2014 Volkswagen Beetle ProblemsDecreased Power and Fuel Economy from Carbon Buildup
The 2006-2016 Volkswagen Beetle (New Beetle) uses FSI and TSI direct injection engine. 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 Beetle uses direct injection, gasoline does not flow through common carbon buildup areas.
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.
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.
2014 Volkswagen Beetle RecallsPotential Fuel Leak
The fuel rail is a tube that carries fuel to the fuel injectors. A sealing cap on the fuel rail may leak, increasing the risk of a fire. Dealers will replace the affected fuel rail to correct this concern.
A sealing cap at the fuel rail may fail, allowing fuel to leak into the engine compartment, increasing the risk of a fire. Dealers will replace the fuel rail on affected vehicles to correct this concern.
When driving over a rough road or striking a pothole the sunroof glass can break. This would be a distraction to the driver, increasing the risk of a crash. Dealers will replaced the sunroof in affected vehicles to correct this concern.
