About MG Mgf Steptronic MOT Data
The MG Mgf Steptronic is a rare vehicle in the UK, with 46 MOT test results recorded in our database spanning 1 manufacture years. It has an overall MOT pass rate of 58.7% and a failure rate of 41.3%, which is slightly below the UK average of approximately 37%.
For MG Mgf Steptronic owners, these results suggest average reliability — some preparation before MOT can improve pass chances. Focus your pre-MOT checks on brakes and suspension 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 Mgf Steptronic is likely to perform.
Brakes — 39.1% of failures
Brakes issues account for 39.1% of MOT failures on the MG Mgf Steptronic. 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).
Suspension — 34.8% of failures
Suspension issues account for 34.8% of MOT failures on the MG Mgf Steptronic. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Noise, emissions and leaks — 17.4% of failures
Noise, emissions and leaks issues account for 17.4% of MOT failures on the MG Mgf Steptronic. 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.
