75.4% of diesel Toyota Auris pass the MOT first time, measured across 13,819 DVSA tests on that fuel type alone. Average mileage at test was 105,763.

Diesel against the other Toyota Auris 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 Toyota Auris specifically, hybrid is the strongest at 85.3%, and this diesel version sits 5.5 points below the 80.9% model average.

What it means if you are buying one

The diesel Toyota Auris 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 Toyota Auris had covered 105,763 miles at test, against 81,490 for the petrol and 97,693 for the hybrid and 109,651 for the electric. 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 Toyota Auris page separate age from fuel if you want to isolate one.
