About This Data

The 1992 MG B has an MOT pass rate of 76.9% based on 65 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 26,588 miles on the odometer. With a 23.1% failure rate, the 1992 B is rated as "Excellent" for MOT reliability.

If you own or are considering buying a 1992 MG B, 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. Look for fluid leaks under the car near the front wheels. With relatively low average mileage of 26,588 miles, many of these vehicles are still in good mechanical condition.

Steering — 3.1% of failures

Steering issues account for 3.1% of MOT failures on 1992 MG B 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.

Noise, emissions and leaks — 1.5% of failures

Noise, emissions and leaks issues account for 1.5% of MOT failures on 1992 MG B 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.

Road Wheels — 1.5% of failures

Road Wheels issues account for 1.5% of MOT failures on 1992 MG B models. Wheel failures include cracked or severely corroded alloy wheels, missing or loose wheel nuts, and wheels that are insecurely attached. These are safety-critical and relatively rare compared to tyre failures. Typical repair costs: £100–400 per wheel. Pre-MOT check: Visually inspect wheels for cracks, especially around the spokes and rim. Check that all wheel nuts are present and tightened. Look for signs of impact damage on alloy wheels.
