    I posted a similar message the other day and no one has helped!
    I leased an 06 jetta, package 2, about the same time frame. I am getting around 257 miles a tank and its incrediblu frustrating!

    I guess your engine is 2.5L, the mpg is really depends on your driving style. If you always drive aggressively, you mpg will hurt. For your reference, my 2.8L Jetta with 23,500 miles driving usually very aggressive (80 % Highway (75-95 mph) will give me only 19.8 mpg

    I received a similar runaround with the dealer when i was having problems with my 2002 VW Jetta. They could never duplicate the problem until after my factory warranty ran out. Once they fix the vehicle, put it up for sale immediately or consult a lemon law lawyer and somehow coerce VW to buy it back. You will regret keeping the car.

    Does the CAI that your son added have an "oiled guaze" airfilter? If so, then the oil from the filter can be sucked into and on to the MAF (MassAirFlow) sensor causing it to self-destruct.

    One way to check for baf MAF is to disconnect the electrical connector from it and the go for a drive. If any improvement is noted, suspect bad MAF.

    There are several fuseboxes... did you check them all? It sounds as if the fuse that maintains "standby power" to the radio, clock and other items may be opened up.

    Also, it is not a good idea to remove battery connector while engine is running. With todays cars with onboard computers, it could cause SERIOUS damage.
  • I checked the fuse box by the driver side door. I can't find a fuse directly related to the radio and trip odometer, etc.

    Are there fuses in other locations besides that by the driver side door?

    (Jessy) Your question was answered indirectly by several people. Your engine is still new.... The MPG will climb as the engine "loosens up" over about 20,000 miles. Also- as mentiond before... careful engine break-in is ESSENTUAL if you want it to attain maxiumum efficency.

    Also, as mentioned several times - your DRIVING STYLE may be the biggest contributor to best MPG. Basically - An efficent driver does not have to use the brakes very often. All stops are known WELL in advance and the throttle should be released. Following-distances should be sufficent that the brakes are not neede if the person in front of you is an inefficent driver. (uses the brakes often)

    A good way to think of it is this.... the BRAKE pedal is a fuel waster. It is only there to remove unwanted forward motion. Thus... if the unwanted forward motion is not there (better throttle control), the MPGs will go up.
  • I have a 2002 Jetta GLS Sedan and never received an owners manual to trouble shoot the symbol. Is there a place I can find out online or can anyone help? The illuminated symbol is yellow and is located inside my speedometer circle to the right of 20mph. It may possibly be an engine although I am not sure as I would expect a "Check Engine" type of light to appear. The symbol is somewhat square with something that looks like a cap on the top and right side and a blade at best guess on the left side. Maybe engine? Fan or belts? Any help would be most appreciated until I can call the dealer in the morning. Also need to know if I can at least get to and from work this weekend. Ugh....Thanks in advance!! GLad I found this site!!!!!
  • Hi Jaimee,
    I just bought an '07 Jetta on the 19th and I've tested my MPG twice and it's exactly 26mpg both times. I do about 80% highway, 20% city though.
  • jessyjessy Posts: 4
    Ok, mine is getting about 16 mpg. I feel very angry I was not told about the crappy mileage. I am mostly a city driver but I cant start finding out of the way highways just to save the $40.00 a week!
  • jeffyscottjeffyscott Posts: 3,855
    What did you drive before and what mileage did you get?

    For cars of about this weight (3000 pounds+), with similar engines (eg. 4 cyl Accord, Camry, Fusion, etc.), CR typically measures about the mileage you are getting in their "city" test. Their city test is much tougher than the Government's. Perhaps your driving is just similar to that used in CR's test.

    To determine what is causing the CEL (Check Engine Light) you car needs to connected to a device that can "read" the codes out of the onboard computer.

    Here is the official OBDII (OnBoard Diagnostics- version 2) list of codes; http://www.obdii.com/codes.html

    Some of the auto-parts places will "read" the codes from your car for no charge.

    HOWEVER: The light you describe does not sound like the CEL... you may be able to determine what it is from reading the owners manual.

