Focus your pre-MOT checks on lamps, reflectors and electrical equipment and exhaust, fuel and emissions 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 Ng is likely to perform.
Lamps, Reflectors and Electrical Equipment — 22.5% of failures
Lamps, Reflectors and Electrical Equipment issues account for 22.5% of MOT failures on the MG Ng. 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.
Exhaust, Fuel and Emissions — 20.0% of failures
Exhaust, Fuel and Emissions issues account for 20.0% of MOT failures on the MG Ng. 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.
Body, Structure and General Items — 15.0% of failures
Body, Structure and General Items issues account for 15.0% of MOT failures on the MG Ng. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
