If you own or are considering buying a 2021 Mercedes-Benz Sprinter 315 Progressive Cdi, you can expect reliable MOT performance overall.

Brakes — 23.8% of failures
Brakes issues account for 23.8% of MOT failures on 2021 Mercedes-Benz Sprinter 315 Progressive Cdi 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).
Lamps, reflectors and electrical equipment — 17.9% of failures
Lamps, reflectors and electrical equipment issues account for 17.9% of MOT failures on 2021 Mercedes-Benz Sprinter 315 Progressive Cdi models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Tyres — 12.3% of failures
Tyres issues account for 12.3% of MOT failures on 2021 Mercedes-Benz Sprinter 315 Progressive Cdi 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.
