VW Jetta TDI



  • dragnbarondragnbaron Posts: 11
    Had a quick question...
    I just recently bought a 2006 TDI jetta. Ran beautifully, and loved it. at about 500 miles the clutch froze in gear and it took the might of hercules (that's me) to get it out of 5th, on rt 287 in New Jersey (that was fun...). Took it to the dealership and they replaced the clutch, saying the compression plate was not put on properly. Now, it has about 2700 miles on it, and in 3rd gear i get this odd whinning sound... It sounds like a jet engine powering up. As soon as i let off the pedal it stops. It only makes this sound in 3rd... since i haven't been using third much because of that sound every time i do use it it sounds even worse. What could the problem be, will it go away, and sould i be worried?
  • bpeeblesbpeebles Posts: 4,085
    I dont want to alarm you... but that whine you hear is indicative of transmission gears not meshing properly.

    It may be as simple as needing an adjustment to the shift linkages (cables) or somthing within the xmission itself.

    There is the possibility that this whining will not ever be of any real concequence.... or may be an indicator of worse problems later.

    In any case, you should be informing your dealership of this whining often and make CERTAIN that your complaints are logged every time you mention it. It would also help if their mechanic hears the sound and logs his findings too. This may give you some recourse if somthing fails later.

    It may not console you much... but VW manual xmissions are more often known to be VERY bulletproof and not ever have issues even after 200,000 miles of use.

    Hey, thanks for the info. Part of the reason i did get a vw manual was for the longevity and safty of the vehicle itself. I actually tried something yesterday and seemed to work well, but wanted to run it by you real quick, if you didn't mind. Shifting normally (pushing the shift knob all the way as far as it will go) without being forceful at all it makes the sound... i just tried to let it 'slip' into the gear (similar to a short shift) just pushing it and letting gravity do the rest of the work, and the sound stopped (still a slight bit, but that happens in every gear and happenened in all of the new 06's i drove, even automatic). Now, i didn't think much of the sound until it got fairly bad the other day.... could it have something to do with the heat? Keep in mind, during the hot days i don't tend to prime the engine for very long, and vw suggested to not prime it at all because of the 'new technology.'
    Secondly, would it be a good idea to try another dealership as well? Like i said before, this is the second clutch already and it the last dealership messed something up i wouldn't be too keen on seeing them again. just a thought and was wondering what others thought and wanted to thank everyone for even the smallest amount of info.

    Your description sounds even more as if the cable-shift linkage adjustments should be checked.

    Yeah, it seems like i need a new transmission. The gears aren't meshing correctly in gears 2-4. I'm taking it back to the dealership i boughjt it from and the one which installed the new clutch, hopefully nothing else will go wrong or i'll have to declare it a lemon, but it still wouldn't stop me from getting another tdi.

    is this the only 2006 vw jetta trim that uses diesel? isn't diesel a very bad pollutant in the environment?
  • dragnbarondragnbaron Posts: 11
    what do you mean by 'jetta trim'? On the contrary, diesel is actually less of a pollutant than regular automobiles. the downside to that low pollutant is slow speed, but much better gas mileage. One of the reasons that the emissions are darker is that in most diesels (and with the new law, in America, all the new diesels) pass the exhaust through the engine before releasing it into the air, that way it reduces some traces of sulfur as well as other pollutants. For any diesels prior to 2007 there are new emissions tests. In New Jersey, at least anything 2006 or lower does not have to have their emissions checked because it is significantly lower than normal gasoline engines.
    The U.S. just upped it's restrictions on diesel emissions because of the trucking industry. It's causing alot of pollution because there have been no emissions checking in most states, until now. Now, more than likely, pollution from trucks will go down because of there new laws, and new technology.
    Mercedes has a new exhaust system out, for their diesel car, that they fully explain in detail and show how it lowers pollutants. Basically, what i just said, it runs the exhaust back through the engine several times before it lets it exit the vehile, pretty neat.
  • bpeeblesbpeebles Posts: 4,085
    Where did you get your info about TDI engine being a "very bad pollutant in the environment" ?

    A TDI engine is such a LOW polluter that you can sit in a running TDI in a closed garage and will NOT suffer from CarbonMonoxide poisoning.

    Also, since Diesel engines use up to 30% less fuel... they also emit 30% less exhaust compared to gasser.
  • shopgirl5shopgirl5 Posts: 7
    the EPA; vw doesn't carry the TDI in CA b/c of the emission issue
  • tech_headtech_head Posts: 1
    Yes, the TDI diesel is both better and worse that equivalent gas engines. It's better in terms of greenhouse gasses and several volatile toxics, and it's worse on particulates and NOx. Where I drive , NOx and particulates are less of a problem, so the decrease in climate destabilizing gasses is worth it to me. (And the particulate issue will get even closer when biodiesel and GTL fuel combi's become practical.)

    The EPA (and Calif Air Res. Board) has to make rules that make some sort of sense over the entire areas they cover. And neither is currently worrying much about climate change.

