{"product_id":"2025-audi-s8-service-repair-manual","title":"2025 Audi S8 Service and Repair Manual","description":"\u003cp\u003eThis factory service and repair manual covers the 2025 Audi S8, the performance version of Audi's flagship sedan. An S8 stacks nearly every complex system Audi builds into one car, and the manual is organized to work through them methodically: symptom-led fault trees, then wiring diagrams, connector pinouts, measured value tables, torque figures and full removal and installation sequences. Coverage runs from the V8 driveline and its mild hybrid belt alternator starter system through the automatic transmission and quattro center differential with sport rear differential, predictive active suspension and ride height calibration, all-wheel steering, the high-performance brake system, climate control, the MMI infotainment, and the camera, radar and ultrasonic sensor set behind the assistance functions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e4.0L V8 (DWKA) turbocharged mild hybrid EV-gas (MHEV)\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThe engine letter code is carried forward from the most recent confirmed model year, 2024, and is not verified for 2025. Audi's own erWin portal lists this chassis continuing into 2025, so treat the exact code and output as subject to confirmation against the vehicle data sticker before ordering parts or trusting a specification-critical value.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTrims\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBase Sedan 4-Door\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThe S8 is catalogued as a single grade, so the real variation between cars comes from options: the executive and rear seat comfort packages, carbon ceramic brakes, the Bang and Olufsen advanced sound system and the assistance bundles all change which components and control modules are physically installed. Confirm what your car carries before working through an option-dependent chapter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKnown issues on the 2025 S8.\u003c\/strong\u003e One recall is on federal record for this model year. Audi campaign 90TV, NHTSA number 25V900000, covers a software error that can prevent the rearview camera image from displaying as intended across a wide group of 2019 to 2026 Audi vehicles. That makes the vehicle non-compliant with Federal Motor Vehicle Safety Standard 111 for rear visibility and reduces the driver's view behind the car, raising crash risk while reversing; dealers correct it with a software update at no charge, with owner notification letters mailed in January 2026. No complaints are logged with NHTSA against this model year, so beyond that campaign there is no owner-reported fault pattern to work from, and the manual's guided diagnosis is the right starting point.\u003c\/p\u003e\u003cp\u003eWritten for the 2025 model year specifically, this manual gives an independent workshop or an experienced owner the same structured reference an Audi dealer technician follows, from service intervals and fluid capacities through coding, adaptation, component overhaul and network-level fault diagnosis.\u003c\/p\u003e","brand":"FactoryManual","offers":[{"title":"Default Title","offer_id":48888384028894,"sku":"AUDIS82025SRM","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/4113\/8910\/files\/9324109856990.png?v=1788104644","url":"https:\/\/factorymanual.com\/products\/2025-audi-s8-service-repair-manual","provider":"FactoryManual","version":"1.0","type":"link"}
