Diesel against the other Ford Focus C-Max versions
| Fuel | Pass rate | Tests |
|---|---|---|

| Diesel | 58.5% | 3,926 |
| All Ford Focus C-Max | 60.1% | 14,247 |
Why the fuel type changes the number
Diesels carry DPFs, EGR valves and stricter smoke limits, so emissions and exhaust faults account for failures petrol cars never see.
On the Ford Focus C-Max specifically, petrol is the strongest at 60.7%, and this diesel version sits 1.6 points below the 60.1% model average.
What it means if you are buying one
The diesel Ford Focus C-Max fails more often than the model average, so budget for the items that catch this fuel type and treat a fresh MOT as worth paying for. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Ford Focus C-Max had covered 123,002 miles at test, against 104,149 for the petrol. That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself.
Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Ford Focus C-Max page separate age from fuel if you want to isolate one.
