If you own or are considering buying a 2021 Fiat Auto-sleepers, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to lamps, reflectors and electrical equipment: 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. With relatively low average mileage of 10,621 miles, many of these vehicles are still in good mechanical condition.
Lamps, reflectors and electrical equipment — 20.5% of failures
Lamps, reflectors and electrical equipment issues account for 20.5% of MOT failures on 2021 Fiat Auto-sleepers models. 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.
Noise, emissions and leaks — 2.6% of failures
Noise, emissions and leaks issues account for 2.6% of MOT failures on 2021 Fiat Auto-sleepers models. 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.
Non-component advisories — 2.6% of failures
Non-component advisories issues account for 2.6% of MOT failures on 2021 Fiat Auto-sleepers models. Non-component advisories issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
