Diesel Porsche Panamera: MOT pass rate

85.2% of diesel Porsche Panameras pass the MOT first time, measured across 2,183 DVSA tests on that fuel type alone. Average mileage at test was 83,026.

Diesel against the other Porsche Panamera 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 Porsche Panamera specifically, hybrid is the strongest at 90.9%, and this diesel version sits 3.6 points below the 88.8% model average.

What it means if you are buying one

The diesel Porsche Panamera 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 Porsche Panamera had covered 83,026 miles at test, against 54,419 for the petrol and 51,068 for the hybrid. 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 Porsche Panamera page separate age from fuel if you want to isolate one.
