2002-2005 Volkswagen Touareg fuse box diagram

The first-generation Volkswagen Touareg (7L) made between 2002 and 2005, you’ve come to the right place. These diagrams show you where the fuse panels are inside the car and explain which fuses and relays are assigned to each function. It’s helpful if you need to replace a fuse or understand how the electrical components are organized in your Touareg.

Cigar lighter (power outlet) fuses in the Volkswagen Touareg are the fuses #1 (Cigarette lighter), #3 (12 V socket rear right, rear cigarette lighter), #5 (12 V socket 2 front Centre console, 12 V socket 3 rear) in the Left Instrument panel fuse box.
