You do seem to have a bit of a dog. Here in UK the recommendation is that the timing belt and tensioners, (plus possibly water pump, whilst it's easily to hand), be changed at 60kmiles/4 years whichever is sooner. In light of your experience it seems like a sensible precaution.
Guess VW are not immune from building the odd bad 'un but they do seem to be pretty rare. Not much comfort to you, though. Sad tale and easy to understand why you wouldn't trust another one.

The real issue here is one of "Maintenance"...Checking of that timing belt is part of regular VW Maintenance...Have you had your TDI serviced at this same dealership on the prescribed schedule? If so; this should be on them...

That was my thought too. Was this timing belt "inspected" per the maintenance schedule?
I find it VERY difficult to beleive that all the teeth on it suddenly just fell off. This kind of thing ususally happens slowley and can be seen at inspection-time.
#1374 of 4777 Article about 2008 Diesels

The attached article is VERY good news. Looks like the high fuel-prices along with the new-wave of clean diesel engines may be timed just right.

I particularly hope the following message makes it to US consumers:
"In the battle with hybrids, the companies pushing the new diesels will certainly point out that hybrids save on fuel consumption only in city driving. Diesel cars consume 20- to 40-per-cent less than gasoline cars under all driving conditions."
#1375 of 4777 cold air for 04
May 12, 2007 (10:59 am)
I just recently purchased an '04 Jetta TDI, and am wondering does anyone have a cold air delivery system for this model? K&N has a replacement air filter, But all cold air apps stop at '03 What is the diff. in the 2 engines? I'm looking to maximize perfomance and efficiency if that is possible. I'm not new to diesels(I've owned a few), only these.,rodekill

Starting in 2004, the TDI engine changed over to a "pumpe duse" engine. This engine uses special cams on the overhead camshsaft to develop VERY high fuel pressure for the injectors.
This also means that your pumpe-duse engine requires VERY special engine oil. Use of any other oil has been shown to destroy the camshaft. (Many VW dealers have been using the wrong oil.... beware)
Now, to answer your question about intake system. There is no need to do anything. The stock system ALREADY uses a cold-air intake system. (air pulled from behind headlight)
Also, if you have not already been warned, do not use an oiled-guaze type of airfilter (such as K&N) The oil from the filter can be sucked onto the MAF sensor and destroy it.
I have no idea why someone would want to spend extra money on an alternative air filtration system that provides absolutely no performance benefit, Filters worse and has been reputed to cause damage to expensive engine components!
#1377 of 4777 Jetta TDI Cloth seats
May 12, 2007 (11:02 pm)
I wanted leather seats when I purchased my 2002 Jetta tdi, but since diesel was rarely available in California I had to settle for biege cloth. Has anyone changed out the cloth interior and had to deal with the airbag in the seat issue?
I'd appreciate any feedback before I make any changes.

Thank you, you've answered my question! Indeed why would you waste money on something that is of no benefit.

I am new to this forum too. We have a 1999 Jetta TDI. The timing belt broke while driving in town. We replaced the belt but can't get the timing correct. Seems you have to have a special tool. Do you mind telling me what you had to pay to have your belt TDI repaired after the belt broke.
What did it damage? I am betting that we will have sustained the same damage and it will give us something else to check under our hood to see why we can't get the thing going. Thanks for any info you can give.
