The Land Rover Discovery is a series of seven-seat family SUVs produced by the British automaker Land Rover. Production of the third generation began in July 2004. The vehicle was equipped with petrol engines—a 4.0-liter V6 (219 hp) and a 4.4-liter V8 (300 hp)—as well as a 2.7-liter V6 diesel engine (190 hp). In this article, we take a detailed look at the fuse box diagrams for the Land Rover Discovery 3 (3rd Generation; chassis code L319) for model years 2004, 2005, 2006, 2007, 2008, and 2009.
Here you will find fuse box locations, photos, and diagrams. Fuses for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold.
