Driving 5,000 miles per year you can't justify the payback in the short term with fuel savings. That said, get what you want to get. If you plan on keeping your TDI for a long time like most owners do, it will pay for itself in the long run and provide many years of service if properly maintained. Are you certain you can justify buying a new TDI (or new anything) with that little driving though? At 5,000 miles per year, most anything will do.....just an observation.kmil said:I couldn't help but borrow from the great Bard (Thank you England). I live in the USA and as of now only drive around 5000 miles per year. Most of my driving (+95%) is in town and not highway miles.
How much sense, if any, would it make to get the 08 Jetta Diesel instead of the regular gas model? From what I've read it would appear that highway miles are best for a Diesel. Put another way, would mostly city driving be "bad" for a Diesel and if so why.....OR....would it make any difference at all?
Assuming the Diesel option is going to cost and extra $1,500 dollars in the US would it "pay" to get a Diesel considering my current 5000 miles/city driving a year? Nevertheless, I'm fairly certain that Diesel may well be a good investment from the resale point of view. I've read a number of posts where a Diesel owner (Jettas) saw their resale value increase. I guess what I'm trying to do is "convince" myself to go the Diesel route. What say you???
Your reasoning is sound, too bad it does not pan out in the real world. The TDI actually reigns supreme on the highway as well, because its torque enables it to easily push the car through the air at a much lower RPM. That's why most TDIs can still get over 40 MPG with ease even at high 80+ speeds, but the comparable 2.0L gas engine in the same car drops to around 20 to 23 at best. I've had both, the TDI beats the crap out of the gasser MPG wise everywhere.fancy_dancer said:The biggest advantage of a diesel is at idle: it uses only enough fuel to keep the engine ticking over. A gasoline engine must run stoichiometric and uses MUCH more fuel per hour at idle. That's why semi's can get away with idling overnight.
The faster you drive (or, the more power that you demand from your engine) the less the advantage of diesel. If you had two 90 BHP Golfs (or similar) running flat-out, one gas and the other diesel, the diesel would still be more efficient but not by nearly as much as in city driving.
You hit the nail right on the head. Resale. Let me run a few numbers by you, from the Canadian blackbook; all are for a 2002 Jetta GLS, no additional options, manual trans, 100,000 km on the odo:kmil said:Assuming the Diesel option is going to cost and extra $1,500 dollars in the US would it "pay" to get a Diesel considering my current 5000 miles/city driving a year?

Still april 2008 as far as Ive heard. It'll be a 2009 model.Peoria_TDI said:I have a friend who is wanting to buy a 2008 Jetta TDI. Has anyone been able to confirm the release date? I apologize if this has already been covered, didn't feel like reading through 431 posts. TIA.
It still might take few months until all the diesel stations are "washed" clean of any remaining "old" diesel. By the time the new Jettas come around next April, I doubt, that the intake clogging will still be an issue. In Europe, where they had ULSD 'clean diesel', for many years, they hardly know of such a problem with the intake clogging.kmil said:Thanks for the article. It is much appreciated. I have a question though I'm sure you can't give us/me a definitive answer as the car is too new.
However, would you or anyone else have an idea as to how much faster the engine "warmup" might be compared to the 2006 Jetta Diesel. The reason I ask is that most of my driving would be done "in town" as opposed to highway miles. I also understand that too much in town driving is not the best thing for a diesel as it allegedly causes some kind of "carbon" buildup in the engine.I had heard that if the new '08 diesel warmsup faster it would be "better" for the engine. I guess what I'm trying to ask is that if indeed the new diesel warms up faster than the previous engine........then would that have less of a negative effect on "gook" buildup in the engine. Pls email me at: email@example.com
Thanks for your time and attention!
The new German diesels are so stuffed full of high tech improvements, it boggles my mind and I do believe, that many issues, as they are discussed here in these forums, will be a thing of the past.
Of course, with lots of new built-in technology, there is exposure to new vulnerability......beta testing is human nature, we would still be in the stone age.......
I hope it never warms up.kmil said:Wait4TDIPD:
Thanks for your reply but you seemed to have NOT opined on my question. Please read email again and you'll see that I was asking about what difference, IF ANY, might there be on the WARMUP of the NEW '08 TDI in COMPARISON to the previous ('06 VW TDI). Basically it would seem to me that if the new '08 TDI warms up FASTER than the '06 the the problem on potential intake clogging might be greatly REDUCED! What say you? Once again, thanks for your time and consideration!
Or break the timing belt. Can't blame that on the head, however.bhtooefr said:They are made out of aluminum, and they haven't been failure-prone since 1982. Just don't overheat them.
That's usually a "Code 18" failure mode... in other words the cause is sitting 18" behind the steering wheel.IndigoBlueWagon said:Or break the timing belt. Can't blame that on the head, however.
