Complete workshop service and repair coverage for the 2025 Audi A8 Quattro, including the long-wheelbase L body. This is the flagship saloon, which means the sheer number of vehicle systems is the real difficulty on any job — adaptive chassis and damping control, rear-axle steering where fitted, multi-zone climate, the assistance sensor set and a dense body electrical layout — and the procedures, wiring diagrams and coding steps here are written to match.

Trim naming and the engine code shown are carried forward from 2024, the most recent independently confirmed model year. Audi's erWin parts portal lists the A8 continuing into 2025, which confirms service data for the badge; exact trim structure and output for 2025 should still be verified against the VIN.
Known issues on the 2025 Audi A8 Quattro. One recall is on federal record for this model year. NHTSA campaign 25V900000 addresses a software error that can stop the rearview camera image from displaying as intended, leaving the vehicle out of compliance with FMVSS 111 on rear visibility; the remedy is a no-charge software update at an Audi dealer, and the campaign spans a wide range of Audi model years rather than this car alone. No complaints are logged with NHTSA for this model year. Because the fix is software, confirm the camera module's software state before diagnosing a blank or delayed rear image as a hardware fault.
Alongside the campaign-specific material sits what long-term ownership actually needs: full maintenance schedules, fluid and lubricant specifications, torque tables, suspension and brake overhaul, body and interior trim removal, and the diagnostic trees for the control modules that make a car like this difficult to work on blind.
