I guess I have been lucky, my Passat 2012 TDI has over 100,000 miles, gets 46 mpg combined city/hwy and has not given me any problems so far. My 1966 bug has 8 times the HP (400 @ flywheel ) that it came with and is a joy to drive as my hobby car . I have not experienced any cheap priced parts from any manufacturer in many years,LOL . Quality of VW original factory parts is pretty good , now aftermarket parts are terrible from my experience. Since we have touched on it already I use OEM parts on the Passat for maintenance , just my choice.
