What Citroen C1 failures look like
1,724,098 Citroen C1 tests on record carry the manual reference DVSA attaches to each defect. The most frequent problems were with axles, wheels, tyres and suspension on 1,003,030 tests (58.2%), with brakes on 687,695 tests (39.9%) and with lamps, reflectors and electrical equipment on 258,495 tests (15.0%). 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.
