These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.
Corrosion
VehicleScore® MOT data includes 24 advisory comments and 2 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.
These MOT comments record corrosion the tester could see on the body or structure. Corrosion already named on a spring, brake, or other component is counted with that component.
What to inspect
Inspect the underside, sills, and subframe for heavy corrosion, especially where an advisory mentions it.
Example MOT wording: OFFSIDE REAR BRAKE PIPE CORRODED, COVERED IN GREASE OR OTHER MATERIAL (1.1.11 (C))
Oil leak
VehicleScore® MOT data includes 19 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record an oil leak noted by the tester. Shock absorber misting is counted as a damper issue, not as an engine oil leak.
What to inspect
Look under the engine for fresh oil, and check the oil level.
Example MOT wording: OIL LEAK, BUT NOT EXCESSIVE (8.4.1 (A) (I))
Parking brake faults
VehicleScore® MOT data includes 11 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.
These MOT comments record a parking brake that did not hold well enough or had a component defect.
What to inspect
Test that the parking brake holds the car on a slope and releases cleanly.
Example MOT wording: PARKING BRAKE EFFICIENCY BELOW REQUIREMENTS (1.4.2 (A) (I))
Brake disc wear
VehicleScore® MOT data includes 10 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record brake discs that were worn, scored, pitted, or corroded.
What to inspect
Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Example MOT wording: FRONT BRAKE DISC WORN, PITTED OR SCORED, BUT NOT SERIOUSLY WEAKENED (1.1.14 (A) (II))
Coil spring issues
VehicleScore® MOT data includes 10 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record coil springs that were corroded, fractured, or otherwise defective. They are counted separately from shock absorbers.
What to inspect
Look for a broken or heavily corroded spring and compare the ride height on both sides.
Example MOT wording: NEARSIDE REAR COIL SPRING CORRODED (5.3.1 (B) (I))
Anti-roll bar issues
VehicleScore® MOT data includes 4 advisory comments and 4 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.
These MOT comments record wear or damage in the anti-roll bar, its links, or its bushes.
What to inspect
Listen for a knock when driving over uneven ground at low speed.
Example MOT wording: OFFSIDE FRONT ANTI-ROLL BAR LINKAGE BALL JOINT HAS SLIGHT PLAY (5.3.4 (A) (I))
Shock absorber issues
VehicleScore® MOT data includes 4 advisory comments and 4 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.
These MOT comments record shock absorbers or dampers that were leaking, misting, or insecure. A light misting of oil on a damper is not an engine oil leak.
