Diesel against the other Suzuki Swift versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 77.3% | 112,708 |

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 Suzuki Swift specifically, hybrid is the strongest at 89.8%, and this diesel version sits 15 points below the 77.6% model average.
What it means if you are buying one
The diesel Suzuki Swift 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 Suzuki Swift had covered 98,283 miles at test, against 68,021 for the petrol and 39,280 for the hybrid. That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust.
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 Suzuki Swift page separate age from fuel if you want to isolate one.
