What Mercedes-Benz GLS failures look like
8 Mercedes-Benz GLS 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 (87.5%), with body, structure and attachments on 4 tests (50.0%) and with registration plates and vehicle identification on 1 test (12.5%). 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.

-
Tyre worn close to legal limit/worn on edge
MOT inspection manual reference 5.2.3, in axles, wheels, tyres and suspension
Recorded on 7 of the 8 tests: 2 failures and 5 advisories or minors.
-

MOT inspection manual reference 6.1.7, in body, structure and attachments
Recorded on 4 of the 8 tests: one failure and 3 advisories or minors.

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.
