💡 What does the warranty cliff mean?
The BMW 118i Se Auto shows a relatively stable failure rate after warranty — the change of 0% is negligible. Peak failure occurs at age 11 (24.4% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific 118i Se Auto is likely to perform.
Tyres — 9.3% of failures
Tyres issues account for 9.3% of MOT failures on the BMW 118i Se Auto. 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.
Brakes — 8.8% of failures
Brakes issues account for 8.8% of MOT failures on the BMW 118i Se Auto. 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 — 8.1% of failures
Lamps, Reflectors and Electrical Equipment issues account for 8.1% of MOT failures on the BMW 118i Se Auto. 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.
