VW Jetta TDI



  • howardg2howardg2 Posts: 1
    Thanks for the information. My Jetta TDI has just 40K, and they charged me 180.00 to fix the flap today, but I am concerned it will go bad again soon. They told me to call VW and I did. They said it is not under warranty, but would offer me dealer credit for my "loyalty". should just be covered.

    Well, my 2000 passat wagon has 160,000 miles on it.
    I love the car but they no longer make a v6 wagon. so I have been considering the new jetta wagon diesel (after I have totally worn out the passat of course). but my friend told me that the new jetta diesel has some huge fuel filter problem that ends up costing the owner $10,000 to repair and that VW blames the car owner for putting in the wrong fuel? Ever heard of this?
    I mean I know that as a VW owner you need to keep a honda in your back pocket for emergencies. But my problems with my passat have mainly been with incompetent or inexperienced mechanics that don't know how to work on these cars. But overall, routine maintenence is a must. so the new JEtta wagon TDI is problematic? My friend told me to get an acura wagon *yah, for $10,000 more dollars).

    Your friend has heard accurately.
    Many manufacturers have had HPFP issues with 2009 & later diesel cars.
    NHTSA is investigating VW for these issues in the 09 & later jetta TDI.

    Unfortunately the investigation has resulted in blaming mis-fueling.

    In response to ODI's information request for PE10-034, VW indicated that it had "found no defect related to motor vehicle safety with relation to the TDI Clean Diesel fuel system at issue in this investigation" and attributed problems with HPFP failure to operation with gasoline contaminated diesel fuel. Volkswagen stated that "even a small amount of gasoline in the diesel fuel may disrupt the necessary lubrication required and may cause the HPFP to fail." In response to concerns that fuel contamination was the major cause of HPFP and related fuel system failures, VW issued a Technical Service Bulletin in May 2010 (VW TB V011011 2023624 and Audi TB A011008 2023360-1), with instructions to inspect the diesel fuel for vehicles requiring fuel system service that have symptoms associated with HPFP failure.

    The bulletin states that "fuel system damage incurred by use of fuel not complying to ASTM-D-975 Grade 2 S15 (B5 or less biodiesel content) standards will not be covered under warranty." Volkswagen also provided information about 121 mis-fueling incidents reportedly acknowledged by consumers or dealers and test results for about 50 diesel fuel samples taken from complaint vehicles in late-August through early-October 2010. The mis-fueling incidents include about 20 reports involving incorrect fueling by dealer sales or service personnel and generally report symptoms such as rough running, stalling and/or no start within a few miles of refueling the vehicle with gasoline. Volkswagen indicated that the testing of fuel samples from complaint vehicles found that nearly 90 percent contained high amounts of gasoline. Volkswagen implemented design changes for the HPFP in May 2008, September 2009 and November 2010 to improve the robustness of the pump when used with poor quality fuel. ODI analysis of HPFP failures identified from all sources shows failure rates of 0.53% for MY 2009 vehicles and 0.11% for MY 2010 vehicles. This investigation has been upgraded to an Engineering Analysis to continue to investigate the issues with mis-fueling and HPFP design identified during the Preliminary Evaluation.

    I have had issues with my car almost stalling out when pulling away from a stop, but have not put anything other than diesel in the tank. I can't vouch for the quality of the fuel, but have certainly filled up at locations that had ULSD. I wonder what VW would say if I had the HPFP fail and found no gasoline in the tank.... I hope I don't find out.

    We VDubers are all in the same boat no matter if you have a new one or and old one.
    My BRM came with a list of inherent mechanical issues that will keep costing me 3 to 4 time any estimated savings on diesel fuel mpgs compared to reg unleaded.
    I have had VW's spread out over 50 years and other than a rare 72 super beatle they have all been problomatic.

    The new non hybrid 2011 cars rated at 34 to 40 mpg on reg gas that are the same size or larger than the Jetta TDI are, for my next vehicle the ones I'll be shopping for.

    VW reliability issues are part of the ownership experience as they jump from one half baked idea to another and use us owners as unpaid research and develpment guinea pigs..

    NO more VW's for me, I'm done. As they say, "I'm gettin' too old for this ####"

    I am sorry to hear your Sportswagen TDI has not worked out for you. I had high hopes for that car. Looking at the alternatives that are non hybrid, well there are none. The closest would be the Hyundai Elantra rated at 33 MPG. The average owner is claiming only 28 MPG combined. It looks like the problem in the USA is our substandard fuel. It is hard to say what damage our ethanol laced gas is doing to many vehicles. How much has it shortened the life of those cars. I am holding out for a diesel SUV. I would like a smaller size than the current half dozen diesel SUVs being sold.

    I really can't say I blame you there. All brands have a certain percentage of "Mr. Hyde" samples. They also have a pretty annoying smaller percentage of "and when its bad its REALLY bad" samples. VW for some reason seems to have a higher percentage of those Mr. Hyde samples (with sub categories) than (for example) most Japanese oems.

    But then on the other hand, they do succeed in having a good percentage of Dr. Jekyll samples also. I just ran a like for like cost comparison on a 03 TDI Jetta and 04 Civic. Let me be one to also say it is really an apples to oranges comparision. Since this is a Jetta TDI thread, the real competition is the Toyota Camry Hybrid. Be that as it may, the gasser 04 Civic costed a lot more than the VW Jetta TDI. In discussion round numbers, app $4,300 in 120,000 miles. Msg 2197

    "What would it take for YOU to buy a diesel car?"

    Let me say this as clear as possible while not shouting. I am/ was in no way unhappy with the 04 Civic. In fact, I am VERY happy with it and it fulfills the reasons I bought it, ...daily commuting. So by default, the VW (Jetta TDI) has been truly a "cut above".

