Our material provides only a general description of the power supply system, relay boxes and fuses in the Audi q5. Check the correct information for your car with your operating book or other relevant information.

Locations of relay and fuse boxes

  • Fuse box and connector for starting the engine from an external power source in the plenum chamber;
  • Fuse box on the right side of the front panel.  The fuses installed in it are indicated on the wiring diagram “SC”. The customer can access these fuses on his own by removing the side cover of the front panel;
  • Relay box and bracket for onboard supply control unit in driver’s side footwell;
  • Fuse / relay box and CAN bus hub in the luggage compartment on the right.  The fuses installed in it are indicated on the wiring diagram “SF”. These fuses can be accessed by the customer by removing the storage compartment in the rear right side of the luggage compartment4
  • Main fuse box on the positive terminal of the battery;
  • CAN bus junction box and hub at the bottom of the left A-pillar;
  • Fuse box on the left side of the front panel. The fuses installed in it are indicated on the wiring diagram “SB”. The customer can access these fuses on his own by removing the side cover of the front panel;
  • Relay and fuse box in the E-Box.
