If you own or are considering buying a 2018 BMW I8, 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 relatively low average mileage of 23,511 miles, many of these vehicles are still in good mechanical condition.
Tyres — 4.0% of failures
Tyres issues account for 4.0% of MOT failures on 2018 BMW I8 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 — 0.8% of failures
Visibility issues account for 0.8% of MOT failures on 2018 BMW I8 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.
Identification of the vehicle — 0.8% of failures
Identification of the vehicle issues account for 0.8% of MOT failures on 2018 BMW I8 models. Identification failures relate to the Vehicle Identification Number (VIN) and registration plate. The VIN must be permanently displayed and legible, and the registration plate must meet British Standard formatting. Typical repair costs: £10–50. Pre-MOT check: Ensure the VIN plate is visible and legible (usually in the windscreen or under the bonnet). Check that number plates are clean, undamaged, and use the correct font and spacing.
