Where MOT tests find problems: Audi A4

What Audi A4 failures look like
17 Audi A4 tests recorded on MOTindex carry the manual reference DVSA attaches to each defect. The most frequent problems were with axles, wheels, tyres and suspension on 7 tests (41.2%), with visibility on 2 tests (11.8%) and with brakes on 1 test (5.9%). 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, two come up on more than one test:
-
Tyre worn close to legal limit/worn on edge
MOT inspection manual reference 5.2.3, in axles, wheels, tyres and suspension
Recorded on 6 of the 17 tests: one failure and 5 advisories or minors.
-
Windscreen damaged but not adversely affecting driver's view
MOT inspection manual reference 3.2, in visibility
Recorded on 2 of the 17 tests: all of them advisories or minors, so none of them failed a test on its own.
Where there is enough data to compare: Audi Q7 (96 tests), Audi A3 (14 tests), Audi A1 (10 tests), every Audi model (137 tests).
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.
