2003 Volkswagen Jetta Problem Reports
RepairPal Verified 2003 Volkswagen Jetta Problem Reports
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.
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.
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.
A coolant leak may develop after oil filter replacement. The coolant o-ring seal can be damaged if the oil filter housing turns when removing or installing the oil filter. The recommended procedure is to hold the filter housing when tightening or loosening the oil filter.
Throttle body failure is not uncommon and can lead to shifting issues with the automatic transmission and other drivability concerns.
Reverse gear failures and noise in the manual transmission models are common.
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.
Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