    So diesels are worse locally (although not necessarily in ways that matter where you are) and better globally (there's a soot and short term warming issue that complicates this picture, but again I'm more worried about long-term (multi-year) warming and the soot issue with TDI's is pretty well addressed and will get better as fuel improves.

    Injection timing is critical. I agree that the auto transmission lowers the mileage considerably. I have an'83 Mercedes 300SD turbodiesel with 4 speed auto transmission and I cannot get more than 27-28 MPG no matter what. But the car is much larger and heavier than a Jetta.
  • shopgirl5shopgirl5 Posts: 7
    cool, i want one...oh wait, i live in CA :( what do you recommend for an environ-friendly, non-hybrid car?
  • gagricegagrice San DiegoPosts: 31,180
    Find a used VW TDI with 7500 miles or more and it is legal in CA. Try Oregon dealers.
  • billinncbillinnc Posts: 10
    I would like to get some reports of mileage rates on Jetta TDI models. I have a new 06 model with auto transmission and am getting 36 mpg, mostly city driving with air conditioning on. The car only as 1050 miles on it. I assume I can expect better mileage after it gets a few more miles on it. I hope so! I have heard that the best mileage comes after 5000 miles. Any comments would be appreciated.
  • sebring95sebring95 Posts: 3,238
    Most folks I know believe 40mpg to be a respectable average for the automatic. 36mpg in heavy city with A/C certainly shouldn't be far off the norm. It likely will get better as the miles pile on, but you're not doing too bad. I believe the newer DSG six-speed auto is supposed to do much better, but I'm assuming you have the regular automatic?IMHO, a hybrid is better for the folks that actually drive 100% in the city. That's where they really have an advantage (mainly due to idling losses). Most folks buying TDI's are road warriors and the open road is why the hybrids seem to be less efficient than the diesels. I usually run 75-85mph with my TDI, and would still average in the 45-50mph range with performance mods. On the rare trip with lots of city, my average usually dropped to the low 40's. That's a manual tranny.
  • billinncbillinnc Posts: 10
    Thanks! I have the new DSG six speed auto. It is really a smooth transmission. I hope to get better mileage as time goes on. I purchased the TDI for alot of open road driving but have not had any trips planned so far.

    I've never concidered a vw TDI until recently. Does it sound clunky like an old 1980's disel? Does it really take off due to the high torque numbers? I think that after say 0-30 it would get slower due to the 100hp. Are these somewhat true or am i blowin smoke?
  • autoboy16autoboy16 Posts: 992
    Sorry if i'm reposting this. I found this article on ULSD. For those Acronymicly :P challenged like me, it stands for

    Ultra Low Sulfer Diesel

    And basicly all it is is diesel with only 5% sulfer instead of the 95% we already have. This diesel should be allowed in allomost all states. New York is the newest state to have diesel fuel. :)

    You know, i was a little hesitent to buy a diesel because of those concerns too, but i live in New Jersey and i do alot of city driving, but also alot of highway so i wanted something more economic than a hybrid. I almost bought an old buick diesel with 100k miles on it but someone told me to try a new jetta.
    So, i went on a test drive and was wicked surprised. I also own a 2001 ford focus.... with that i get roughly 21 miles to gallon because i live in such a dense area. Getting onto the highway with my focus is eventful to say the least, but when i tried the 06 diesel jetta not only did it pick up as quickly as my focus, for the size and weight it moved faster than alot of my older cars. Granted, it's not a race car and trying to go from 60-80 mph quickly is difficult, especially in NJ and especially with a manual, but it's just as quick as my focus.
    There is a bit more noise than i am used to, but going from a loud mouthed lightweight car into something that weighed three times as much with less horsepower, speeding up gives me hardly any noise at all. i have been having some trouble with mine recently which has given me alot more noise, but that is something uncommon and should not be anticipated if looking into a new deisel.
    Even the Mercedes deisel is just as quick with much less sound than there used to be. One problem with the older diesels is that makes them a little louder is the engines are gasoline engines changed over to allow compression rather than combustion. It gave better fuel economy but had a REALLY loud sound.
    The one downside that i can see for someone in my position (inner city with occasional and frequent highway driving out of state) is the prep time in the winter. In older diesels you need to let the engine warm up before you drive it, the new jettas you don't HAVE to prime it, but i would recoment priming it for at least two minutes before starting it, int he winter, otherwise you get a unique 'clunk' sound.
    The thing i like the best is when i pull into a truck stop and have the truckers get out of their trucks to ask me about my car. That and the shocked looks on people's faces as i ask for a fill up of diesel. As sad as it is i still have to be VERY careful because many of the new gas stations around my area, the attendents don't speak english and try to fill it was regular instead of diesel, evn though it says in big bold letters DIESEL ONLY on the gas cap.
    In my diesel though, the best time for speeding up is between 2000 to 4000 rpm, which is optimal for the highway. Even with my city driving and the contrant stopping and going i still average a minimum of 35 mpg, and on trips to New Hampshire or Massachusetts i get a good 45-50 mpg at an average of 90 mph.... i mean 70 mph.... ;)
    The nice thing i like about these new jettas (as a side note) is the customability with the lack of aftermarked pieces. The lights at the feet of the driver and passanger can be changed for different colors, the chrome on the front can be changed to nearly any color with some metal tint, and the bottom of the jetta is ridged so rocks that pop up don't show scratches easily.
    I was surprised by the amount of things that came stock on the TDI. I have the basic of basic TDI's and i still have leatherette seats, traction control, in dash 6 cd, and 6 stock airbags. The next models add leather seats, sunroofs, satellite radio, two more airbags, and auto lights.
    All in all, i like my jetta, but i am having tons of problems with my clutch and transmission, and i'm not the only one who has had this problem... but i think that those problems will resolve in the next year if there are more cars with those problems. When the 08 models come out i'm sure all problems will be solved.
    If you're thinking about a diesel jetta i'd recomend test driving an automatic in sport mode, because there is barely any, if any, resistance in the new jetta manuals.
    Probably more info than you asked for, but thats what i think of them.

