About This Data
The 2005 BMW 520d M has an MOT pass rate of 65.3% based on 481 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 106,188 miles on the odometer. With a 34.7% failure rate, the 2005 520d M is rated as "Good" for MOT reliability.
If you own or are considering buying a 2005 BMW 520d M, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to tyres: 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. With an average mileage of 106,188 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Tyres — 4.8% of failures
Tyres issues account for 4.8% of MOT failures on 2005 BMW 520d M 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.
Brakes — 4.4% of failures
Brakes issues account for 4.4% of MOT failures on 2005 BMW 520d M 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).
Suspension — 2.9% of failures
Suspension issues account for 2.9% of MOT failures on 2005 BMW 520d M 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.
