    How's the reliability on the newer TDIs?

    Well, 2 of my dad's employees have/had recent jetta TDI sportwagons. 1 got rid of his after 2 failed pumps. The other still has his, but the engine is toast thanks to a failed pump that shredded and shot into the engine ... VW still refuses to fix it. He's persuing legal representation now.

    While the engine may not run, it is extremely unlikely (as in less than a one percent chance) there is any physical damage to the engine itself; the fuel system is another matter entirely.

    FWIW, the Common Rail HPFP issue is relatively well known in the TDI world; the jury is still out as to whether "mis-fueling" (i.e. putting either gasoline or contaminated diesel in the tank), low-lubricity diesel, or a poor pump design (by Bosch) is at the root of the problem.

    While I have no problem with VW quality per-se, I'm staying on the sidelines until this one gets figured out. Who knows, the new Mazda SkyActiv-D may hit the streets in the Mazda3 before VW has a fix for the HPFP.

    I may be speaking out of turn, and I just sent an email asking specifics again ... but why do you think damage to the engine is so far out of the realm of possibility? There are many documented cases of this same thing happening on the 2.0T engines. The HPFP follower wears away, the pump actuator arm the eats away at the camshaft, which shreds the rest of the head's internals and sometimes worse.

    Ok. Just heard back, and you are correct. Here is what the owner said:

    The hp fuel pump self-destructed and contaminated the entire fuel system.

    He definitely never put gas in the car. He is a truck driver, so, as far as I'm concerned, that's someone who is more likely to fill up a gas car with diesel out of habit, not the other way around.

    VW is denying the warranty claiming insufficient lubrication. The aren't claiming he put gasoline in because they have found no evidence to support that. Just insufficient lubrication.

    Anyway, the stories from these 2 owners are enough to keep me away from VW's TDI ... and that's such a shame. oh well.

    Just to clarify, as far as I know the HPFP issue with the early 2.0T engine (like from 2006(ish) and definitely not the new EA-888 motor which debuted as a 2008.5 mid-year upgrade for CARB states and in all 2009 and later turbo gasser models) has long since been fixed.

    As I understand the Common Rail TDI failure, the HPFP is located in the fuel tank and when it goes, the entire fuel system can be (but isn't always) compromised. The engine is not impacted in any way-shape-or-form.

    FWIW, the rumor over on the TDI Forum is that VW and Bosch have gone through a number of redesigns and the issue seems to be slowly getting better (i.e. cars with late model fuel pumps seem to fail with less frequency than the ones with earlier designs), unfortunately failures are still happening.

    For my part, as much as I'd love to have a fully tarted up 6-Speed (the kind with three pedals under the dash) Golf TDI, there are two things I'm less than sanguine about:

    1) The HPFP issue which I do believe will get corrected sooner or later.

    2) The inclusion of a Diesel Particulate Filter (DPF) as part of the exhaust system.

    The new Mazda SkyActiv-D engine will most likely have some of its own teething issues, and may also have HPFP issues (VW isn't the only company that's suffered with HPFP implementations in recent years). That said, by virtue of the lower compression ratio of the SkyActiv-D engine (14.0:1), Mazda is able to build the engine with no DPF or Urea catalyst and still pass all present and codified future emissions standards.

    My dilemma is that I prefer the way the Golf looks, feels and drives over the second generation Mazda3, however, Mazda seems (at the moment) to be on the best path to a clean, reliable and highly efficient diesel engine, and that may win the day for me in spite of how the Mazda3 looks.

    That's a bigger concern than even the issues themselves - VW service. I could always buy an extended warranty, but you still gotta go to that same dealer to get whatever it is fixed.

    The other thing is you used to put up with that risk to get a nicer vehicle overall, and with the cost cutting even that is gone. I'd buy a Golf or the old Jetta Sportwagen before I'd get a new Jetta sedan.

    Any how, just expressing frustration that the only two truly affordable diesels are VWs. We need more choices...

    Correct. As far as I know, that is exclusively an FSI problem, not TSI. FYI, VW extended the warranty on FSI engines for the HPFP and any consequences of its failure. I can't remember what the letter said exactly, but I believe it was 10yr/100k ... maybe even more. Personally, I'm just keeping an eye on the follower and have replaced it once already just as a precaution.

    Same here ... but not until its fixed.

