About This Data

The 1998 Opel Vectra has an MOT pass rate of 43.8% based on 89 tests — significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 108,407 miles on the odometer. With a 56.2% failure rate, the 1998 Vectra is rated as "Very Poor" for MOT reliability.

If you own or are considering buying a 1998 Opel Vectra, 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 an average mileage of 108,407 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Brakes — 2.2% of failures

Brakes issues account for 2.2% of MOT failures on 1998 Opel Vectra 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 — 1.1% of failures

Body, chassis, structure issues account for 1.1% of MOT failures on 1998 Opel Vectra 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.

Noise, emissions and leaks — 1.1% of failures

Noise, emissions and leaks issues account for 1.1% of MOT failures on 1998 Opel Vectra 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.
