Audi A1-S1 (8X) (2010-2018) Fuse Box Location & Diagram

The first-generation Audi A1 (8X) holds a special place in the hearts of car enthusiasts, having been produced from May 2010 to October 2018. This remarkable vehicle combined Audi’s renowned engineering with a compact and stylish design, creating an appealing package for drivers. Within this article, we will explore the fuse box diagrams of the Audi A1 models released in 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017 and 2018. These diagrams serve as valuable resources, offering detailed information on the locations of the fuse panels inside the car. By referring to these diagrams, owners can easily access and maintain their fuses, ensuring optimal functionality. Additionally, this article provides insights into the assignment of each fuse, enabling a better understanding of the fuse layout and its corresponding functions within the Audi A1.

Checking and replacing fuses

The electrical circuits in the car are protected from short circuits by fuses. This significantly reduces the likelihood of damage due to electrical problems.

To check a fuse, look at the silver strip inside the fuse. If the strip is broken or melted, replace the fuse. Make sure to replace the faulty fuse with a new one of the same size and amp rating.

Fuses of the same amp rating can be temporarily taken from another location if the original fuse has blown. Replace the fuse as soon as possible to ensure proper protection.

Note:

  • Before replacing a fuse, make sure the key has been removed from the ignition and that all services are turned off and/or disconnected.
  • When replacing a blown fuse, it is important to use only a fuse with the correct amp rating. Using a fuse with a rating different from the specified one can lead to dangerous electrical system overload.
  • If a fuse with the proper amp rating continues to blow, it indicates a problem in the circuit that needs to be resolved first.

  1. I’m not sure why my fuel pump’s fuse burned out, but thanks to your guide, I managed to locate and replace the fuel pump relay within minutes. Maybe you know what could have caused the problem of the fuse burning out?
