How these numbers are made
From the DVSA anonymised MOT data for 2023: every normal MOT test of a car in Great Britain, with its mileage and every advisory and failure item. For each first-use year (pooled with the years either side) and 20,000-mile band we count the share of tests where a part was recorded, and compare it with the same share for every car of that age at that mileage. A cell is shown only with 300 or more tests. Advisories are tester notes, not failures. Figures describe UK-market cars; engines and equipment can differ in other countries.
