If you own or are considering buying a 1990 BMW 320i Se Auto, budget for potential repairs before each MOT. 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 113,975 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Seat Belts and Supplementary Restraint Systems — 2.2% of failures
Seat Belts and Supplementary Restraint Systems issues account for 2.2% of MOT failures on 1990 BMW 320i Se Auto 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.
Suspension — 2.2% of failures
Suspension issues account for 2.2% of MOT failures on 1990 BMW 320i Se Auto 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.
Exhaust, Fuel and Emissions — 1.1% of failures
Exhaust, Fuel and Emissions issues account for 1.1% of MOT failures on 1990 BMW 320i Se Auto 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.
