If you own or are considering buying a 1998 Daimler 4.0 Auto, you can expect reliable MOT performance overall. 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 119,536 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Brakes — 2.4% of failures

Brakes issues account for 2.4% of MOT failures on 1998 Daimler 4.0 Auto models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos.

Seat belts and supplementary restraint systems — 2.4% of failures

Seat belts and supplementary restraint systems issues account for 2.4% of MOT failures on 1998 Daimler 4.0 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.

Tyres — 2.4% of failures

Tyres issues account for 2.4% of MOT failures on 1998 Daimler 4.0 Auto models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
