BMW M240i common MOT failures and failure rate
What a BMW M240i fails its MOT on, from real DVSA test data, and the part that resolves each item.
Based on 246 MOT tests in DVSA data.
About 6.5% of MOT tests recorded on the BMW M240i in DVSA data end in a failure. The same handful of items account for most of them.
Its most common failure is tyres, which makes up 37.5% of the BMW M240i's failures, followed by tyres, brakes. Each item below links to the part that resolves it. Confirm the exact fitment against your registration or VIN before buying, and have safety-critical work done by a competent mechanic.
What it fails on, and why
Tyres fail for tread below the 1.6mm legal limit across the central three-quarters, uneven or exposed-cord wear, or sidewall damage. The tester inspects all four; a single illegal tyre is a fail.
Brake failures cover worn pads and discs, an imbalance between wheels, corroded or scored discs, or a binding caliper. Braking efficiency is measured on a rolling road, so a spongy or pulling brake shows up as a low reading.
The parts that fix each
If your car has just failed, you have 10 working days to fix the items and get a free partial retest. These are the usual parts; confirm the exact fitment against your registration or VIN before buying.
