Tyres — 13.0% of failures
Tyres issues account for 13.0% of MOT failures on the BMW I3 Range Extender. 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.
Road Wheels — 6.5% of failures
Road Wheels issues account for 6.5% of MOT failures on the BMW I3 Range Extender. Wheel failures include cracked or severely corroded alloy wheels, missing or loose wheel nuts, and wheels that are insecurely attached. These are safety-critical and relatively rare compared to tyre failures. Typical repair costs: £100–400 per wheel. Pre-MOT check: Visually inspect wheels for cracks, especially around the spokes and rim. Check that all wheel nuts are present and tightened. Look for signs of impact damage on alloy wheels.
Lamps, Reflectors and Electrical Equipment — 2.6% of failures
Lamps, Reflectors and Electrical Equipment issues account for 2.6% of MOT failures on the BMW I3 Range Extender. 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.
