Some of the PD's ('04 thro '06) ate camshafts. Not all though. But a much more involved job to replace those camshafts. Knock on wood, mine is still fine.
Not sure what the latest models are doing, as I haven't felt like replacing mine with a newer model. I'm still peeved over the intake flap failure (twice!) and clutch failure; the turbo failure I'm ambivalent about.
The latest models seem to have problems with high pressure fuel pumps:

this one poster explained what the problem is and nailed it on the head:

I had a 2010 Jetta TDI that I sold after 29,xxx miles when the Mobil stations in Illinois stopped carrying the 5% or under biofuel blends that are required to run these cars in December of 2011. They were the only ones to ever carry D2 or B5 in my day to day life since I bought the car November of 2010 (with a 600 mile tank, you had plenty of time to drive by a tollway oasis). Even before that, most stations in Illinois carried the B20 (5-20% biofuel) blends and the last of the stations finally converted over due to tax incentives from the state of Illinois.
VW explicitly states in the manual that fuel containing >5% biofuel will void the fuel system and emission systems' warranty. The fuel system warranty is voided because the fragile fuel pump doesn't like the biodiesel (may explain the "miss-fillings" stated above instead of gasoline) and the emission system warranty was voided because of the increased regeneration schedule of the active diesel particulate filter that is in the exhaust system and what gives these the "Clean Diesel" name. The biofuel burns "greasier" than the standard D2 diesel and this causes the filter to clog faster and also takes longer to burn off the contaminates during an active regeneration (during the exhaust stroke, the exhaust valve is left open and a small amount of fuel is injected into the cylinder to be pushed down stream and into the DPF where it is hot and will burn off the soot that gets trapped there). This system replaces the Urea injection that BMW, Mercedes, and VW/Audi uses in their 6 cylinder+ diesels.
VW NA was little to no help in the situation. They apologized about the inconvenience of not being able to find the spec'd fuel for the car I bought and then just proceeded to repeat the warranty verbiage saying any other fuel will void the cars warranty. This didn't sit right with me and I decided to sell based on the cost of the components that fail ~$8000 for a fuel pump issue and ~$2000 for a DPF issue. If VW doesn't have the confidence to stand behind their product, why should I? Luckily they hold their value so I didn't really take a bath when I sold it. I'm not very angry with that part of it, but I am still angry about the way they are handling it.
Its a numbers thing.. there is such a small market in the US for diesels (albiet it is gaining solid traction now, until something like this makes news) that it most likely doesn't make sense for VW to make the change in policy/reengineer a solution for the 3 midwest states that run [censored] B20+ fuel.
I laughed when Jalopnik ran a story saying that VW was going to debut the new Beetle TDi in Chicago at the Chicago Auto Show... a market where not one of those customers can buy the fuel to keep their brand new car in warranty. I asked a senior level VW marketing REP (his title escapes me) about this very point at the auto show and he brushed it off as NBD and that they were currently doing testing to determine the effect of B20 and that a statement was on his desk to go out to owners soon. Did anybody receive that? I still get other VW mail sent to me. I took that as, we are testing to see how many components fail in the 36,000 or 50,000 mile warranties. The fact of the matter is, these weren't designed to burn corn and now people have to and it doesn't make financial sense for anyone to do anything about it... Just hope it doesn't affect you.
Honestly, I really enjoyed that car, and the thing I am most [censored] about is that they haven't actually fixed it yet... I would buy another one after this gets properly addressed and they earn my trust back.