    Sales of the popular Audi Q7 full-size luxury sport-utility vehicle increased 31% YOY to 790 vehicles sold, when compared to July 2010. The Audi Q7 TDI clean diesel model accounted for 36% of the sales mix in the lineup. Demand remained strong for the fuel efficient Audi A3, with 436 vehicles sold in July 2011. As consumers continued to show preferences for efficiency, the Audi A3 TDI clean diesel model accounted for 54% of the total A3 sales mix for the month.

    That is getting toward EU percentages for diesel sales. Audi has several great diesels in their lineup sold in the EU. I am waiting for them to show up here. Still dreaming of the A4 Allroad Quattro TDI with the same 2.0L engine used across the lineup. Rated in the UK at 51.2 MPG on the highway. I can live with that kind of mileage.
  • gagricegagrice Member Posts: 31,450
    Sales of Mercedes-Benz diesel models were up 134.1% for the month (913 versus 390) and up 120.3 % for the year (6,866 versus 3,117).

    Plus MB has sold YTD 129k cars and SUVs. Will they bump BMW off the pedestal this year.

    Volkswagen's high-mileage, clean diesel TDI models accounted for 24.1 percent of all July sales.

    My favorite the Touareg TDI must have had good sales. Though they did not brag about it.

    Sport utility vehicles Touareg and Tiguan experienced 119.3% and 19.5% sales increases, respectively.

    My bet is, over 50% of those Touaregs were TDI models. Who would want the gas version?

    I am still trying to figure it out with a 2003 TDI and 167,000 miles.

    I just do the scheduled maintenance. There are a host of scheduled maintenace items that I have extended 1. I had the timing belt and water pump done @ 100,000 miles (VW recommended interval). I run currently 30.700 miles OCI's. Fuel filters @ 80,000 to 100,00. Air filters are @ 100,000 miles.

    Unscheduled maintenance, my left front low beam lamp burnt out. I had to get new tires @ 112,300 miles.The coolant sensor was removed and replaced (threw a computer code) .

    I ran another cost comparison agains an 04 Civic and without boring folks it was way higher for the same mileage (110,000 to 120,000 miles)

    Well some people fall off buildings and land on a mattress truck, too. You (and me, with my MINI) have been lucky as well as diligent I think. I haven't had a burp in 80,000 miles--just preventive and pro-active repairs and maintenance. But if you look at the rap sheet on 2003 MINIs, it's sheer carnage out there.

    I never represented it as any thing other than. Also to say that I got the BEST one in the statistical sample would be highly unlikely. Indeed, the chances of getting an average to a below average one is the more statistically likely.

    I betcha you're outside the bell curve though, and I bet I am, too. Were it not so, then 2003 TDIs and 2003 MINIs wouldn't have so many black dots on their Consumer Reports printouts so as to resemble a target hit at close range by a shotgun. :P

    I think there's a couple of factors here.

    Cars are better than they used to be and 200,000 miles isn't all that hard to achieve.

    Word of mouth is more prevalent than just a decade ago. People post like crazy, and the curve of complaints at the NHTSA has to be steep. The failure rate is probably only 2 or 3 %, even on stuff like Odyssey transmissions or CR-V ACs or Toyota gel. Maybe 5% for VW window regulators. :shades:

    We're getting ready to put 5,000 miles on our 12 year old minivan with 158k on it. Back in the day, you'd carry a spare engine if you even considered such lunacy.

    We aren't worried. If the van breaks down, we'll either fix it or buy a clunker to get back home in. Even a clunker is probably good for 50k. :shades:

    You have an interesting point. Sure, EVERY oem and EVERY M and MY has its percentages of "lemons". They also have their share of less than stellar cars. However, on the two examples I used, 04 Civic (gasser) and VW Jetta 2003 TDI the so called "major" tune up (s) are at 110,000 and 100,000 miles respectively, to back up your observation and assertion. So the real question is how many of these cycles (major tune ups) does a customer want to run, Given reasonable care and not being accidented to totalled ?

    The funny thing and I can not prove this, nor is it anything but folklore, but it seems that every mechanic I know would rather work on a clean car than on a dirty one. So if I do one thing to ANY to all of my cars is/are to keep them (components also) as clean as I possibly can.

    One of my neighbors though I was out of my mind when I drove cross country a couple of years back in our (then) ten year old minivan (a 3.8 liter Dodge Grand Caravan) which had over 170,000 miles on the clock when the trip began. The only casualty during the trip; the ground strap between the engine and the body separated and until I replaced it, I couldn't use my cruise control (oh, and the alarm would sound for no reason when the car was locked).

