About This Data
The 1992 Ford Sierra Xr 4x4 has an MOT pass rate of 54.4% based on 57 tests — below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 42,050 miles on the odometer. With a 45.6% failure rate, the 1992 Sierra Xr 4x4 is rated as "Poor" for MOT reliability.
If you own or are considering buying a 1992 Ford Sierra Xr 4x4, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to brakes: 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). With relatively low average mileage of 42,050 miles, many of these vehicles are still in good mechanical condition.
Brakes — 5.3% of failures
Brakes issues account for 5.3% of MOT failures on 1992 Ford Sierra Xr 4x4 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).
Exhaust, Fuel and Emissions — 5.3% of failures
Exhaust, Fuel and Emissions issues account for 5.3% of MOT failures on 1992 Ford Sierra Xr 4x4 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.
Body, Structure and General Items — 3.5% of failures
Body, Structure and General Items issues account for 3.5% of MOT failures on 1992 Ford Sierra Xr 4x4 models. 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.
