BMW Ix1 Xdrive common MOT failures and failure rate
What a BMW Ix1 Xdrive fails its MOT on, from real DVSA test data, and the part that resolves each item.
Based on 1,840 MOT tests in DVSA data.
About 12.5% of MOT tests recorded on the BMW Ix1 Xdrive 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 82.2% of the BMW Ix1 Xdrive's failures, followed by tyres, visibility/wipers, other, 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.
Visibility failures include torn or smearing wiper blades, a washer jet that does not reach the screen, and chips or cracks in the driver's swept area. Blades and washer fluid are quick, cheap fixes.
This covers a range of smaller items, from a non-working horn to a warning light left on.
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.
Seat-belt failures are frays, cuts, corroded anchorages, or a belt that will not lock under a sharp pull or retract properly.
A missing, damaged, dirty or incorrectly-spaced number plate, or one using the wrong font, will fail. A replacement plate is inexpensive.
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.
