I had one of the first TDI Passat's out of the VW Chattanooga plant. The only issue I had with it was the radiator supplier didn't clean the flux off the radiator tank where it was soldered together and the flux clogged up the heater core. That was a vendor QC issue not VW's. It was a 45 min fix. Other than that I had no issues with the car for 80K miles when VW bought it back for dieselgate. I wish I had kept the car. So I am not concerned about the quality of the cars coming out of TN.
