Diesel Suzuki Sx4: MOT pass rate

69.9% of diesel Suzuki Sx4s pass the MOT first time, measured across 5,440 DVSA tests on that fuel type alone. Average mileage at test was 87,110.

Diesel against the other Suzuki Sx4 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 Suzuki Sx4 specifically, petrol is the strongest at 76.2%, and this diesel version sits 5.4 points below the 75.3% model average.

What it means if you are buying one

The diesel Suzuki Sx4 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 Suzuki Sx4 had covered 87,110 miles at test, against 68,830 for the petrol. That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures.

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 Sx4 page separate age from fuel if you want to isolate one.
