For 2004, all Jetta models get an updated look, optional telematics and a new and more powerful 1.9-liter TDI engine (GL and GLS models only). The 2.0-liter engine is now PZEV-rated, and the GLX trim is no longer available. Also note that you can no longer get the 1.8T engine in GL trim. Besides that, the GLI sedan sports new 17-inch alloy wheels and the Cold Weather Package items (heated seats and washer nozzles) as standard, while the GLS features a standard Monsoon stereo. The wagons get a revised instrument cluster late in the model year, and the sedans get new metallic trim rings around the gauges.
