If you own or are considering buying a 1998 Peugeot 406 Sx Turbo Diesel, budget for potential repairs before each MOT. Before your MOT, pay particular attention to lamps, reflectors and electrical equipment: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test. With an average mileage of 103,483 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Lamps, Reflectors and Electrical Equipment — 64.5% of failures
Lamps, Reflectors and Electrical Equipment issues account for 64.5% of MOT failures on 1998 Peugeot 406 Sx Turbo Diesel models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Suspension — 58.1% of failures
Suspension issues account for 58.1% of MOT failures on 1998 Peugeot 406 Sx Turbo Diesel 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 — 32.3% of failures
Brakes issues account for 32.3% of MOT failures on 1998 Peugeot 406 Sx Turbo Diesel 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).
