About This Data
The 1998 Jaguar XJ has an MOT pass rate of 64.5% based on 14,782 tests — around the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 100,063 miles on the odometer. With a 35.5% failure rate, the 1998 XJ is rated as "Average" for MOT reliability.
If you own or are considering buying a 1998 Jaguar XJ, 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 100,063 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Suspension — 5.0% of failures
Suspension issues account for 5.0% of MOT failures on 1998 Jaguar XJ 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 — 2.6% of failures
Brakes issues account for 2.6% of MOT failures on 1998 Jaguar XJ 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).
Body, chassis, structure — 2.2% of failures
Body, chassis, structure issues account for 2.2% of MOT failures on 1998 Jaguar XJ 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.
