2002 Volkswagen Jetta Problems
High Mileage Automatic Transmissions May Have Shifting Problems
Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.
Power Window May Fail Due to Window Regulator
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/or Noise From Manual Transmission
Reverse gear failures and noise in the manual transmission models are common.
Difficult to Diagnose Electrical Issues Are Typically Due to Ground Issues
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.
Engine Overheating Due to Damaged Water Pump Impeller
A damaged water pump impeller may cause an engine overheating condition. Our technicians tell us the repair should include replacement of the water pump, thermostat, and flushing the cooling system.
Flasher Relay Failure Can Cause Erratic Turn Signal Operation
Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
Coolant Leak From Oil Filter Housing O-ring
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.
Check Engine Light Due to Ignition Component/Engine Coolant Temperature Sensor Failure
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.
Engine Oil Leaks
Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.
Mass Air Flow Sensor May Fail
The mass air flow (MAF) sensor may fail, resulting in drivability issues and/or illumination of the Check Engine Light.
Check Engine Light Due to Dirty/Failed Throttle Body
A dirty or failed throttle body can cause various drivability issues and illumination of the Check Engine Light.
One or Both Head Lights May Not Work
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.
Inspection of Water Pump and Timing Belt
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.
Use correct oil/filter to prevent sludge accumulation
Inspect Brakes at Every Service as Rear Brakes Wear Out Quickly
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.
