What goes wrong?
The most common MOT failure reasons are a suspension pin, bush or joint excessively worn, the strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired and lambda coefficient outside the default limits or the range specified by the manufacturer. The top issue, a suspension pin, bush or joint excessively worn, caused 95 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. 31.1% of Ls400 failures could actually strand you: fractured springs, engine faults, exhaust problems. Another 24% are safety issues where the car still drives but shouldn't, such as worn brakes, corroded brake pipes, and steering wear. Breakdown cover may be worth considering for this model. When it does fail, the average repair bill is around £155.
