Audi S5 MOT Reliability Overview
The Audi S5 is a relatively common sight on UK roads, with 28,652 MOT test results recorded in our database spanning 11 manufacture years. It has an overall MOT pass rate of 83.3% and a failure rate of 16.7%, which is well above the UK average of approximately 37%.
Based on this data, the Audi S5 earns a "Excellent" reliability rating. The average Audi S5 presents for MOT with approximately 59,189 miles on the clock. Manufacture year matters: 2018 models achieve the highest pass rate at 93.2%, while 2015 models have the lowest at 80.5%. This 12.7 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Audi S5 is Tyres, affecting 15.6% of all tests. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. The second most common issue is Suspension at 7.7%. Brakes rounds out the top three at 7.2%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

📉 How Age Affects Reliability
MOT failure rate by vehicle age for the Audi S5. The dashed red line marks when the manufacturer warranty typically expires (3 years).

💡 What does the warranty cliff mean?
The Audi S5 ages relatively gracefully. The failure rate increase of 19% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 16 (22.0% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Audi S5 MOT Data
The Audi S5 is a relatively common sight on UK roads, with 28,652 MOT test results recorded in our database spanning 11 manufacture years. It has an overall MOT pass rate of 83.3% and a failure rate of 16.7%, which is well above the UK average of approximately 37%.
For Audi S5 owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on tyres and suspension for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific S5 is likely to perform.
Tyres — 15.6% of failures
Tyres issues account for 15.6% of MOT failures on the Audi S5. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Suspension — 7.7% of failures
Suspension issues account for 7.7% of MOT failures on the Audi S5. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Brakes — 7.2% of failures
Brakes issues account for 7.2% of MOT failures on the Audi S5. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
