What goes wrong?
The most common MOT failure reasons are tyre tread depth not in accordance with the requirements, a suspension pin, bush or joint excessively worn and a brake lining or pad worn below 1.5mm. The top issue, tyre tread depth not in accordance with the requirements, caused 933 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. If you need repairs before retesting, sites like BookMyGarage let you compare local prices.

How serious are these failures?
Not all MOT failures are equal. 17.8% of 508 failures could actually strand you: fractured springs, engine faults, exhaust problems. Another 41.1% are safety issues where the car still drives but shouldn't, such as worn brakes, corroded brake pipes, and steering wear. When it does fail, the average repair bill is around £112.
The warranty question
A 3-year-old 508 passes its MOT 85.3% of the time. By 7 years old that drops to 76.9%, a 8.4 percentage point fall, right as the manufacturer warranty runs out. At 10 years it's down to 72.1%. With an average repair bill of £112 when things go wrong, an extended warranty can make sense on a 508 that's past its third birthday.
Fuel type matters
Petrol versions pass at 86.3% while Electric/Diesel versions pass at 67.8%, a 19 percentage point gap.
