2009 Volkswagen Jetta TDI ProblemsCheck Engine Light Due to Issues With Glow Plugs/Wiring Harness

Oil and carbon tend to build up, creating restrictions in the intake manifold. Symptoms will be loss of power (sometimes severe) and poor fuel economy.
Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.

when starting the car window goes all the way down. If the car is running and I hit the button for the window to go down it does, but the button will not bring them back up? If I use the key in the door manually it will bring it back up. Is that just the button or something worse?
2009 Volkswagen Jetta TDI RecallsPotential Diesel Fuel Leak
On the 2.0L TDI common rail Diesel engine/clean Diesel engine, fuel injection pulses could coincide with the natural frequency of injector line #2. This resonance creates additional stress on the fuel line. Small cracks could develop in the #2 injector line, resulting in a Diesel fuel leak. A fuel leak always increases the risk of a fire. Dealers will install an improved #2 fuel injector line and install vibration dampers on all of the injector lines to correct this concern. The Volkswagen/Audi recall number is 23J9/V5.
Connectors for a temperature sensor inside the direct shift gearbox (DSG) transmission may have been insufficiently crimped. They could incorrectly read a high transmission oil temperature, and abruptly shift into neutral. The shift position indicator in the instrument panel would begin to flash and the "Depress Brake Pedal" indicator light will be illuminated to alert the driver to apply the brakes. The abrupt shift could lead to a crash. Volkswagen and Audi dealers will reprogram the transmission control module (TCM) with updated software. The recall began October 20, 2009. The Volkswagen recall number is 37E3/S7 and the Audi recall number is 37E5/J7.
