If you own or are considering buying a 2004 Mercedes-Benz 280, 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 109,753 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Tyres — 10.0% of failures
Tyres issues account for 10.0% of MOT failures on 2004 Mercedes-Benz 280 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.
Visibility — 5.0% of failures
Visibility issues account for 5.0% of MOT failures on 2004 Mercedes-Benz 280 models. Visibility failures relate to the windscreen, wipers, washers, mirrors, and view-obstructing damage. Cracks in the windscreen swept area, ineffective wipers, or empty washer bottles are common causes. Typical repair costs: £10–300. Pre-MOT check: Check the windscreen for chips and cracks — damage larger than 10mm in the driver's swept area or 40mm elsewhere will fail. Test washers and wipers. Ensure both door mirrors are intact and adjustable.
Noise, emissions and leaks — 5.0% of failures
Noise, emissions and leaks issues account for 5.0% of MOT failures on 2004 Mercedes-Benz 280 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.
