Reliability & Safety Recalls

Audi A8 2018

Reliability

3/5

The 2018 Audi A8 diesel is a sophisticated executive saloon with strong performance, but the D5 generation (2018+) suffers from costly electrical complexity and diesel-specific issues including DPF regeneration problems and fuel injector wear. Ownership can be expensive due to advanced technology and specialised servicing requirements, though the diesel engine itself is reasonably durable if maintained properly. Reliable used examples are available, but factor in substantial maintenance budgets for long-term ownership.

Known issues

DPF (Diesel Particulate Filter) clogging and forced regeneration cycles causing limp mode and high fuel consumption, particularly on vehicles with low annual mileage
Fuel injector deposit build-up and occasional injector replacement needed around 80,000–120,000 km, resulting in rough idle and starting difficulties
MMI infotainment system freezes, touchpad malfunctions, and software glitches requiring software updates or module replacement
Air suspension compressor failure (models equipped with air suspension) leading to vehicle lowering and loss of ride height adjustment
Diesel Exhaust Fluid (AdBlue) system sensor faults and heater element failures, resulting in warning messages and reduced performance
Transmission shudder and hesitation on the 8-speed tiptronic automatic, occasionally requiring software recalibration or valve body service

Good for

Smooth, economical long-distance cruising with excellent fuel efficiency on motorway driving (6.5–7.5 L/100 km real-world)
Premium interior comfort, advanced technology suite, and sophisticated infotainment (when functioning properly)
Strong diesel engine performance and torque delivery, with reliable core engine durability when properly serviced
Good build quality and attention to detail in trim and materials throughout the cabin

Years to avoid: 2018, 2019
