All 2 Known Issues
On the 2006-2022 Volkswagen Passat 2.0T TSI, the PCV (Positive Crankcase Ventilation) valve diaphragm in the Passat's 2.0T engine tears or deteriorates over time, causing a significant vacuum leak. This leads to rough idle, misfires, and excessive oil consumption. On TSI engines, the PCV is integrated into the valve cover, making it a more involved repair. The failure can also trigger the check engine light and cause a whistling noise from the engine.
Common Symptoms
- Rough idle
- Whistling noise from engine
- Check engine light
- Oil consumption increase
- Misfires at idle
How to Fix
On earlier FSI engines, the PCV valve can be replaced separately. On later TSI engines, the entire valve cover assembly must be replaced as the PCV is integrated. Use only OEM or high-quality aftermarket valve covers with metal PCV internals. Some aftermarket options offer a serviceable PCV to avoid future full valve cover replacements.

On the 2006-2022 Volkswagen Passat, the electric trunk latch actuator on the Passat frequently fails, leaving owners unable to open the trunk with the key fob, interior button, or exterior handle. The actuator motor burns out or the internal mechanism jams. In some cases, the trunk release cable also seizes, leaving no manual override to open the trunk.
Common Symptoms
- Trunk will not open from key fob
- Trunk button on dash unresponsive
- Clicking sound from trunk but no release
- Trunk handle does not release latch
- Intermittent trunk opening
How to Fix
Replace the trunk latch assembly (VW part includes the actuator and latch mechanism as one unit). Access the failed latch by folding down the rear seats and reaching through the trunk pass-through, or by removing the interior trunk trim panel. Lubricate the emergency release cable during replacement to ensure the manual override continues to work.
