What a Rover Princess fails its MOT on, from real DVSA test data, and the part that resolves each item.

Based on 810 MOT tests in DVSA data.

On what we have, about 22.0% fail, most often on brakes, lamps & electrical, suspension, visibility/wipers. For a precise picture of your own car, use the registration check on the home page. Confirm any part against your registration or VIN before buying.

What it fails on, and why

Brakes53.9% of failures

Brake failures cover worn pads and discs, an imbalance between wheels, corroded or scored discs, or a binding caliper. Braking efficiency is measured on a rolling road, so a spongy or pulling brake shows up as a low reading.

Lamps & electrical38.2% of failures

Lighting is the single most common MOT failure and the cheapest to put right. A blown headlight, brake-light or number-plate bulb, a cracked lens, or a headlamp beam that points too high or low will all fail. Most are a two-minute bulb swap.

Suspension28.7% of failures

Suspension failures usually mean a worn or snapped coil spring, a leaking shock absorber, or play in a lower arm ball joint or bush. The tester checks for corrosion, fractures and excessive movement. A broken front spring is one of the most common failures on higher-mileage cars and is a straightforward replacement.

Visibility/wipers25.8% of failures

Visibility failures include torn or smearing wiper blades, a washer jet that does not reach the screen, and chips or cracks in the driver's swept area. Blades and washer fluid are quick, cheap fixes.

Exhaust & emissions18.0% of failures

Exhaust failures cover leaks, insecure mountings and emissions over the limit. A blowing exhaust, a failed lambda reading or a diesel that smokes beyond the limit will fail.

Other16.3% of failures

This covers a range of smaller items, from a non-working horn to a warning light left on.
