An accumulation of dust inside the body of the turn signal switch can cause a partially closed circuit, which results in the turn signal relay intermittently clicking at a high rate. Spraying a small amount of residue-free electronic contact cleaner (such as Electrosolve) inside the turn signal switch can resolve this problem. The turn signal relay is not the root cause of this problem, but may be damaged by it.

Newest 2002 Volkswagen Jetta Problem Reports
Vehicles with 2.0L engines consume oil at an unusually high rate. VW specifies the oil consumption should not be a cause for concern unless it exceeds 1 quart per 1000 miles.
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.
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.
An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.
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.
