2004 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.

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.

Difficult to Diagnose Electrical Issues Are Typically Due to Ground Issues

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.
