These cars are not for maintenance ignorant Toyota owners, if you buy one of them new, you need to be a car freak and literally smarter than the dealership you bought it from.
To make these cars go the long haul to 200,000 miles, it helps to have owned it from the start. You have to follow its maintenance schedule like a religion. For example, dealers may suggest that you use full synthetic oil when changing every 5000 miles, but most people don't want to spend the extra money, so they go cheap on oil changes with bad long term results, (the engine will sludge up and seize, resulting in Big $$ repair costs). You should only be using 5W-40 Full Synthetic oil, every 3000 to 5000 miles, (this data is in the owners manual). You should also be using an extended length oil filter (a Mann or Mahle filter are preferred).
There are many VW forums out there that will help you with maintenance issues like VWvortex, but you have to actually spend the time to read stuff.
One big problem with these cars is the automatic tiptronic transmission. If you bought the car new, the dealer would tell you that the transmission was "sealed" for the life of the vehicle and the transmission fluid was never meant to be changed, well, for them, the life of the vehicle meant a 4 year 50,000 mile warranty, so they didn't care about what happened to the car after then. Turns out, new owners should have been changing that transmission fluid at 30K, 60K and so on.
The vehicle also has some built in design problems, like its wiring harness that lays on top of the valve cover unshielded. The wiring harness cracks over time with heat and cold cycles (you'll notice the car missing or perhaps running rough) and needs be replaced, it's not a expensive part, but it's $300 or so in labor.
Also its Bremi coils aren't the best designed product, so eventually one of them will start to fail, causing the car to run rough, you'll just need to replace all 4 coils and you'll be back in business.
Another big maintenance item is the timing belt, VW says it will last until 105,000 miles, but don't believe them, it really needs to be changed at around 80,000 miles, some would change it even sooner at 60,000 miles. Neglecting your timing belt could cost you about $3000 in engine repairs.
I follow maintenance schedules like a freak, so our car, (that we bought new) has 130,000 miles on it and is still going strong, although the transmission is shifting hard between 1st and 2nd gear, (my mistake was that I listened to my VW dealership, who said the transmission was sealed, never needing maintenance), now I have to do some research to learn how to solve the problem with the least amount of $$ damage.
While car was under its extended warranty of 85,000 miles we had to replace the following:
Air conditioner compressor pump,
Broken window, dropped inside door and broke, fixed under recall.
Front strut bumpers.
Normal maintenance stuff that we've replaced since then:
Timing belt, timing belt tensioner and water pump.
All brakes and rotors.
Main accessory belt and its tensioner.
We're on its third set of tires.
General tune up stuff, flushed all fluids..
At 130,000, most of the front suspension components are worn out, so that stuff is going to be replaced.
1) Don't believe much of anything the dealer tells you and above all, don't trust them.
2) Find a good private, local mechanic that really knows VW's that will let you bring in your own parts.
3) Take personal responsibility for your own property, and do lots of homework about the proper maintenance on your vehicle.
