1989 Mercedes-Benz 190 E — MOT failures & pass rate
The 1989 Mercedes-Benz 190 E passed 80.7% of its 1,402 recorded MOT tests. That is 2.1 percentage points better than all cars of a similar age, which fail at 21.3%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (9.9%) and brakes (8.1%) 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 service brake performance — component mounting prescribed areas alone was recorded 66 times.
A 150k+ example is materially riskier than a 0-30k one: 20.8% versus 11.3%.
Advisories point at the next bill rather than this one: suspension was flagged on 26.3% of tests without failing them.

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 | 26.3% | 368 |
| 2 | Brakes | 25.6% | 359 |
| 3 | Body, structure & corrosion | 17.7% | 248 |
| 4 | Tyres | 15.0% | 211 |
| 5 | Emissions & environmental | 15.0% | 211 |
| 6 | Other defects | 8.8% | 124 |
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 | 53 | 11.3% |
| 30-60k | 130 | 20.8% |
| 60-90k | 209 | 19.6% |
| 90-120k | 305 | 16.4% |
| 120-150k | 340 | 20.6% |
| 150k+ | 365 | 20.8% |
Trend over time

What to check before buying a 1989 190 E
On a 1989 190 E, lighting & signalling is what the MOT record says goes wrong most — it appeared in 9.9% of tests. Check these areas before you commit.
- Lighting & signalling (9.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.1% 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 (7.9% 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.
