About Mercedes 190 Mk2 MOT Data
The Mercedes 190 Mk2 is a rare vehicle in the UK, with 31 MOT test results recorded in our database spanning 0 manufacture years. It has an overall MOT pass rate of 35.5% and a failure rate of 64.5%, which is significantly below the UK average of approximately 37%.
For Mercedes 190 Mk2 owners, these results suggest above-average failure risk — thorough pre-MOT checks are recommended. Focus your pre-MOT checks on exhaust, fuel and emissions and brakes for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific 190 Mk2 is likely to perform.
Exhaust, Fuel and Emissions — 41.9% of failures
Exhaust, Fuel and Emissions issues account for 41.9% of MOT failures on the Mercedes 190 Mk2. 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.
Brakes — 38.7% of failures
Brakes issues account for 38.7% of MOT failures on the Mercedes 190 Mk2. 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 — 29.0% of failures
Lamps, Reflectors and Electrical Equipment issues account for 29.0% of MOT failures on the Mercedes 190 Mk2. 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.
