Known Problems

Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. To help prevent this issue from occurring, the cam follower should be inspected every 10,000 - 15,000 miles. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. 

To correct this issue one or all of the following will need replacement: the camshaft, high-pressure fuel pump, and/or the cam follower.

 

The mass air flow (MAF) sensor may fail, resulting in drivability issues and/or illumination of the Check Engine Light.

Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.

Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.

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. 

The engine may develop an overheating condition due to a damaged water pump impeller. Our technicians tell us the repair should include replacement of the water pump, thermostat, and flushing the cooling system.

Due to an ignition component and/or engine coolant temperature sensor failure, the Check Engine Light may illuminate. Replacement of the failed component will be necessary to correct this concern.

The 2006-2017 Volkswagen Passat uses FSI and TSI direct injection engines. These engines are subject to carbon buildup in the intake system which can cause power loss, OBD codes and a check engine light, and a rough idle. In normal engines, the engine is cleaned by the gasoline flowing through the injectors and into the intake system, however, since the Passat uses direct injection, gasoline does not flow through common carbon buildup areas. 

Possible trouble codes include: P0300P0301P0302P0303P0304, P0305, P0306.

The solution is to remove the intake manifold and professionally clean the intake manifold, intake ports on the cylinder head, and the intake valves. This may need to be done in as few as 20,000 miles. 

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.

    The Check Engine Light may illuminate due to a faulty oxygen sensor and/or coolant temperature sensor. Proper diagnoses will be required to confirm the fault.

    The 2006-2016 GTI uses FSI and TSI direct injection engines. These engines are subject to carbon buildup in the intake system which can cause power loss, OBD codes and a check engine light, and a rough idle. In normal engines, the engine is cleaned by the gasoline flowing through the injectors and into the intake system, however, since the GTI uses direct injection, gasoline does not flow through common carbon buildup areas. 

    Possible trouble codes include: P0300P0301P0302P0303P0304.

    The solution is to remove the intake manifold and professionally clean the intake manifold, intake ports on the cylinder head, and the intake valves. This may need to be done in as few as 20,000 miles. 

    The Check Engine Light may illuminate because of evaporative (EVAP) emission failures and/or intake manifold vacuum leaks.
