1990 Mercedes-Benz 190 E — MOT failures & pass rate
The 1990 Mercedes-Benz 190 E passed 79.4% of its 2,400 recorded MOT tests. That is 1.2 percentage points better than all cars of a similar age, which fail at 21.8%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (10.6%) and suspension (8.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, headlamp aim and position lamp — component mounting prescribed areas alone was recorded 150 times.
A 150k+ example is materially riskier than a 0-30k one: 24.1% versus 12.9%.
Advisories point at the next bill rather than this one: brakes was flagged on 26.8% of tests without failing them.
The trend is improving — the fail rate fell from 22.2% in 2021 to 18.7% in 2025, as the worst-kept examples leave the fleet.

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 | 26.8% | 644 |
| 2 | Suspension | 26.4% | 634 |

| 5 | Tyres | 14.8% | 354 |
| 6 | Other defects | 11.0% | 263 |
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 | 62 | 12.9% |
| 30-60k | 125 | 14.4% |
| 60-90k | 377 | 13.8% |
| 90-120k | 613 | 20.2% |
| 120-150k | 557 | 23.5% |
| 150k+ | 663 | 24.1% |
Trend over time

What to check before buying a 1990 190 E
On a 1990 190 E, lighting & signalling is what the MOT record says goes wrong most — it appeared in 10.6% of tests. Check these areas before you commit.
- Lighting & signalling (10.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (8.6% 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.
- Brakes (7.5% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
