With that said, you need to concentrate on making the piston-rings seal as best as they can BEFORE the cylinder-walls glaze. It is nearly imposible to seal the rings after the walls are glazed. This type of engine tends to burn oil and get poor MPG.
Many words have been written about how to seal the rings to the cylinder-walls. Basically you need to use the turbocharger so the rings are forcefully pushed into the cylinder-walls. This means AGGRESSIVE ACCELLERATION - followed by DECELLERATION. You can start doing this after about 5,000 miles.... it takes over 20,000 miles to acheave full cylinder compression in a TDI.
You do this with a fully-warmed engine. While on highway in 5th gear allow vehcile to slow to about 40MPH....then use FULL THROTTLE to get up to about 70MPH ... followed by decel back to speed-limit. Then drive normally for at least 20 minutes to allow temp to stabilize.
Another way to do this is to use FULL THROTTLE ACCELLERAION from a stop to get up to 70MPH ... followed by decel back to speed-limit...again followed by cooldown period.
You should do this AT LEAST 4 times per tank of fuel as long as you own the vehicle. There are benefets to keeping the turbocharger clean too!
I personally seated the rings in my TDI using this process and enjoy up to 56MPG. (and have spreadsheet of every drop of fuel to prove it!) At over 100,000 miles, my engine is finally "loosened up" and running very well.
re: SMOKING -- probably dirty injectors, yep.
"To get the rankings, Strategic Vision calculated the index based on survey questions about reliability, vehicle characteristics, dealership experience, styling, interior and exterior design and their overall perception of initial quality."
when it comes to strictly reliability surveys, I like to look at least 2-3 years in the field before judging a car. Sometimes early production glitches get fixed, so first year record doesn't look as good as second year and beyond---and other times, a car starts out great but problems develop in 40-50K miles.
04/05 passat TDI had decent grunt but also a now-apparent design flaw - chain driven oil pump apparently fails on *every* one of the 04/05 passat TDIs, and now VW sells a replacement gear-system instead. it's $2000+ job, and usually not under warranty. !
As far as TDI & redlining, i agree there's no reason to ever get close to redline or even yellow line, but seems like the consensus is that it's good to give the TDI a daily blast up to a decent rpm to let it the exhaust "blow its nose" of accrued soot in an old/DIRTY diesel, and let the turbo spread its 'vanes' .
for the new/CLEAN jetta TDI diesel, similarly blasting onto the the highway should help to ensure that the DPF can do its occasional cooking thing.
I have been running 2 cars (03 Jetta TDI 119,000 miles /04 Civic 87,000 miles) side by side (even I will say it is an apples to oranges comparison), for easily... 5 years. Needless to say, the "make up" has been off (glitz and glamor) for a very long time, if it ever was on.
Hopefully for obvious reasons, @ similar mileage (87,000 miles) , BOTH have been completely and utterly reliable. Given both cars' similarities and differences, I have been completely happy with both.
The wear items on the Civic are consumed at roughly 2 x the rate of the Jetta.
This is interesting in that the Jetta is run harder and faster on the non commute portion and is 435 #'s heavier. I would dare say if I ran the Civic like I do the Jetta, the consumption rate would be more like 3x to maybe 4x's higher !!?? It would also probably be a drag to the 38-42 mpg we now post.
One explanation could be "higher" initial quality. Another could be the Civic engineers designed it that way: given that most folks are almost brainwashed about the Civic's quality before most folks even own one.
@ 75% RPMS or 3,825 rpms (of 5,100 redline) that would accomplish the goals.
(sorry to hear about the $2k chain driven oil pump issue).
Is this normal for new TDIs or did mine miss out on something that is supposed to be there?
I can never get the keys from the wife, as she drives it to work most of the time.
Tell me your not using "Gas". I must assume you are using "diesel" or your car would not be running.
I know it's a tough habit to break, but after getting our TDI, I have had to make sure when talking to the wife I use the word diesel or fuel, never "gas" or I might end up with a tank full of it.
What I have noticed recently is a loss of power when I reach the 2800 RPM band. More noticeable up hills. Interestingly enough, I am not getting any warning from the MIL or any other lamp on the dash. I know they are working as they light up on engine start as perscribed. This sort of thing happened at just over 100,000 km a few years ago and was told it was my mass air flow sensor (but I did get a MIL warning on my dash when this happened). That was replaced under the emission warranty.
