1988 Mercedes-Benz 190 E — MOT failures & pass rate
488 MOT tests on the 1988 Mercedes-Benz 190 E are in this dataset, and 77.9% of them passed. All cars of a similar age fail 20.9% of the time, so this is 1.2pp worse than the group it competes with. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (11.3%) and brakes (9.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, non catalyst emissions and integral vehicle structure condition — headlamp aim alone was recorded 30 times.
A 150k+ example is materially riskier than a 30-60k one: 25.6% versus 6.8%.
Suspension is the most common advisory, noted on 27.3% of tests — work that passed today but is likely due soon.
The trend is worsening — 20.3% of tests failed in 2021 against 22.8% 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 | 27.3% | 133 |
| 2 | Brakes | 24.0% | 117 |
| 3 | Body, structure & corrosion | 15.4% | 75 |
| 4 | Emissions & environmental | 13.3% | 65 |
| 5 | Tyres | 11.3% | 55 |
| 6 | Other defects | 9.6% | 47 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 44 | 6.8% |
| 60-90k | 98 | 23.5% |
| 90-120k | 130 | 20.0% |
| 120-150k | 123 | 27.6% |
| 150k+ | 82 | 25.6% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 113 | 20.3% |
| 2022 | 108 | 24.1% |
| 2023 | 93 | 24.7% |
| 2024 | 82 | 18.3% |

What to check before buying a 1988 190 E
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 11.3% of tests. Start there.
- Lighting & signalling (11.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (9.0% 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.
- Body, structure & corrosion (8.8% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
