2020 Dacia Duster Twenty Tce 4X2 — MOT failures & pass rate
Across 2,073 MOT tests, the 2020 Dacia Duster Twenty Tce 4X2 recorded an 89.1% pass rate. That is 1.5 percentage points worse than all cars of a similar age, which fail at 9.4%. Failures cluster in lighting & signalling, visibility and tyres.
What the MOT record shows
Lighting & signalling dominates the failure mix at 9.2% of all tests — 4.9 points clear of visibility, so it is the first thing to check.
At component level the recurring items are headlamp aim, wipers and headlamp — headlamp aim alone was recorded 145 times.
Condition tracks the odometer closely. Failures run at 7.6% in the 0-30k band and 23.6% in the 60-90k band, a 16.0-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 30.4% of tests without failing them.
The trend is worsening — 9.0% of tests failed in 2023 against 14.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2020 Duster Twenty Tce 4X2
On a 2020 Duster Twenty Tce 4X2, lighting & signalling is what the MOT record says goes wrong most — it appeared in 9.2% of tests. Check these areas before you commit.
- Lighting & signalling (9.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (4.3% 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.
- Tyres (4.1% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
