2007 Mercedes-Benz Motorhome — MOT failures & pass rate
Across 280 MOT tests, the 2007 Mercedes-Benz Motorhome recorded an 87.1% pass rate. All cars of a similar age fail 26.9% of the time, so this is 14.0pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (6.1%) and brakes (4.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are brake discs, wipers and exhaust system — brake discs alone was recorded 8 times.
Advisories point at the next bill rather than this one: brakes was flagged on 16.4% 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 | Brakes | 16.4% | 46 |
| 2 | Suspension | 12.5% | 35 |
| 3 | Lighting & signalling | 12.1% | 34 |

| 5 | Visibility | 3.9% | 11 |
| 6 | Other defects | 3.2% | 9 |
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 | 150 | 12.7% |
| 60-90k | 72 | 15.3% |
Failure rate by age
Trend over time

What to check before buying a 2007 Motorhome
On a 2007 Motorhome, lighting & signalling is what the MOT record says goes wrong most — it appeared in 6.1% of tests. Check these areas before you commit.
- Lighting & signalling (6.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (4.6% 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.
- Visibility (4.3% 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.
