If you own or are considering buying a 2018 Morgan Plus 4, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to steering: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump.

Steering — 2.3% of failures
Steering issues account for 2.3% of MOT failures on 2018 Morgan Plus 4 models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
Brakes — 1.0% of failures
Brakes issues account for 1.0% of MOT failures on 2018 Morgan Plus 4 models. 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).
Noise, emissions and leaks — 1.0% of failures
Noise, emissions and leaks issues account for 1.0% of MOT failures on 2018 Morgan Plus 4 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.
