Electrical Components
The Audi TT 2006-2014 is equipped with various electrical components, including a power distribution box, fuse box, and relay. The power distribution box is located in the engine compartment and contains high-current fuses that protect various electrical systems in the car. The fuse box, on the other hand, is located in the driver’s side dashboard and contains fuses that protect various electrical components, such as the headlights, wipers, and climate control system.
Fuse Box and Relay Diagrams
The fuse box and relay diagrams in the Audi TT 2006-2014 are essential for troubleshooting and diagnosing electrical issues in the car. The diagrams are located in the owner’s manual or can be accessed online. The fuse box diagram shows the location and amperage rating of each fuse, while the relay diagram shows the location and function of each relay.
To access the fuse box in the Audi TT 2006-2014, open the driver’s side door and locate the plastic panel on the side of the dashboard. Pull the panel to remove it and reveal the fuse box. The fuse box cover has a diagram that shows the location and amperage rating of each fuse. To access the relays, remove the plastic cover on the side of the dashboard near the door hinge. The relay diagram is printed on the cover, showing the location and function of each relay.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
