Diesel against the other Renault Megane Scenic 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 Renault Megane Scenic specifically, diesel is the strongest at 73.2%, and this diesel version sits 6.6 points above the 66.6% model average.

What it means if you are buying one

The diesel Renault Megane Scenic is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. 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 Renault Megane Scenic had covered 84,443 miles at test, against 102,377 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 Renault Megane Scenic page separate age from fuel if you want to isolate one.
