Where MOT tests find problems: Daf
A test can find problems in more than one category, so the figures above do not sum to 100%. Each percentage is the share of classifiable tests that found at least one defect in that category. Based on 10,651 classifiable tests for Daf.
What Daf failures look like
10,651 Daf tests on record carry the manual reference DVSA attaches to each defect. The most frequent problems were with nuisance (emissions and noise) on 137 tests (1.3%), with axles, wheels, tyres and suspension on 88 tests (0.8%) and with steering on 78 tests (0.7%). A test can fail on more than one thing, and an MOT can be failed on one defect while another is only advised, so these counts do not add up to the number of tests.
Narrowed down from the categories to the individual defects themselves, three come up on more than one test:
-

Clauses are read from the manual reference at the end of every defect on the cached test records, and a defect shown here has to appear on at least two of them before it is named. The site-wide breakdown explains how that works and compares every make.
