Diesel against the other Dacia Duster versions

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 Dacia Duster specifically, petrol is the strongest at 85.1%, and this diesel version sits 5.2 points below the 79.9% model average.

What it means if you are buying one

The diesel Dacia Duster 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. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average diesel Dacia Duster had covered 69,991 miles at test, against 37,617 for the petrol. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.

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 Dacia Duster page separate age from fuel if you want to isolate one.