    That said, "back in the day" I got transferred from Los Angeles to Atlanta; back when I could put my complete list of possessions into a 5'x8' trailer. I dutifully loaded up my stuff, hooked the trailer to my 1970 Challenger which had about 230,000 miles on the original 318 (I had found a 340 Six-Pack from a wrecked AARA Cuda which I had in the car for an entire month before the 318 went back in, a month by the way, which featured four speeding tickets) and headed out across the country. I had a casualty on that trip as well, the radiator bailed outside of Albuquerque. :P

    Boredom probably sets in for most people and they want to get something different. Or their needs change.

    There's some grime in my engine compartment, but it's not all that filthy considering the age. Those splash shields must help, not to mention not having leaks. I don't have much interest in scrubbing down the block and risking getting rinse water on the electrical components.

    That is one of the good things about the diesel. Unless you know where the electrical components are (sensitive to water) and set out to make it malfunction, it is pretty seamless to degrease. I normally use a spray bottle of diluted car soap and save the chemical in a aerosol can treatment for once every 6 mo to 1 year.

    Yeah, but why bother? It's not going to make the car run better or last longer and the mechanic isn't going to give you a 20% discount for having a clean engine.

    Remember who you're talking to - I wash the exterior of my cars maybe twice a year. Forget waxing. :)

    And believe me I am learning. I have put almost all my cars on the "extended washing plan" ;) I think the last time I "waxed" (Zaino'd actually) one garaged car was 5 years ago. I did finally break down after 8 mo and washed it.

    I do however subscribe to and :shades: do the 6 mo waxing plan. All this really does is delay to hopefully avoid a paint job in the future.
  • ateixeiraateixeira Member Posts: 72,587

    It also gets an occasional rinse (when it rains).

    Indeed that can be a big deal or NOT. If your car is garaged except for driving, you are for practical purposes, just washing off dirt. On a more extreme example, once a week is forever.

    With all the acid in rain, you should wash it the day after it gets rinsed.

    Rain's probably worse for the paint than spilling diesel fuel on it. :shades:
  • ateixeiraateixeira Member Posts: 72,587
    The other day I saw a Subaru Forester, probably a 2000 model, that I think had never once been washed. The stuff that was caked on the roof had obviously been there for ages, and basically created a brown/orange coating on the whole roof, with pine needles sprinkled on top for effect.

    Yeah anymore the first year one is actually "paying to be the test mule". The MK V Jetta really has been tested now for 2009,2010, 2011.

    Further back VW was able to do the constant improvement mantra for the MK IV Jetta and the 2003 Jetta TDI is still considered one of their better efforts.

    I took a risk on a "first year model" when I bought a used 2003 MINI (well 2002 in some countries) but first I let the original owner make the multiple trips to the dealer to re-build the car. Now it seems to work just fine. Thank you, anonymous hero!

    That's putting it mildly. But hey, mine has been rock solid. I think the car originally had its teething problems, being "all new" and all that, and a very compact, complex design. It's like a 5/8th scale BMW 3-series with FWD.

    Many nice cars started out rocky and got better---C4 Corvette comes to mind, Porsche Boxster, etc.

    I'd be *very* tempted by a MINI diesel countryman wagon. I still find VW scary. :shades: Besides, my friends at Hi-Tec Automotive will work on MINIs but won't touch a VW. (They are a Porsche-Audi shop primarily). I also have a diesel specialist in the area of excellent reputation.

    The Touareg TDI which is near the top of my list, shares a lot with the Cayenne. The new Touareg TDI may be the best SUV on the planet. At least the most capable. BMW spent a ton trying to beat them in the Dakar this year and got beat by 3 Touaregs. None of the other automakers were even close to VW or BMW. VW and BMW took the top 7 slots with a Nissan about 8 hours back. I don't think there is a tougher race in the World. So VW must be doing something right with that vehicle. My guess is it will be a long time before anyone breaks the Touareg TDI Panamericana record set this month from Tierra del Fuego to Prudhoe Bay Alaska of 11 days:17 hours:22 minutes. Porsche needed an SUV and VW supplied the basics.

    It's not every day that two brand new off-roaders turn up at the same time. So is it a coincidence? No. Porsche's Cayenne and Volkswagen's Touareg are brothers - built on the same platform with many shared parts. And we've got them together in the UK for the first time. So is there more than a badge to differentiate these cars?

    Similar external proportions give away the fact that these two cars are related.


    So if you want a Porsche SUV and don't want to spend the bucks for the name get a Touareg and save about $30k.

