If you own or are considering buying a 1998 Opel Astra, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to seat belts and supplementary restraint systems: Pull each seat belt fully out and check for fraying, cuts, or fading. Ensure each belt retracts smoothly and the buckle clicks securely. Check the pre-tensioner warning light on the dashboard. With an average mileage of 111,467 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Seat belts and supplementary restraint systems — 0.5% of failures
Seat belts and supplementary restraint systems issues account for 0.5% of MOT failures on 1998 Opel Astra models. Seat belt failures include frayed or cut webbing, faulty retractors, buckles that don't latch properly, and missing or damaged anchorages. All fitted seat belts must be functional. Typical repair costs: £50–200 per belt. Pre-MOT check: Pull each seat belt fully out and check for fraying, cuts, or fading. Ensure each belt retracts smoothly and the buckle clicks securely. Check the pre-tensioner warning light on the dashboard.
Steering — 0.5% of failures
Steering issues account for 0.5% of MOT failures on 1998 Opel Astra models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
Noise, emissions and leaks — 0.3% of failures
Noise, emissions and leaks issues account for 0.3% of MOT failures on 1998 Opel Astra 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.
