Known Problems

The 2006-2016 Jetta 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 Jetta 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. 

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.


One or more power windows may fail. Our technicians tell us this is commonly due to a failed window regulator which will require replacement.

Reverse gear failures and noise in the manual transmission models are common.

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

Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.

Condensation in the heater case may cause a musty odor from the heating, ventilation and AC (HVAC) system after sitting for two hours or more. Our technicians tell us that a cleaner is available for the heater case and the drain system should be checked for debris.

The rear brakes tend to wear out quickly; rotors may need replacement by the first brake job. Our technicians recommend that the brakes be inspected for wear regularly.

Heater core leaks are common in this model, more so if the wrong anti-freeze/coolant is used in the cooling system.
