2003 Volkswagen Jetta TDI ProblemsPremature Head Light Bulb Burnout and Bulb Harness Failure is Common
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.
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.
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.

Some times check engine light comes on.
Obviously, when I stop and shut engine off it will reset.

When the light comes on, it shows an overrev code.
