Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.

Audio system: The door speakers may rattle due to loose rivets or wiring harness contacting the speakers. Requires new fasteners and rerouting wires. (1999)

Clutch: Due to the return spring falling out of position, the clutch pedal may not fully return and the cruise may not disengage. (1999)

Coolant leak: Backfires due to faulty plugs dislodge the idle control damper from the rear of the VR6 engine causing rough, or no idle. (1999-04)

Engine noise: Due to the throttle cable contacting the engine cover, the throttle pedal vibrates and there is a rapping noise under the hood. (1999-2000)

Hard starting: Diesel engines may be hard to start or run poorly below in cold weather due to fuel clouding. VW recommends using Stanadyne One Shot during the winter. (2000-02)

Rough idle: Backfires due to faulty plugs dislodge the idle control damper from the rear of the VR6 engine causing rough, or no idle. (1999-04)

Vehicle noise: A humming noise when cornering may be coming from the differential. Draining the automatic-transmission fluid and replacing it with synthetic may help. (1999)

This table lists costs of likely repairs for comparison with other vehicles.
