2009 Volkswagen GTI Problems

No Start after Refueling and Popping Noise from Trunk

Popping sounds from the rear of the vehicle may be heard moments after starting the engine, or when slowing to a stop. This noise is from the leak detection pump filling the fuel tank with air, and releasing to retest the system when it finds a fault. The sequence of faults identifying this issue are as follows:

  • Succession of loud pops from rear of vehicle
  • Pops go away, and fuel economy decreases 
  • Check engine light illuminates
  • OBD trouble code P2404 and/or P0441 is stored
  • Engine will not start after refueling (must crank for over 30 seconds)
  • Vibration when slowing to a stop

The cause is a valve which is mounted on the front of the intake manifold, commonly called the N80 valve, or EVAP system purge valve. The valve is designed to open under specific circumstances, but a worn valve will remain open at all times, preventing the pressurization of the fuel tank. 

Correction of the issue is to replace the N80 valve with the latest revision.

Clunking Noise from Floorboard Under Acceleration

Drivers of the Volkswagen GTI, R32, and Golf R may experience a clunking noise associated with acceleration from a stop, or downshifting for hard acceleration. This will also be accompanied by a light impact sensation under the drivers feet. Drivers may also notice unexplained changes to their front end alignment while driving. 

This issue is commonly called " VW Subframe Clunk", and is caused by the gradual stretching of the bolts that secure the subframe to the vehicle. The subframe is a large plate that secures to the bottom of the engine bay, and connects the body of the car to the engine and suspension. Over time, the bolts that secure the subframe stretch, allowing the subframe to move and hit the bottom of the car when accelerating.

There are many aftermarket kits that can be installed to correct the issue, and Volkswagen has issued a correction including better bolts, and spacers which fit between the subframe and the car.

Driver Door Electronic Switches Work Intermittently

The driver door wiring loom cracks and degrades with time due to weathering and frequent opening and closing of the door. This problem affects the normal operation of all electronic components of the door including, but not limited to:

-Electric Windows

-Electric Door Locks

-Trunk Release

-Fuel Filler Door Release

-Speakers

-Interior Lights Stay On at All Times

-Keyless Locks

-Power Side Mirrors

-Alarm

The correction for this issue is to replace the driver side door wiring harness. For security purposes, the doors can be locked with the key. The interior lights should be shut of manually, and through the multi function display in the gauge cluster to prevent battery drain.

2009 Volkswagen GTI Questions

My transmission has a noise upon engagement of the clutch. what is the solution? (1 answer)

This noise is not consistant. It sounds like something is not being lubricated in the transmission. Most likely it occurs when the car is cold. VW wants $89.00 to diagnose the problem. Thanks.

2009 Volkswagen GTI Recalls

Volkswagen Recalls Certain 2006–2010 Models Due to a Possible Fuel Leak

Volkswagen is recalling certain 2007–2009 Jetta, Jetta Sportwagon, Golf, and Rabbit, as well as 2006–2010 Beetle and Beetle Convertible vehicles equipped with a 2.5L gasoline engine due to a possibly damaged fuel supply line. Under hood fasteners may chafe against the fuel supply line, resulting in a fuel leak. Fuel leakage, in the presence of an ignition source, could result in a fire. Dealers will perform vehicle-appropriate inspections and repairs in order to protect the fuel supply line from chafing damage.

Automatic Transmission Shifts Into Neutral Without Warning

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.
