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, wiper blade missing or obviously not clearing the windscreen and brake pipe damaged or excessively corroded. The top issue, a suspension joint dust cover missing or no longer prevents the ingress of dirt etc, caused 652 failures in 2024.
