2024 Mercedes-Benz E-Class — MOT failures & pass rate
400 MOT tests on the 2024 Mercedes-Benz E-Class are in this dataset, and 97.5% of them passed. Executive cars of a similar age fail 4.4% of the time, so this is 1.9pp better than the group it competes with. Failures cluster in tyres, emissions & environmental and visibility.
What the MOT record shows
No single area dominates — tyres (2.3%) and emissions & environmental (0.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, washers and malfunction indicator lamp — tread depth alone was recorded 3 times.
Tyres is the most common advisory, noted on 8.5% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 8.5% | 34 |
| 2 | Other defects | 1.0% | 4 |
| 3 | Visibility | 0.8% | 3 |
| 4 | Brakes | 0.5% | 2 |
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 | 270 | 2.2% |
| 30-60k | 113 | 3.5% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Hybrid | 307 | 2.3% |
| Diesel | 87 | 2.3% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2024 | 34 | 5.9% |
| 2025 | 366 | 2.2% |
What to check before buying a 2024 E-Class
The failure pattern for this year is specific enough to inspect against: tyres accounted for 2.3% of tests. Start there.
- Tyres (2.3% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Emissions & environmental (0.3% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Visibility (0.3% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
