websites attract stories of "failure"
powerfool,
It is no surprise that anyone that has ANY "problem" with ANY car, tool, appliance, etc. will consult the internet and flame the manufacturer these days. You don't hear from the 98-99% that have no problem.
Take a flight, and you will probably reach your destination. In that case, you may not hear from those that don't make it.
So every website devoted to a "thing" will get filled with stories from those few people that have problems. Some of them are really minor, and often user error.
The good news is that there really are 98% of TDI owners out there that have no interest in this website. They'll show up when they have an issue!
I just rolled 18,000miles in 18 months, no problems whatsoever. It's my third TDI. I'd still have the second one if I was smart enough to buy the 6MT. This car is barely broken in, and it delivered 54 mpg in 765 miles in the mountains last summer (42 mpg lifetime average, and I drive agessively all the time), lets me drive by cities with overpriced fuel, and even lets me drive by the next city or town if I want to, to get to lower prices. I do love the range of a 18 gallon tank in a TDI!
I expect problems at some point, because I am realistic. But maybe not. Most people do not have real problems. Most means way over 90% in the long run. Maybe I'll invest in those inline fuel filters in a couple years to protect the fuel system from the potential for fuel pump failure. For now, I just add Optilube and drive.
