About This Data

The 1999 Mercedes E 55 has an MOT pass rate of 66.3% based on 1,449 tests โ€” slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 113,367 miles on the odometer. With a 33.7% failure rate, the 1999 E 55 is rated as "Good" for MOT reliability.

If you own or are considering buying a 1999 Mercedes E 55, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to suspension: 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. With an average mileage of 113,367 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Suspension โ€” 1.9% of failures

Suspension issues account for 1.9% of MOT failures on 1999 Mercedes E 55 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: ยฃ200โ€“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.

Noise, emissions and leaks โ€” 1.0% of failures

Noise, emissions and leaks issues account for 1.0% of MOT failures on 1999 Mercedes E 55 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: ยฃ100โ€“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 โ€” 1.0% of failures

Tyres issues account for 1.0% of MOT failures on 1999 Mercedes E 55 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: ยฃ50โ€“200 per tyre. Pre-MOT check: Check tread depth with a 20p coin โ€” 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.
