1993 Mercedes-Benz 190 E — MOT failures & pass rate
The 1993 Mercedes-Benz 190 E passed 79.2% of its 2,403 recorded MOT tests. That is 2.6 percentage points better than all cars of a similar age, which fail at 23.4%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (11.1%) and suspension (8.2%) 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, catalyst emissions and headlamp aim — component mounting prescribed areas alone was recorded 132 times.
Condition tracks the odometer closely. Failures run at 14.0% in the 30-60k band and 26.4% in the 150k+ band, a 12.5-point spread.
Brakes is the most common advisory, noted on 31.9% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 21.2% in 2021 to 19.7% 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 |

| 120-150k | 628 | 21.8% |
| 150k+ | 579 | 26.4% |
Trend over time

What to check before buying a 1993 190 E
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 11.1% of tests. Start there.
- Lighting & signalling (11.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (8.2% 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.
- Brakes (7.6% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
