2016 Dacia Logan — MOT failures & pass rate
The 2016 Dacia Logan passed 84.0% of its 16,603 recorded MOT tests. Against small family cars of a similar age (13.7% fail rate), the 2016 Logan comes out 2.3pp worse. Failures cluster in lighting & signalling, visibility and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 9.1% of tests against 5.5% for the next-worst category.
At component level the recurring items are headlamp aim, washers and tread depth — headlamp aim alone was recorded 990 times.
A 150k+ example is materially riskier than a 0-30k one: 24.0% versus 7.0%.
The petrol cars hold up better: 14.3% fail against 17.1% for diesel, a 2.8-point gap across 16,603 tests.
Tyres is the most common advisory, noted on 25.1% of tests — work that passed today but is likely due soon.
The trend is worsening — 12.5% of tests failed in 2021 against 19.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2016 Logan
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 9.1% of tests. Start there.
- Lighting & signalling (9.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (5.5% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Suspension (5.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