Usually, anytime something is wrong, some lamp would tell me so on the dash. Not his time. Due for an oil change next week - I'll ask the mechanic - just wondering if anyone has had a similar problem?
I plan to run this car to 500,000 - I enjoy driving it very much.
Also would not hurt to hook up to VagCom and check your IQ (Injection Quality).
Additionally, if you have never cleaned your intake-manifold. I would put money on the fact that your intake-manifold needs to be removed and cleaned. (It is a KNOWN issue with running North-American crappy diesel in an EGR-equiped engine.)
A question for those far more experienced with diesels than myself, I can't recall what I've read/heard about max mileage and when you can expect to see it. If I'm not mistaken, is it around 40-50K?
When I bought my Passat TDI in 2005, I was able to find ARCO stations that only sold ULSD in CA. It ran great for the 8000 miles I kept it.
The Diesel Particulate Filter (DPF)
What is it?
I can not speak for the 2009, as I totally researched about (15-5 ppm) ULSD and the most likely damage would be to the (very expensive) DPF. On the road, I once put a B5 Chevron tank full, but I will stay with ULSD D2.
Overall, it is way too new to tell and while there have been incidences of "mis fueling" (LSD) none have had LSD steady diets. Moreover, there have been no 2009 TDI LSD damage reports.
Off topic, there has been RUG to PUG, D2 mixture damage reports. :lemon: So... do NOT try this at home !!!
The 2003 TDI was designed for ULSD (15-5 ppm) but (mine) was run most of its operating life on LSD ( 130 ppm CA & 500 ppm 49 state) (till Oct 2006 to present- ULSD)
The EPA and CARBs even as they professed lesser emissions, controlled it to tactically FORCE.... MORE emissions.)
@ 100,000 miles the TB/WP change was due so of course took the opportunity to look at and possibly CLEAN/change out the intake manifold and clean the EGR. The guru pronounced both good to go (to 200k or next 100k interval) The camshaft original tool markings was also GOOD news !!! For all intent and purposes I can tell no (SOTP) difference/s between LSD (both CA/49 state) and ULSD (15-5 ppm)
Diesel ON !!
So you have been burning LSD or worse for the past 100,000 miles and your engine is still squeeky clean?
That seems to fly in the face of those with gunked up manifolds and frozen turbos. The common diagnosis has always been that the high sulfer fuel was the culprit.
What's your system for avoiding that huge problem that some diesels have?
The "preventative"procedure: drive the turbo diesel as designed. (aka, slightly more aggressively I can get ultra specific, if it doesn't bore anybody) The spin off:.... let the mileage fall where it may.
It turns out my problem was an almost totally blocked intake manifold (they showed me the gunked up manifold) - could hardly get my small pinky finger through!. They removed the intake, steamed cleaned it, replaced the EGR valve and the mass air flow sensor. They checked the VNT actuator and nothing was wrong with it. The work came to about $700 Canadian - not bad - it was less than I would have expected at the dealer. Forgot how poweful my car was as I got used to the loss of power for the last couple of months! It is nice to easily accererate up hills again.
Thanks to the (American) EPA and CARBS for the needed but unnecessary cleaning !! :mad: :lemon:
On a lighter note, here's a VW video that I think you'll get a blast out of...literally.

I think if I had to replace the Civic, I would probably lean toward the Polo. @ 61 mpg diesel, that is reason enough to zip around with. It would make the Civic @ 38-42 mpg look like a gas guzzler.
You are absolutely correct, VW already does know how to make small cars.
Reading the Jetta forums for older models is sometimes like listening to a report of the ravaging of Europe by the Mongols. :P It's interesting that the TDI enjoys a better reputation isn't it? Makes you realize that most of the problems are with the gas engines---timing belts, engine sludge, ignition coils, cam cover leakage, (V6) etc. Chronic issues that don't seem to go away.
Essentially that was the decision fog I walked through with the 2003 Jetta TDI. So I looked at the issues common to both and concluded it was a fairly decently made machine, aka, I was willing to take the risk.Or, at the very worst, able to be mitigated.
I am not sure why they have the engineering, reliability, durability problems they do with their GASSER engines !!! ??? Indeed in a bit of heresy, I would not get a current VW with a gasser engine!!?? Suffice to say while the TDI has its own peculiar issues, it has been a trooper.
