Diesel SEAT Toledo: MOT pass rate

70.5% of diesel SEAT Toledos pass the MOT first time, measured across 2,916 DVSA tests on that fuel type alone. Average mileage at test was 148,136.

Diesel against the other SEAT Toledo 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 SEAT Toledo specifically, petrol is the strongest at 78.1%, and this diesel version sits 3.9 points below the 74.4% model average.

What it means if you are buying one

The diesel SEAT Toledo 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 SEAT Toledo had covered 148,136 miles at test, against 66,262 for the petrol. That is very high mileage. Clutches, dual-mass flywheels and head gaskets have usually been through at least one repair by this point, so ask for evidence rather than assume the car is original everywhere.

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