2012 Mercedes-Benz Sprinter — MOT failures & pass rate
7,274 MOT tests on the 2012 Mercedes-Benz Sprinter are in this dataset, and 78.3% of them passed. That is 4.1 percentage points better than vans of a similar age, which fail at 25.7%. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (13.6%) and lighting & signalling (11.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), rigid brake pipes and headlamp aim — rbt (sp) alone was recorded 545 times.
Condition tracks the odometer closely. Failures run at 11.4% in the 0-30k band and 23.4% in the 150k+ band, a 12.1-point spread — more than double.
Brakes is the most common advisory, noted on 32.3% of tests — work that passed today but is likely due soon.
The trend is worsening — 19.8% of tests failed in 2021 against 22.5% 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 | Brakes | 32.3% | 2,349 |
| 2 | Suspension | 21.4% | 1,557 |

| 5 | Lighting & signalling | 10.8% | 786 |
| 6 | Emissions & environmental | 9.4% | 684 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 484 | 11.4% |
| 30-60k | 776 | 14.2% |
| 60-90k | 904 | 20.0% |

| 120-150k | 1,193 | 25.7% |
| 150k+ | 2,648 | 23.4% |
Failure rate by age

What to check before buying a 2012 Sprinter
The failure pattern for this year is specific enough to inspect against: brakes accounted for 13.6% of tests. Start there.
- Brakes (13.6% 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.
- Lighting & signalling (11.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (4.6% 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.
