Where MOT tests find problems: Opel Astra

What Opel Astra failures look like
3,534 Opel Astra tests on record carry the manual reference DVSA attaches to each defect. The most frequent problems were with axles, wheels, tyres and suspension on 1,977 tests (55.9%), with brakes on 1,616 tests (45.7%) and with nuisance (emissions and noise) on 735 tests (20.8%). 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.
