Two things I'd be scared of...make that three. Low mileage tdi, driven by old people, and serviced by dealer. That's a bunged up trifecta there. I'd prefer one with 100k miles driven by Mario Andretti if it was serviced by someone that had a clue what they were doing.
Easy driving will gunk up the intake on a TDI and it's an elaborate process to clean it out. I've heard of dealers charging $500-$600 to do this but I helped a guy (car bought used.....) do it in a few hours. Either way, it can easily be prevented by just driving the thing and not babying it. Not using the correct oil is a big no-no and there's many documented cases where dealers aren't using the correct oil and/or the LOF guy just doesn't know/care. And 37,000km in three years???
I had several major complaints with my short-term '07 Civic. One, the seats just killed me no matter what I did with them. That's a subjective issue and I'm sure most folks don't have that problem or everyone would be ditching them. It was the main reason I bailed on it. Second, the car has zero torque which wore thin on my nerves after awhile. I drive in the mountains a lot and hills that I could accelerate up in 5th gear with the tdi required holy-crap rpms just to try and maintain speed. Got old quick. And finally, driving my typical 75-80mph resulted in a mere 28-30mpg. The good news is the Civic suspension/steering/feel doesn't urge you to drive that fast so you'll likely find yourself putt-putting along at a more leisure speed. I was averaging 35mpg overall keeping it in the 70mph range on the highway. My TDI would average 45mpg with highway speeds in the 75-80mph range and overall far more aggressive driving.
I'm actually looking (more proactive than active) for a used '05.5 or '06 TDI that was owned by a diesel geek. Very hard to find because the types that actually take care of these cars don't usually get out of them unless they're forced. I actually bought my '00 used from a guy that lost his job and just had to sell it.
There are other small fuel efficient choices out there that aren't quite as dull as a Civic. I went the Civic route only because I knew I'd only need it short-term (although I was thinking a year or so...) and had the chance to buy an '07 for under invoice. They typically get close to MSRP for them which worked to my favor a couple months later. Also keep in mind how many miles you drive will calculate into your decision. If you only drive 12k miles a year, the difference between 35mpg and 45mpg is only $200.

I have a 2004 Jetta TDI that had the same issue. They changed the same cooler and the leak stopped so far. It's been over a month. The Thermostat was stuck part way open which was just ducky, too. The issue started about 120 000km.... just as the warranty ran out. Cool stuff eh?

Get the TDI. I bought one used from a small dealer (not VW) in 2003. 46K on it. Did a complete service on it right after I bought it to bring everything up to standard. Still driving it, now has 183K on the odometer. I expect to get 300K out of it. The fluids and filters you can do yourself. Read through the FAQ at TDIclub.com to get an idea of how to do it. TDIparts.com is a good source for what you'll need. Timing belt is the one item you will need done by a mechanic who knows what he is doing.

One other item I should mention. Fuel additive. I use Powerservice Diesel Kleen + Cetane Boost. 4oz in every tank. Available at Wal-Mart. Not expensive and well worth the cost. If you are in an area where the temperature goes below 20F you'll want to use Diesel Supplement. Diesel will gel below 20F, DS has an anti-gel in the blend. If Powerservice not available, check auto parts stores. They should have something comparable.
#1669 of 4777 Sluggish '05 TDI
Jan 25, 2008 (6:13 pm)
I've noticed that over the last few month my '05 TDI (old body) has been very sluggish at RPM's above 2000. I have almost 0 passing power. I tried using fuel additives, which helps but only short term. I've also experimented with fuel from different sources, also with no help. I've got an appt. with the dealership for next week, but just wondering if anyone else has experienced anything similar and what possible causes there could be.
The car has just over 30,000mi on it, and I've kept up on oil changes (with 505.01 approved oil) and even changed the air filter 2 times in the last 20k miles.

leisure suit inlarry, fuel filter? Seems like the 20k fuel filter interval is a bit optimistic - one half-crappy batch of fuel my 06 has no power on the highway, and maybe stumbles too. (is yours stumbling or very smoothly having no power?)
some TDIs were prone to MAF issues that would give the symptom you describe. a test for that is to unplug the MAF - if performance improves than a new MAF is necessary.
also, sounds like your car is under warranty - why not let the dealer have an actual mechanic try diagnosing?

Yes I would agree!! Let the dealer do it under warranty. Let us know what they find out.

Oh, I intend to let the dealer find out the problem, I was just wondering if any other TDI owners had experienced similar issues. I've never had a car with such issues at such relatively low mileage...I mean my '89 Benz with almost 200k miles is still smooth as silk with plenty of power and has had nothing major replaced that I'm aware of.
As I mentioned, I tried some PowerService DieselKleen additive, which helped, but only short term (which was confusing). As for the question about the performance, the car is smooth until I hit ~2000RPM and remains smooth as long as I don't depress the pedal past maybe 1/4....at which point there is no power, the car feels like it does a bit of light jerking, etc. I can't even max out the tach with the car completely out of gear...completely in neutral the engine tops out 500RPM below redline and declines further from there (to up to 1500RPM below redline during the few seconds I was willing to test that theory).
The other reason I'm asking for info from other owners is I want to know somewhat of what to expect from the dealer...mine seems to have a habit of "oh sorry, looks like we can't find an issue" or "well looks like there's been this done elsewhere, sorry but we can't help. Take it back to the other shop" syndrome.
