About This Data
The 1997 Jaguar Xj8 has an MOT pass rate of 62.5% based on 3,716 tests — around the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 100,755 miles on the odometer. With a 37.5% failure rate, the 1997 Xj8 is rated as "Average" for MOT reliability.
If you own or are considering buying a 1997 Jaguar Xj8, budget for potential repairs before each MOT. Before your MOT, pay particular attention to suspension: 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. With an average mileage of 100,755 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Suspension — 3.3% of failures
Suspension issues account for 3.3% of MOT failures on 1997 Jaguar Xj8 models. 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.
Brakes — 1.4% of failures
Brakes issues account for 1.4% of MOT failures on 1997 Jaguar Xj8 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 — 0.8% of failures
Noise, emissions and leaks issues account for 0.8% of MOT failures on 1997 Jaguar Xj8 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.
