VW Touareg is a mid-size crossover SUV produced across three generations from 2002 to the present with both gasoline and diesel engines. First-generation production spanned model years 2003 through 2010, receiving a mid-cycle facelift during its run. The second generation (NF) was produced from 2010 to 2018, after which the third generation (CR) went into production. This guide provides fuse and relay diagrams, locations, and panel assignments for the second-generation Volkswagen Touareg (chassis code 7P; PL72 platform). Fuses related to the cigarette lighters and 12V power sockets are highlighted in bold.
Fuse and relay assignments may vary depending on the vehicle’s model year, engine option, and equipment package.
