If you own or are considering buying a 2009 Mercedes 515, 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). With an average mileage of 238,128 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Brakes — 2.6% of failures

Brakes issues account for 2.6% of MOT failures on 2009 Mercedes 515 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 — 2.6% of failures

Lamps, reflectors and electrical equipment issues account for 2.6% of MOT failures on 2009 Mercedes 515 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.

Identification of the vehicle — 1.3% of failures

Identification of the vehicle issues account for 1.3% of MOT failures on 2009 Mercedes 515 models. Identification failures relate to the Vehicle Identification Number (VIN) and registration plate. The VIN must be permanently displayed and legible, and the registration plate must meet British Standard formatting. Typical repair costs: £10–50. Pre-MOT check: Ensure the VIN plate is visible and legible (usually in the windscreen or under the bonnet). Check that number plates are clean, undamaged, and use the correct font and spacing.