    I have had the same problem with my 2004 Jetta as well! The problem has existed since I purchased it--brand new. I've brought the car in numerous times, they've also never been able to "duplicate" the problem, yet, they've thrown parts at it. It is very frustrating and I feel like the dealership thinks that I am just making this up. I'd be interested in comparing notes with you and maybe getting up the gumption to get something done about our situations! Thanks!
  • jettamnjettamn Posts: 4
    I may have jumped the gun in responding to your posted issue. The "chugging" caught my eye, as that would be how I would describe how my car acts in the morning. Typically, I drive it down a one mile road, stop, turn right, accelerate, and as I'm accelerating the car chugs--clunks--drops--whatever you want to call it. It feels like the engine is going to fall out. Not normal! I haven't had issues with it not starting. I've been told that I need to use a higher grade of gas, that certain valves weren't tightened, this that and the other things have been replaced. Nothing that they have done has altered my daily "chug."

    Thanks for the info, it is an oil-less air filter. I will try the test on disconnecting the MAF. We did spray some carb cleaner thru the MAF last night and it helped some, Someone told me when we added the cold air intake that the computer needs adjusting since it is a turbo.

    I have an 06 Jetta (~ 1.5 months old) and have the "chugging" noise on cold start up too. Well, my chugging noise sounds like it is coming from the gas tank (after a couple of miles it goes away). Does your noise sound like gulping or sound like gas when filling up?

    I am planning on leaving my car over night at the dealer and suggest you try to do the same. The dealer I bought the car from provides free loaners :)
  • We have an 06 Jetta 2.5 and get 26 in town and 29 to 34 on the highway at 70+ and we live in the high country so are climbing mts. all the time..

    The mileage really depends on how hard you are on the throttle.. With you mileage that low I would think you are just a bit hard on yours.. Would bet its your foot thats the problem.. Grin..

    However like others said the mileage does pick up as you get more miles on the car.. Ours is getting better but our 2002 Jetta 2.0 wagon is up to 30 to 35 mpg on the highway and started out low too.. We have about 40,000 on it now..

  • That cold start noise that sounds like all the baffles in the exhaust are loose is a common thing on those engines.. If its super bad VW has an update for the computer that they can download.. There is a service update on it.. However it makes little difference.. It last about 30 to 40 sec. and gets longer as the weather gets colder..

    I think its one of the things you will have to learn to live with on these cars.. However to make you fell better about it.. I would drop by the dealer in the early morning and ask one of the salesmen to start up a couple of the new ones to hear how much like yours the sound is.. Odds are its much the same..

    check this out, My friend "gave" me his Volkwagen Jetta III GL as a gift. The only problem was that the transmission was bad in it. I thought Ok i'll just go to the junkyard and buy one, get it thrown in for a couple of hundred bucks and drive the sucker. It only had 110k on it, ran good for about a month, then go figure the transmission started acting funny. Now you can manually shift this "automatic" transmission into 1st second and third. The transmission doesn't have this whole "automatic" thing down anymore. When you put it in drive it stays in 3rd. I'm lost, anyone think maybe another transmission, or is it possibly some module of sorts....please help.

    I've got a 2006 Jetta GLI with nav and XM, with three XM related problems:

    1. XM is constantly "Updating Channel Listings" (>50% of time) so you have no idea what is playing nor can you change channels.
    2. Car sometimes forgets that it has XM, cant find XM, requiring restart of car to "remember" it.
    3. Field where title and artist are displayed is only ~3 inches wide, while screen is twice that width, but all the extra space is just wasted. So instead of getting Artist, Song Title, and Album Title information, all I get is part of the artist, and part of the song title.

    Anyone know of any other occurences of issues 1 or 2, or any solutions to #3?

    as usual, any helpful comments or hilariously sarcastic replies are appreciated.

    If you sprayed "carb cleaner" thru the MAF.... you may have affected the MAF in a negative way. As I said before, the MAF wants clean air and only clean air to pass over its delicate surface. Any foriegn substance (such as oil from ait-filter or carb cleaner) can really mess up the MAF.

    Here are some links to help you better understand the MAF, how it works and how to diagnose problems.