    The arrival of the new Porsche Cayenne comes at the same time as the new Volkswagen Touareg which makes sense considering the Cayenne is based on the Touareg. Porsche fans should be delighted with the redesign although Porsche purists will still be unhappy until the Cayenne is dead altogether and Porsche returns to its roots. Don't count on it though as the Cayenne is Porsche's best-selling vehicle (shocked? me too) and with VW Group now in control, expect even more vehicles falling outside of Porsche's traditional circle.

    In any case, the new Cayenne arrives looking better than ever as well as the new Touareg. More interestingly, both will come in hybrid trims for the first time and each lose 400 pounds of fat, despite being larger than before. The result is leaner, meaner, and greener machines.

    I would say for sure. One develops a schema for these types of things after seeing many many examples. I have a hard time gauging, as it is a very hard one for one comparison. The only thing "diesel related" that I have seen are many timing belt and water pump changes. But I am sure it is not unlike gasser TB/WP changes.

    Since I have only seem one, the gasser Honda Civic timing belt and water pump AND valve adjustment with attending valve seal R/R, seemed to have many more procedures, took more man hours, seemed more complicated that the diesel TB/WP change, as complicated as that can seem.

    True, true but still the Tourag is only about 65% Cayenne, and the Cayenne engine puts the gasser VAG engine to sleep. (but not the diesel!!)

    I was thinking more about passenger cars when I said that. Forget about that SUV platform-sharing business. One thing they have in common as SUVs is that neither one's body is built in Germany apparently.

    I think it is the same concept, just applied to SUV's. Indeed platform sharing has been going on for a long time from what I can see. As it has unfolded, the VW Tourareg was long before it became a shared platform Porsche Cayenne. There was a lot of upset Porsche purists when the M and Y were considered. I am sure there are still a host of purists that put it on par with the decline of the Roman Empire.

    Oh not to disparage Slovakia or the Czech republic==I was just sayin' that a Porsche passenger car isn't built there, and that Porsche sports cars don't have a lot in common with VW Golfs or Passats.

    My Porsche technician friends do not find VW a familiar universe, but they do of course understand that the Audi-VW world is a lot more similar.

    I think the point was that the VW world is just different enough from the Audi one to make life difficult for them, and they already have a tough job.

    It'll be interesting to see how their shop reacts if/when Audi or Porsche SUVs introduce diesels, as they do not do any diesel work at all and prefer not to.

    I'm sure they *could* do it (smart guys) but I can understand that they do not, at least not at the moment, think of diesels as an enthusiast's type of car.

    Which is why they took on MINI in addition to Porsche and Audi, and not VW.

    The Audi Q7 has offered the same TDI for the last couple years. 36% their big SUV USA sales are diesel. You can buy the Cayenne TDI (same engine) in the EU. Rated 42.8 MPG highway with Imperial gallons. Of the three I like the looks of the Touareg best. And also like the local VW dealer. I have bought several used vehicles from them and they serviced my 2005 Passat TDI. They don't gouge like the luxury car dealers on service. They will gouge just not as bad.
  • ruking1ruking1 Member Posts: 19,826
    There can be no doubt that there is an overwhelming lack of small diesel engine technical expertise. Those that are good to great really have more work than they can handle. I would take it that is also true for gasser specialty folks, albeit there are many more OF them.
  • gagricegagrice Member Posts: 31,450
    Just drooling over the diesels offered in the UK. VW sells a Touareg across the pond with a V8 TDI. Probably would give the gasser Cayenne a run for the money. 5.8 seconds on the 0-62 MPH run. Still get you 38 miles on an Imperial Gallon of diesel.

    Current owners of out-of-warranty diesel passenger cars don't have a lot of options for repairs and service here in the USA. Bringing a VW TDI to a truck stop isn't the best solution.

    I suspect that even at dealerships, one technician has been designated "the diesel guy" and that this is not necessarily regarded as a status position.

    Heavy-Duty pickup trucks are the supercars of the truck world. They have more power than drivers are likely ever to exploit, and bragging rights depend on statistics that are, in practical terms, theoretical.

    While you can’t buy a diesel engine in a mainstream light-duty pickup, heavy-duty pickups now offer propulsion suitable for a tandem-axle dump truck.

    I’m not exaggerating. Ford’s 6.7-liter Power Stroke diesel V-8 packs 400 horsepower and 800 pound-feet of torque; the base engine in a Peterbilt 348 dump truck offers a mere 260 horsepower and 660 pound feet. Does your pickup really need more power than a Peterbilt?
