About This Data
The 2015 Audi S3 has an MOT pass rate of 90.8% based on 1,016 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 55,884 miles on the odometer. With a 9.2% failure rate, the 2015 S3 is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 2015 Audi S3, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to brakes: 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). At 55,884 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Brakes — 3.1% of failures
Brakes issues account for 3.1% of MOT failures on 2015 Audi S3 models. 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).
Tyres — 1.7% of failures
Tyres issues account for 1.7% of MOT failures on 2015 Audi S3 models. 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 — 1.2% of failures
Suspension issues account for 1.2% of MOT failures on 2015 Audi S3 models. 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.
