2025 Audi S e-tron GT Service and Repair Manual

This service and repair manual is written for the 2025 Audi S e-tron GT, the S-tier version of Audi's battery-electric grand tourer. It is structured for electric-vehicle work from the start: high-voltage safety and de-energizing procedure, the traction battery and its cooling circuit, the front and rear drive units, the charging system with its AC and DC paths and charge port hardware, thermal management, regenerative and friction braking, the adaptive suspension, the low-voltage supply, MMI, and the camera, radar and ultrasonic sensors behind the driver assistance functions. Every area carries symptom-led fault trees, wiring diagrams, connector views, measured value tables, torque figures and removal and installation steps.

Powertrain

• Battery-electric grand tourer, the S variant of the e-tron GT range
• Audi's own erWin parts catalog lists the S and RS e-tron GT chassis under code F8P from 2025, which confirms the badge for this model year

Specific output figures for this car are not independently confirmed, so none are stated here. Read the drive unit configuration, battery variant and software level from the vehicle data sticker and from control module identification before you follow any specification-sensitive procedure or order a part, and treat exact trim naming as subject to confirmation as well.

Trims

• Premium Plus
• Prestige

The two grades differ in lighting, seat, audio, suspension and driver assistance content, and that equipment decides which modules, sensors and actuators are physically installed. Match the option-dependent chapters to your build sheet before tracing a circuit or ordering a component.

Known issues on the 2025 S e-tron GT. Work reported symptoms through the manual's guided diagnosis instead of pattern-matching from the earlier e-tron GT range. On any high-voltage Audi, confirm the low-voltage battery state of charge and the DC-DC converter output before condemning control modules, and check the high-voltage interlock loop end to end when the car will not activate its drive system or start a charge session.

Written for the 2025 model year specifically, this manual gives an independent workshop or a competent owner the same structured reference an Audi dealer technician works from, covering maintenance schedules, coding and adaptation, component overhaul and network-level fault diagnosis. High-voltage work must only be carried out by someone qualified to do it, with the system isolated and verified de-energized first.
