Used Audi S7

What to know before buying: Audi S7

From 4 video reviews and 1 press test · updated 23/09/2026

What the reviews say

• The 2025 S7 combines sleek styling, a large cargo hold and sporty handling, although it is less aggressive than the Mercedes-AMG GT53 or BMW 8-Series Gran Coupe.[5]one source
• The 2019 C8 with the 3.0-litre diesel feels more like a lavishly equipped, comfortable A7 with strong brakes and adaptive suspension than a focused sports car.[2]one source
• In the 2015 S7, the 4.0-litre twin-turbo V8, seven-speed dual-clutch transmission and all-wheel drive work well together; the reviewer especially praises its sound and driving fun.[4]one source

Typical faults

• Pre-2021 C8 cars were reported to suffer starter-generator failures: a battery warning could appear and leave the car unable to restart. A revised component was introduced later.[1]one source
• The C8's eight-speed ZF transmission can develop clogged solenoids, causing hesitation or a jolt on the shift from first to second gear.[1]one source
• The heavy hatch's gas struts wear over time; on the reviewed C8 at 68,000 km, the lid could occasionally sag by roughly five centimetres when parked on a slope.[1]one source

  68 000–68 000 km

Which engine and version to take

• The European and Korean C8's 349-hp 3.0-litre TDI is described as more stable and less maintenance-sensitive than the 3.0- and 2.9-litre petrol alternatives, suiting comfortable long-distance use.[2]one source

What to check at the inspection

• On a pre-2021 C8, verify that the starter-generator is the latest revision and scan for stored 48-volt-system or battery faults.[1]one source
• During the test drive, check the first-to-second shift: hesitation or a jolt may indicate contaminated ZF solenoids. Review the transmission-fluid service history as well.[1]one source
• Open the hatch, including while parked on a slope, and confirm that the heavy lid remains fully raised; sagging points to weakened gas struts.[1]one source
• Before purchase, read the complete fault history and compare its recorded mileages; the inspected 2021 diesel still retained diagnostic records of earlier events.[3]one source
• Check for even tyre wear, inspect the brake discs and pads, and establish whether an engine-oil service is due; these items already needed attention on the inspected 2021 car at 40,000 km.[3]one source
