2005 Toyota Dyna — MOT failures & pass rate
The 2005 Toyota Dyna passed 69.3% of its 502 recorded MOT tests. That is 3.1 percentage points worse than all cars of a similar age, which fail at 27.6%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 20.1% of all tests — 3.6 points clear of brakes, so it is the first thing to check.
At component level the recurring items are position lamp, service brake performance and prescribed areas — position lamp alone was recorded 52 times.
Condition tracks the odometer closely. Failures run at 24.6% in the 60-90k band and 34.4% in the 150k+ band, a 9.7-point spread.
Advisories point at the next bill rather than this one: suspension was flagged on 41.8% of tests without failing them.
The trend is worsening — 26.2% of tests failed in 2021 against 30.5% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 41.8% | 210 |
| 2 | Brakes | 30.1% | 151 |
| 3 | Body, structure & corrosion | 22.5% | 113 |
| 4 | Tyres | 22.1% | 111 |
| 5 | Lighting & signalling | 18.7% | 94 |
| 6 | Other defects | 16.3% | 82 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 69 | 24.6% |
| 90-120k | 137 | 32.9% |
| 120-150k | 97 | 30.9% |
| 150k+ | 163 | 34.4% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2005 Dyna
On a 2005 Dyna, lighting & signalling is what the MOT record says goes wrong most — it appeared in 20.1% of tests. Check these areas before you commit.
- Lighting & signalling (20.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (16.5% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Suspension (10.2% 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.
