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 9,072 advisory comments and 527 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: NEARSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))
Oil leak
VehicleScore MOT data includes 2,207 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))
Brake disc wear
VehicleScore MOT data includes 2,119 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 1,524 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 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: OFFSIDE FRONT COIL SPRING FRACTURED OR BROKEN (5.3.1 (B) (I))
Brake pad wear
VehicleScore MOT data includes 1,144 advisory comments and 177 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 brake pads that were worn or below the inspection limit.
What to inspect
Ask for recent pad replacement and look at the remaining pad thickness.
Example MOT wording: FRONT BRAKE PAD(S) WEARING THIN (1.1.13 (A) (II))
Corrosion
VehicleScore MOT data includes 985 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: FRONT SUB-FRAME CORRODED BUT NOT SERIOUSLY WEAKENED (5.3.3 (B) (I))
Shock absorber issues
VehicleScore MOT data includes 546 advisory comments and 219 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.
What to inspect
Look for oil misting on the damper body and listen for knocks over bumps.
Example MOT wording: NEARSIDE FRONT SHOCK ABSORBERS HAS LIGHT MISTING OF OIL (5.3.2 (B))
Engine warning lamp
VehicleScore MOT data includes 502 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 engine warning lamp that was on, or did not work, during the inspection.
What to inspect
Switch on the ignition and confirm the lamp comes on and then goes out. Ask what was diagnosed if it stayed on.
Example MOT wording: ENGINE MIL INOPERATIVE OR INDICATES A MALFUNCTION (8.2.1.2 (H))
