Use our detailed year-by-year breakdown and failure analysis below to understand how your specific E250d Avantgarde A is likely to perform.
Exhaust, Fuel and Emissions — 16.7% of failures
Exhaust, Fuel and Emissions issues account for 16.7% of MOT failures on the Mercedes E250d Avantgarde A. 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.
Lamps, Reflectors and Electrical Equipment — 16.7% of failures
Lamps, Reflectors and Electrical Equipment issues account for 16.7% of MOT failures on the Mercedes E250d Avantgarde A. 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 — 10.0% of failures
Tyres issues account for 10.0% of MOT failures on the Mercedes E250d Avantgarde A. 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.
