2003 Volkswagen Jetta TDI Problems
Check Engine Light Due to Issues With Glow Plugs/Wiring Harness
Because of issues with the glow plugs and/or the glow plug wiring harness from the control relay, the Check Engine Light may illuminate. Our technicians tell us there is a service bulletin, not a recall from Volkswagen regarding replacement of the glow plugs on 2004-2005 model years only.
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.
Loss of Power Due to Oil and Carbon Build Up in Intake Manifold
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.
Reverse Gear Failures and/or Noise From Manual Transmission
Reverse gear failures and noise in the manual transmission models are common.
Vehicles Using Biofuels May Have Injection Pump Failures
Cars using biofuel typically have problems with injection pump failures; symptoms can include a "no start" condition or external pump leaks.
Correct Maintenance of Timing Belt
To ensure longevity of the engine, our technicians recommend to follow the maintenance schedule for the timing belt.
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.
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.
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.
