there is some question as to whether the fuel injection system in the TDI is worth the price tag
because it was only recently put into production in the latest models, there is no good historical data to prove its reliability
people are concerned about its ability to last over the years 50% because it is a product of innovation and 50% because the fundamentals behind its operation are a throwback to a time when the fuel quality afforded it
basically it is a high-rpm, high-pressure system which depends almost entirely on the fuel itself as a lubricant
this was never a problem before the EPA was instituted to ruin vehicles, fuels, etc.; today's fuels can be very questionable
