Known Problems

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

Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.

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

A dirty or failed throttle body can cause various drivability issues and illumination of the Check Engine Light.

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.

To avoid sludge accumulation inside the engine, our technicians recommend using the proper synthetic oil with the appropriate oil filter.

Because of issues with the glow plugs and/or the glow plug wiring harness from the control relay, the Check Engine Light may illuminate. Our technicians tell us there is a service bulletin, not a recall from Volkswagen regarding replacement of the glow plugs on 2004-2005 model years only.

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

    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.

    To ensure longevity of the engine, our technicians recommend to follow the maintenance schedule for the timing belt.

    Cars using biofuel typically have problems with injection pump failures; symptoms can include a "no start" condition or external pump leaks.

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

    Oil and carbon tend to build up, creating restrictions in the intake manifold. Symptoms will be loss of power (sometimes severe) and poor fuel economy.

    The water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.
