 I bought my Passat TDI for the fuel economy, reliability and longevity of the diesel engine. Ive never had a more unreliable vehicle than this one including a few couple hundred dollar vehicles when i was a kid. The turbocharger failed. The fuel pump failed. The exhaust flap failed. Then the new turbo was damaged by the dealer. Then the clutch broke. The transmission synchros broke. Then the heater core plugged. Now the oil cooler is plugged. Almost every major component has failed and lead to enormous repair bills.
