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.
Tyre wear
VehicleScore MOT data includes 58 advisory comments and 13 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 tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.
What to inspect
Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.
Example MOT wording: OFFSIDE REAR TYRE WORN CLOSE TO THE LEGAL LIMIT (4.1.E.1)
Corrosion
VehicleScore MOT data includes 44 advisory comments and 11 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: NEARSIDE REAR BRAKE PIPE SLIGHTLY CORRODED (3.6.B.2C)

Test that the parking brake holds the car on a slope and releases cleanly.
Example MOT wording: PARKING BRAKE: EFFICIENCY BELOW REQUIREMENTS (3.7.B.7)

Oil leak
VehicleScore MOT data includes 12 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.
