He put a cold air intake on it, ran great for about a week then started it the other day and the idle is just racing up and down, it runs good at 2000 to 3000rpm but as soon as you let the peddle go back to idle just has this loping from 700rpm to 1200rpm then it will shut off. We checked the intake line and is tight, no leaks. Any suggestions. :confuse:

    Possibly a bad O2 sensor? My little brothers car did that and he had to have the sensor replaced (his car was a Mazda 626 though).
  • The battery in my 2001 Volkswagen Jetta, 4 cylinder, 2.0L, died this week. I purchased a compatible battery from a local auto shop and replaced it. The car starts up fine and runs the same as it did before the battery died. However, a few other problems popped up. The radio now doesn’t work at all. The 2001 Jetta has a safeguard feature that requires the radio to be “unlocked” after the battery is replaced – but nothing shows up on the screen at all. I checked fuses (that I believe are) associated with the radio, but can’t find one that is blown. I took many fuses out and put them back in, with no avail.

    Also, the clock and the digital trip odometer do not stay set. For instance, I set the clock and when I turn off the car and then turn it on again, it returns to 12:00 and the trip meter is back to 0.0. If I turn the car off for just a few seconds and restart, the numbers stay. But if I wait more than 30 seconds and restart, all is lost.

    I thought that this could be an alternator problem. But I followed an alternator test (taking the negative electrode off the battery for more than a minute and the engine continued to run), and it worked fine.

    Ever heard of anything like this? Any suggestions for me to fix it myself? I’m at a loss…

    Thanks for any help you can provide!

    Hello! I just leased a 2006 Jetta 2.5. I'm averaging about 70% city and 30% highway miles and have only been able to get about 15.5mpg. Does that seem a bit low to anyone else? I've filled up about 6 or 7 times since the car left the lot. Any insight would be appreciated. Thank you in advance.
