Diesel against the other Volkswagen Tiguan versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 81.8% | 158,261 |
| Petrol | 88.3% | 27,640 |
| All Volkswagen Tiguan | 82.8% | 185,902 |
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 Volkswagen Tiguan specifically, petrol is the strongest at 88.3%, and this diesel version sits 1 points below the 82.8% model average.
What it means if you are buying one
The diesel Volkswagen Tiguan 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. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Volkswagen Tiguan had covered 78,558 miles at test, against 46,401 for the petrol. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.
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 Volkswagen Tiguan page separate age from fuel if you want to isolate one.
