All 1 Known Issues
On the 2006-2024 Volkswagen Jetta, like all EA888-equipped VWs, the Jetta GLI suffers from carbon deposits on the intake valves due to direct injection. Without fuel washing over the valves, oil vapor from the PCV system bakes onto the valve surfaces, gradually restricting airflow. Symptoms typically appear between 40,000-80,000 miles and worsen progressively. The GLI shares this issue with the GTI since they use identical engines.
Common Symptoms
- Rough idle that progressively worsens
- Hesitation or stumble on acceleration
- Misfires and check engine light
- Reduced fuel economy
- Loss of power especially at higher RPM
How to Fix
Walnut blast cleaning every 40,000-60,000 miles is the proven solution. A catch can on the PCV system slows buildup. CRC GDI IVD cleaner sprayed into the intake can provide temporary relief between walnut blasts. Note that fuel additives do NOT work for direct injection carbon buildup since fuel never touches the intake valves.
