What Renault Master failures look like
737,250 Renault Master tests on record carry the manual reference DVSA attaches to each defect. The most frequent problems were with brakes on 354,382 tests (48.1%), with axles, wheels, tyres and suspension on 303,583 tests (41.2%) and with lamps, reflectors and electrical equipment on 224,688 tests (30.5%). 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.