    Does anyone know how to disable TPMS on an 09 TDI Sedan? Currently I will be running on my spare for a few days (tire with sensor is in shop) and I would like to disable the system so that the light will be out. Would it require a code change with VAG-COM?
  • eliaselias Posts: 1,900
    Some winters i use black electrical tape.
    imho the TPMS system is waaaay more trouble than it is worth.
    when the TPMS valve stems fail/leak, consider to replace with normal valvestems and start a 401K. :|

    I was talking to the guys at our local Goodyear about them, and feel that they are a pointless waste. I check my pressure at least 2 times a month since I drive about 1K a week and want to ensure they are good.

    They said that once the batteries go bad in the sensors, you need to replace the entire sensor, not just the battery inside. Not sure how expensive that will be, but it seems that you have to go to the dealership to have them reprogrammed.

    Currently I am driving on my spare (Bridgestone Turanza ER300) until I can get a new wheel. Does anyone have any experience as to how well this tire will hold up? I have about 1200+ miles to travel before I can get the wheel replaced.

    In the meantime, my TPMS light will be on as my current wheel is at the shop with the sensor still inside it. My light is now flashing or steady, with annoying messages telling me that my tire pressure is low.

    In hindsight, I should have asked them if they could mount the tire back on the damaged wheel, and throw it in the trunk so the car's TPMS will be happy :)

    The tape option sounds cost effective and functional, but I don't think it would pass inspection :P
  • I have a 2007 Jetta with the TPMS system. One sensor did fail, as the dash light came on, but all the tires were at the correct pressure. A trip to my Goodyear store and they found the bad sensor. They had to get a new sensor, which was about $100 repair job. Looks like down the road, these things will create a maintainence issue at $100 per wheel.

    I check tires about every 2-3 weeks, so normally not an issue, but recently was driving to get on the freeway and the light came on again. Stopped and checked pressure, and sure enough a back tire was low. Took a further look and had a nail in the tire.
  • shriftyshrifty Posts: 255
    One of my tires has been patched a few times now due to nails or staples (the big ones). Fortunately I didn't lose air from them, but noticed the bits of metal sticking out. I would rather check my tires weekly than pay a few hundred to have the sensors replaced. I'm not sure what the lifespan is on the TPMS sensors. More than likely I'll have the car programmed to ignore them once they go bad.

    Have a 2011 Jetta TDI Sportwagen, 6 speed manual. While teaching my son to drive the stick shift, with only 4,600 miles on it, it stalled and would not restart. Took a day to diagnose, but the throttle body had to be replaced. They said the plate was binding. Must have shut off air to the engine? Anyway anyone else have this or similar problem? I just got a friend to buy one before this happened!
  • I have a 2010 Jetta TDI with approximately 15,000 miles on it. I notice that sometimes it loses power momentarily at highway speeds, and at lower speeds as well, but not as often. It's usually when it is cruising around 1,800 RPMs, regardless of speed. Once when I was driving in stop-and-go city traffic, it stalled...right out of the blue. I was idling, and it just stopped running. It made me think that this might be what is happening at highway speeds as well, but since it has manual transmission, the momentum must be forcing it to restart itself. Nothing has shown up in dealer diagnostics but, then again, trying to explain something like this to an undedicated service advisor can be quite trying.
  • I've noticed the dual cooling fans working at various times in my 2010 Jetta TDI, even when it is stopped and shut-off after driving for a while. This is normal, but I've also noticed that sometimes the two fans kick in and operate at a much higher speed than I am used to witnessing. In fact, they start up sometimes when I'm in traffic, and they are going so fast, it sounds like a turbo-prop is coming in for a landing. I thought maybe it was something else, like the fuel pump, or worse, but I've manged to pull it over quickly enough to lift the hood and witness them still operating at this speed for a few moments before they slow down to a more normal speed. Are they two speed fans? Has anyone else experienced this?
  • bpeeblesbpeebles Posts: 4,085
    Yes - 2 speed fans.

    However, I would expect it to be VERY rare to have them both running at full-tilt. Mine have never-ever run like this.

    I could surmise a situation where they *might* both run at full-tilt (add all these together)
    *) VERY hot ambient temperatures
    *) Air-conditioning running at full-cooling
    *)stop-n-go traffic (not enough natural airflow thru radiator)

    With that said, unless your engine-temp guage starts to climb, there should be no harm to your engine. The cooling-system is doing its job.

    um--- a diesel engine DOES NOT HAVE A THROTTLE-BODY!!

    The only thing in the intake-tract is the anti-overrun safety valve. This is normally FULLY open while you are driving and snaps shut when you turn off the key.

    Its purpose is to save you (and your engine) from self-destructing. A diesel engine runs on oil --ANY oil-- including its own engine-oil. It is possible for an oil-leak into the intake (from the turbocharger) to make a diesel engine race at full throttle out of control. It would self-fuel itself until all the engine-oil is consumed. (or engine melts!!)

    Here are some Utube examples of what can happen when this safety-valve does not close when you turn off the key.

    You can imagine what happens when a diesel LOCOMOTIVE goes into runaway condition.
  • If your DPF is in a regen , both fans will run. This is to circulate air around the tight area of the DPF, so that no damage is done to surrounding equipment.
  • uvroweruvrower Posts: 10
    I hear you and do not dispute you. However VW called it a throttle body and it states so on the repair receipt. So it may be the overrun safety valve, but I will tell you the engine runs much better now than it has in 3000 miles. Revs more freely and more smoothly. Might have been a progressive failure
  • The so called 'throttle Body' is actually 4 butterfly valves that restrict the air on one of the intake valves on each cylinder at lower speeds to induce turbulence in the combustion chamber for a better burn.

    I wish these guys at the STEALERSHIP would explain this kind of stuff to CUSTOMERS. :mad:
