More features

• Direct OEM Replacement: This is a direct replacement for the Audi/VW OEM battery fuse with part number 4F0915519​ (also listed as 6R0915519). It is a 250 Amp​ high-current fuse designed to protect the vehicle's main electrical system from catastrophic overload or short circuits, preventing potential fire hazards.
• Critical Safety Component: This fuse is located directly on the positive battery terminal​ and protects the main power feed to the vehicle's fuse/relay panels. A blown fuse will cause complete electrical failure (no-start, no power). Replacing it restores all vehicle functions.
• Wide Audi & VW Compatibility: Fits a broad range of Audi and Volkswagen models built on the MLB/MLB Evo and PQ platforms, including: Audi Sedans/Coupes: A3, A4, A5, A6, A7, A8, S4, S6, S8, RS3, RS4, RS5, RS7 Audi SUVs: Q5, Q7, allroad Audi Sports Cars: TT, TT RS, TTS Volkswagen: Passat (B6/B7), Touareg
• Easy DIY Replacement: Always disconnect the negative battery terminal first.​ The fuse is located on the positive battery clamp/terminal. Use a 10mm socket to remove the terminal bolt, swap the fuse, and reassemble. Crucial:​ Ensure the vehicle is completely powered down before starting.
• Diagnosis & Prevention: If this fuse is blown, a major short circuit likely caused it​ (e.g., faulty starter, alternator, or damaged wiring). It is strongly recommended to have the vehicle professionally diagnosed to find and fix the root cause before installing a new fuse to prevent immediate re-blowing.
