Vehicle Reference & Fitment Location
This part is removed from and designed to fit the Audi A4 B8 2008-2012 (4-Door Saloon/Sedan & 5-Door Avant/Estate). Below is a reference image of the exact vehicle type this part belongs to, along with the manufacturer logo to guarantee authenticity.
Where is this part fitted?
This Fuse and Relay Box block (including the plastic mount bracket) is located in the Rear Right (Driver's side UK / Passenger side EU/US) Trunk/Boot compartment behind the side trim panel. It distributes power and protects circuits for essential rear vehicle systems, including rear lighting, the fuel pump module, comfort control modules, and rear parking sensors.
Part Details & Symptoms of Failure
Material: High-grade ABS plastic housing, factory original wiring, and premium copper internal terminals designed for safe, high-amperage current distribution.
Common Symptoms of a Faulty Unit:
- Intermittent or complete failure of rear tail lights or brake lights.
- Vehicle cranking but failing to start (often due to a burnt fuel pump relay circuit in this exact box).
- Repeatedly blown fuses in the rear trunk block due to internal shorting or water ingress.
- Loss of function in rear parking sensors or boot lock mechanism.
Why buy a factory original part? Replacing this with an original factory part ensures the correct electrical resistance, perfect fitment, and eliminates the fire risks associated with cheap aftermarket electrical copies. Plus, buying quality recycled parts saves you up to 70% off main dealer prices!
