The leading cause of MOT failure for the 1992 Lancia Thema is Noise, emissions and leaks, responsible for 5.1% of failures. 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 range from £100–1,000+. Tyres is the second most common issue at 5.1%. Brakes follows at 1.7%.

About This Data

The 1992 Lancia Thema has an MOT pass rate of 66.1% based on 118 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 123,638 miles on the odometer. With a 33.9% failure rate, the 1992 Thema is rated as "Good" for MOT reliability.

If you own or are considering buying a 1992 Lancia Thema, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to noise, emissions and leaks: 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. With an average mileage of 123,638 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Noise, emissions and leaks — 5.1% of failures

Noise, emissions and leaks issues account for 5.1% of MOT failures on 1992 Lancia Thema 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.

Tyres — 5.1% of failures

Tyres issues account for 5.1% of MOT failures on 1992 Lancia Thema models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.

Brakes — 1.7% of failures

Brakes issues account for 1.7% of MOT failures on 1992 Lancia Thema 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).