    My daughter bought an '03 GLI VR6. The engine idles smoothly, but as you apply throttle the engine wobbles/shakes quite noticeably as it passes thru around 1000 rpm, then smooths out again. Dealer svc characteristically says no condition!?! Any ideas what this may be due to? Thanks in advance.
  • bpeeblesbpeebles Posts: 4,085
    Suspect COP since they were known to be troublesome on VR6 engines. (COP = CoilOnPlug ignition coil)
  • My transmission is in limp mode. It won't ever go out of limp mode (stays in 3rd gear). I turn it off...turn it on. nothing.. Needless to say it just sits around now. The only weird this I see is that the indicator for the gears says that it is in all gears after about 30 seconds. The only thing I noticed out of the ordinary was that the engine coolant was extremely low. I've heard that this can cause limp mode, but no extreme change in the temperature ever occurred. I was wondering if I unplug the battery for 30 minutes, would it reset the computer? Possibly takeing it out of limp mode even if for just a couple of minutes. I would like to know if it's electrical or mechanical.
  • I own 2 2002 Jetta TDI wagons. On both cars the front fenders are rusting badly at the wheel well. The dealer (and VW Customer Service) tell me this is not warranty work, yet the body shop insists that it is "perforation" which is covered by the warranty. I am getting angry and wonder if anyone else has this problem and if they were able to get VW to honor their warranty? thanks
  • I have been experiencing the same problem the "chugging" and the dealership couldn't care less. I have an '03 1.8T. I have taken my car into my dealership about 5 times for the same problem and they have not been able to fix it. They basically tell me there is "no problem." Actually I just had my car towed this morning to the dealership for the same problem. On top of that my car died over the weekend. I just replaced the battery a month ago and my alternater is just fine but I have no power in the car.

    I am betting the computer in the car needs to be replaced or reprogrammed. My plan is to sell my car as soon as I get it back from the shop. My advice for you is the same! I will never ever buy another VW again. Because since I have had my car, after buying it brand new in 2003 my car has been in the shop almost 30 times and that is not an exageration. Good luck!
  • I am having the same problem....what was the solution? Thanks.
  • That sounds like an O2 sensor to me. I had exact same symptoms on a Grand Am and my current A4. The problem is that sometimes no codes are thrown and sometimes there are several things that have similar symptoms. Sometimes the failure of one thing can lead to the failure of something else.

    The biggest headache with newer cars is that EVERYTHING is electronic and/or computerized. The alternator on my A4 went out while driving to work the other day and everything shut down one by one. In the end, the engine was still running, but the car would not even move because the throttle is electronic. 10 or 15 years ago if your alternator went out, you could keep driving...even maybe a day or two before you realized there was a problem. Even then, you probably think it was the battery or a solenoid. Not anymore. Batteries are not powerful enough to power modern cars without the alternator.
  • I have a 2000 Jetta 1.8t. The first time it wouldn't start on me was a couple weeks ago. After a couple hours it started right up like nothing happened. I had never seen that light on the dash and found out that it was the immobilizer. I then found out that a new key is $165 but now I'm not so sure that will solve the problem.

    Since that first time it has happened a couple other times but only lasted a few minutes before I could start it again.

    I got this car as a theft recovery (only have 1 key). When it was stolen they took the air bags. Over the past year I have noticed 2 intermittent problems that indicate a short somewhere in the dash/steering column. First:, once in a blue moon I'll turn the lights on and all the dash/panel lights will be out except for the lowest setting on the gauges. Then it will go back to normal a couple days later. Second: (this happened for several months then went away) Whenever I got out of the car after driving, when I touched metal I got shocked, strong enough that it really hurt sometimes. Like a static shock from carpet but much stronger.

    I've talked to a couple service guys at VW and they're thinking it is the instrument cluster, where it supposedly all ties together, and estimating $700 to fix it. (ouch!) So I guess what I'd really like to know is if this sounds right. Someone else suggested the ignition "barrel" on the column where the sensor is. If it is the cluster what does it involve to replace it? I'm pretty good mechanically but never done much with inside electrical. I'm quite broke at the moment so any help is greatly appreciated.
  • I just bought a new 2006 Jetta TDI, and had only driven it for 3 weeks/550 miles, when it failed. All the dash warning lights came on and were beeping. It was towed back to the dealship, where it was diagnosed with a bad instrument cluster. It has now been in the shop for over two weeks. They have tried to install two new instrument clusters, but to no avail. Has anyone had a similar experience? Advice?
