Most reported 2001 Volkswagen Jetta TDI problems
Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.
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 and noise in the manual transmission models are common.
Cars using biofuel typically have problems with injection pump failures; symptoms can include a "no start" condition or external pump leaks.
To ensure longevity of the engine, our technicians recommend to follow the maintenance schedule for the timing belt.
Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
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.
