Known Problems

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

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.

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

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.

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.

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 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.

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.

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

One or both head lights may not work due to premature head light bulb burnout and/or bulb harness failure. Care should be taken to inspect the head light harness connector for damage when replacing bulbs. Damaged connectors should be replaced.

Reverse gear failures in the manual transmission models are common.

Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
