I have a 2009 VW Jetta TDI with 6 speed manual transmission and 74,000 miles. The exhaust flap or valve has been sticking open on and off. It usually resets itself, however I have noticed I am getting about 3 to 4 mpg better mileage when the flap is stuck open. I turn the key on and off and use a code scanner to clear/reset the error code PF-047 which comes on when the flap sticks open. I plan to get it replaced under the VW warranty but just have not had the time to get to the dealer. Any problem letting this go on for a while?
