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 21 advisory comments and 6 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 FRONT TYRE WORN CLOSE TO THE LEGAL LIMIT (4.1.E.1)
Corrosion
VehicleScore® MOT data includes 13 advisory comments in this group. Seen mainly as an advisory. 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 SLIGHTLY CORRODED (3.6.B.2C)
Suspension bush issues
VehicleScore® MOT data includes 13 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record a worn or deteriorated bush that was not already counted as an anti-roll bar or suspension arm defect.
What to inspect
Listen for knocks and ask which bush the tester named.
Example MOT wording: OFFSIDE REAR TRAILING ARM RUBBER BUSH DETERIORATED BUT NOT RESULTING IN EXCESSIVE MOVEMENT (2.4.G.2)
Steering rack 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.

Check for play at the steering wheel and look for split rack gaiters.
Example MOT wording: OFFSIDE FRONT PLAY IN STEERING RACK INNER JOINT(S)
Oil leak
VehicleScore® MOT data includes 8 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))
Emissions test issues
VehicleScore® MOT data includes 7 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 an exhaust emissions result. They are counted separately from a warning lamp or a catalytic converter note.
What to inspect
Ask for the emissions printout and whether any repair followed a failed test.
Example MOT wording: EXHAUST EMISSIONS CARBON MONOXIDE CONTENT AFTER 2ND FAST IDLE EXCESSIVE (7.3.D.3)
Shock absorber issues
VehicleScore® MOT data includes 7 advisory comments in this group. Seen mainly as an advisory. 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.

Example MOT wording: NEARSIDE FRONT SHOCK ABSORBERS HAS LIGHT MISTING OF OIL (5.3.2 (B))
Lambda sensor issues