In addition, I did not use a VW spec oil (after the break in factory fill @ 5,000 miles) & have run 25,000 OCI's since. At 119,000 miles, the thing has literally been trouble free. Fuel mileage is 48-52 in a point a to b commute. I can get 44 to 62 mpg @ will. This thing was made to cruise @ lower autobahn speeds. As you know, we do not observe autobahn speeds past 70 mph and 80 mph in TX: God Bless TX. :lemon: Oil consumption has been at 1/4 to 1/2 qt (8 oz to 16 oz) per 20,000 miles.
As a side bar, the 2009 TDI has been flawless, EVEN with the DSG. Oil consumption is NIL/nada/ZIP, but we are only at 8,000 miles.
I can make a (university engineering ) joke here, but it might be lost on most folks and offensive to others.
Volkswagen is planning to purchase all of sports carmaker Porsche, which has run into massive financial problems linked to its overly ambitious plan to take control of VW. The attempted takeover, which had been financed using loans, ultimately failed because of the credit crunch and ensuing liquidity problems that almost saw Porsche go bankrupt.
SPIEGEL has obtained information that Volkswagen is planning a complete takeover of beleaguered sports carmaker Porsche in a series of two transactions. The company is planning the imminent purchase of 50 percent of Porsche shares and will purchase the remaining shares in the Stuttgart, Germany-based automobile manufacturer in a second step. Once completed, Porsche will become the 10th brand in the stable of Volkswagen, the world's largest carmaker.
DPA
Porsche headquarters in Stuttgart: VW has won the power struggle between the two companies.
VW's move to acquire Porsche follows a power struggle between the companies. Porsche had sought to buy VW through complicated loan transactions that collapsed when the sports carmaker's liquidity dried up as a result of the credit crunch. It has already been reported that Wolfsburg-based VW would purchase 49.9 percent of Porsche, but SPIEGEL has learned it is now planning a complete acquisition in a second purchase of shares.
The deal envisions a payout to Porsche Automobil Holding of €8 billion ($11.3 billion), enabling it to pay off the bulk of its crippling debts. VW is also considering acquiring Porsche's Salzburg-based network of dealerships from its family owners, a move that could raise an addition €3 billion for Porsche.
Under the deal, the Porsche and Piëch families, Porsche's shareholders, would obtain 50 percent of the shares in the merged VW-Porsche company. The western German state of Lower Saxony would maintain its 20 percent holding in the company and the door would be open for the emirate of Qatar to purchase between 14.9 percent and 19.9 percent of the company's shares.
German news agency DPA reported Friday that the Porsche and Piëch families had agreed to accept the Volkswagen deal. Reuters also reported the deal was now backed by Porsche supervisory board chairman Wolfgang Porsche, who had fought to maintain Porsche's independence from VW.
SPIEGEL also reported on Friday that Porsche's current CEO, Wendelin Wiedeking, would step down and that the families had agreed to replace him with Porsche production chief Michael Macht.

Wolfgang Porsche denied the report on Friday evening, rebuffing "speculation" that Macht would succeed Wiedeking. Wiedeking, he said, remained head of Porsche AG and Porsche Holding. Deputy chairman of the board and works council chief Uwe Hück also defended Wiedeking. "Wiedeking is chairman of the board and he will continue to be so," he said.
Nevertheless, Wiedeking appears to be preparing for his exit. DPA reported this week that he has hired prominent labor lawyer Jobst-Hubertus Bauer to help him negotiate a severance package, a development also reported by the Financial Times Deutschland newspaper.
Wiedeking has reportedly been a client of Bauer's for some time now. The labor lawyer has negotiated golden handshakes for several top managers totaling millions in recent years. It is reported that Wiedeking could be up for a deal worth more than €100 million.

But the numbers in this example would be telling.
You have a choice of selling 100 (TDI) vehicles. You have to go thru a costly and lengthy certification procedure and put on an extra 3,500 compliance system and it might take you some time to sell the 100 vehicles in the US markets.
Now in China, way faster and less costly certification procedure and not having to put the extra 3,500 in the compliance system and they are literally sold before shipment !!. What would be YOUR choice !!??
The 911 Carrerra S already has 385 hp and 310 #ft !! Using the same ratios as the VW Jetta TDI that would make a 911 TDI 266 hp and 448 # ft !!?? Or 45% more # ft !!!
