The warranty on new TDI is about worthless if the high pressure fuel pump fails. VW dealerships are blaming it on fuel and not covering it.
If I were to get another TDI, it probably would be an 03 model. My brother who didn't sell his 06 TDI is in for a large repair. His cams are shot and his Dual mass flywheel (DMF) is shot..both at 62k miles.
Stories like this tend to steer me away. I wish auto manufactures made small diesel engines with the reliability of a Dodge Cummins.
160,000 miles on my '02 Jetta wagon and I've had VERY few issues of any sort with it outside of normal maintenance and wear and tear items. No doubt it will go 250,000 or even 300,000 easily.
The '06 you mention would be a PD (pumpe duese) engine - and indeed they have turned out to be less than stellar and ABSOLUTELY REQUIRE that the proper oil is used. 10W-30 from the local grease shop ain't gonna cut it and will ensure the early demise of the cam. The DMFs have not been a widespread problem but it just seems to depend on driving style and/or luck of the draw. I've driven with people who could "operate" a manual transmission but really didn't know how to "drive" a manual. These people tend to go through clutches. I bought my first car ('80 Rabbit) back in '86 with ~80K on it and it needed a clutch. I only put about 60K on it with no further clutch issues. Then I had a '93 Saturn SL and put 156K on it with the original clutch and now 160K on my TDI on the original clutch.
The high pressure fuel pump "issue" I'm only a little familiar with. But that one smells like defective pumps and of course, VW tries to weasel out due to "bad fuel". VW had a similar problem several years ago on the PD motors with the fuel pumps (that were part of the vacuum pump) leaking fuel into the crankcase until the engines hydrolocked or blew up. They also had a string of failures where the engine would dump it's guts into the oil pan when a balancer shaft failed - likely due to defective shafts from a "low cost supplier" (also on PD motors) - and that's only on the Dodge Caliber (and fugly Jeep twins) that are exported with the VW diesels.
VWs ownership (and German car ownership in general) seems to be more highly variable than others. You cannot ignore or shortcut maintenance and a simple part failure (one-way clutch on the alternator pulley) can trash other things (tensioner) quickly if not noticed. Many car owners are clueless and wouldn't notice a change in engine noise or car vibration unless a wheel was falling off or a rod was coming through the block. By that time it's usually too late and now a lot more is trashed and $$$ to fix compared to catching the failing part early.
I am not a VW fanboy and cuss at much of the "engineering" VW has done. But my TDI has been amazingly solid (and still is squeak/rattle/rust free) after 9 years of "rust belt" driving. I do all my own work, which has saved me countless dollars, and know the work is done properly (another strike against VW - the dealers absolutely suck at proper service).
