What goes wrong?
The most common MOT failure reasons are a suspension joint dust cover missing or no longer prevents the ingress of dirt etc, an obligatory rear fog lamp missing, or a front or rear fog lamp inoperative or in the case of a multiple light source more than 1/2 not functioning and the aim of a headlamp is not within limits laid down in the requirements. The top issue, a suspension joint dust cover missing or no longer prevents the ingress of dirt etc, caused 12 failures in 2024. Checking tread depth (1.6mm legal minimum, 3mm recommended) before your test can save an unnecessary fail. You can check prices at Black Circles if you need replacements.