    Alot of the diesels in the late 70s and into the 1980s were converted gasoline engines. The demand was fueled (pun) by the oil embargo of 1974. The VW TDI is a different animal. They don't seem to slow down or loose power because of the superb mating of transmissions (ie gear ratios) and engines. Don't take my word for it. Go drive a TDI. You will be very surprised what 100ho can do. That's because the torque is more of an issue than HP! That's what I did and a month later I decided to buy one.
  • autoboy16autoboy16 Posts: 992
    Thanks for the edmunds Long Term Test on the jetta TDI :). I guess i can wait until ULSD to come out to try a TDI jetta. I'm guessing (hoping) dealers will have many more in stock by then. Trust me, i like vw's automatic better than their manuals... Not to mention i don't know how to drive a manual... yet :D. I still cant get over the fear of accidently putting regular gas into the tank instead of diesel... :sick:
  • bpeeblesbpeebles Posts: 4,085
    No need to wait for ULSD... it is becoming widely available as I write this.
  • autoboy16autoboy16 Posts: 992
    And unfortunatly the jetta TDI isn't for 2007. But the good news is that "i just saved a lot of money on my car insurance by selling my lambo, porsche and nsx" j/k (about the exotics)

    seriously, Vw heard me and is dropping the 1.9liter diesel for a bigger (and yes newer) 2.0 version. I found that here on :)
  • billinncbillinnc Posts: 10
    I also heard the TDI will not be produced in 2007 but will return in 2008 (with more emissions control). A larger engine would be nice but it probably will reduce the mileage rate. I doubt that VW will change the gearing in the DSG auto transmission since it is fairly new. I also heard the Pasaat will retun in 2008 with a diesel engine but larger, maybe around 3.0L.
  • autoboy16autoboy16 Posts: 992
    Thats unlikely. It could use the jettas diesel. It did in 2005 have the 1.9 TDI

    Volkswagen Cuts Price on '07 Jetta, Revises Diesel for Upcoming New Beetle from, inside line.
    Date posted: 06-28-2006

    AUBURN HILLS, Mich. — The 2007 Volkswagen Jetta, which goes on sale in the fall, will start at $17,120, including a $630 destination charge. The 2006 Jetta started at $18,530, including destination.

    "We lowered the price to be more competitive in the segment," VW spokesman Tom Wegehaupt told Inside Line. For 2007, the Jetta also gets an optional iPod adapter, simplified cruise control, an optional premium sound system and a standard tire-pressure monitoring system.

    The German automaker dropped the diesel Jetta and the 1.9 TDI diesel New Beetle for 2007. Wegehaupt said all-new common-rail diesel technology will be forthcoming on the New Beetle for calendar-year 2008. He said the new 2.0-liter diesel engine is estimated to deliver 140 horsepower and more than 200 pound-feet of torque while meeting tougher U.S. regulations. Volkswagen said a special model of the New Beetle is also planned for 2007. It will be a white-on-white model that will go on sale in spring 2007. It will feature a white interior and exterior and a white trunk lid, although the top will be black. No pricing has been set yet.

    What this means to you: The Jetta is now priced closer to its natural competitors, making it an easier pill to swallow for those looking for a solid German sedan for less than $20K.

    I live in Chicago (60630). Does anyone know of a shop that will work on and understand TDIs? I have no confidence in the dealership in the area.
  • I would like to know if the Fuel filter has to be flooded with fuel or will it self prime?


    04 jetta TDI Auto 20,000 miles
  • bpeeblesbpeebles Posts: 4,085
    It is a very good idea to prime fuel-filter after changing it.

    This is a simple matter of turning on the key (NOT starting engine) and allowing the fuel-pump in the tank to pump fuel into the filter. (you should be doing this to wait for the glowplug light to go out anyway)

    Just turn the key to "on" and you should hear the fuel pump 'hum' for a few seconds....then turn to "off" -- do this about 7-10 times before attempting to start the engine.
