Tmec 125 MOT failure rate
What a Tmec 125 fails its MOT on, from real DVSA test data, and the part that resolves each item.
Based on 55 MOT tests in DVSA data.
We hold 55 MOT tests for the Tmec 125 in the DVSA data. That is a smaller sample than our high-volume models, so treat these figures as indicative rather than definitive.
On what we have, about 45.5% fail, most often on lamps & electrical, other, brakes, suspension. For a precise picture of your own car, use the registration check on the home page. Confirm any part against your registration or VIN before buying.
What it fails on, and why
Lighting is the single most common MOT failure and the cheapest to put right. A blown headlight, brake-light or number-plate bulb, a cracked lens, or a headlamp beam that points too high or low will all fail. Most are a two-minute bulb swap.
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.
Suspension failures usually mean a worn or snapped coil spring, a leaking shock absorber, or play in a lower arm ball joint or bush. The tester checks for corrosion, fractures and excessive movement. A broken front spring is one of the most common failures on higher-mileage cars and is a straightforward replacement.
Steering faults are typically worn track-rod ends or ball joints, play in the rack, or a split gaiter letting grease out and dirt in. Excessive free play at the wheel fails.
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.
