What Mercedes-Benz 230 failures look like
10,616 Mercedes-Benz 230 tests on record carry the manual reference DVSA attaches to each defect. The most frequent problems were with axles, wheels, tyres and suspension on 5,916 tests (55.7%), with brakes on 3,158 tests (29.7%) and with body, structure and attachments on 1,945 tests (18.3%). 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.
