About This Data

The 2006 Mercedes M L has an MOT pass rate of 53.1% based on 32 tests — below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 88,022 miles on the odometer. With a 46.9% failure rate, the 2006 M L is rated as "Poor" for MOT reliability.

If you own or are considering buying a 2006 Mercedes M L, be prepared for above-average maintenance costs. 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 88,022 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Brakes — 12.5% of failures

Brakes issues account for 12.5% of MOT failures on 2006 Mercedes M L 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).

Noise, emissions and leaks — 12.5% of failures

Noise, emissions and leaks issues account for 12.5% of MOT failures on 2006 Mercedes M L models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.

Tyres — 12.5% of failures

Tyres issues account for 12.5% of MOT failures on 2006 Mercedes M L 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.
