Our Verdict
This is a strongly recommended purchase for buyers seeking a luxury diesel SUV with a clean history. The Bentley Bentayga (KCZ19) has passed every MOT since first registration with no defects recorded, indicating careful ownership.
Given the spotless MOT history with passes in 2022 (34,530 miles), 2023 (40,915 miles), 2024 (57,342 miles), 2025 (61,777 miles) and 2026 (66,437 miles), focus your negotiation on service history rather than rectifying faults. Confirm the vehicle has full Bentley main-dealer or specialist servicing, as these engines require precise maintenance that independent garages may not provide. The lack of MOT defects suggests good care, but a pre-purchase inspection by a Bentley-trained technician is still wise given the vehicle's value and complexity.
As a 3,956cc diesel Bentayga, expect high but not extreme running costs for the class; fuel economy is better than the petrol equivalent, though still modest for a large SUV. Road tax will be in the higher bands due to the engine size and 2018 registration, and insurance will reflect the vehicle's luxury status and repair costs. Typical annual maintenance for a Bentley of this type is considerable, with specialist servicing and parts commanding premium prices.
The MOT history shows no failures and no recorded defects across all five tests, so there are no specific failure types from the data to investigate. However, on a 2018 diesel Bentayga you should still inspect the AdBlue system, diesel particulate filter, and air suspension for early wear not yet flagged by MOTs. Verify the black paintwork for stone chips and check the interior electronics function fully, as these are common luxury-SUV considerations not captured in MOT results.
The 2018 Bentley Bentayga diesel presented in black has covered 66,437 miles as of its most recent MOT in May 2026, which is reasonable for an eight-year-old luxury SUV. Every MOT from 2022 to 2026 was a pass with no defects noted, showing consistent maintenance and no advisory issues. As a 3,956cc diesel model first registered in May 2018, it offers a prestige driving experience with a reassuringly clean test record.
No aggregate MOT reliability data is available for the Bentley Bentayga, so assessment is limited to this vehicle's individual clean history.

AI Analysis
Historical fault & advisory patterns
Common Problems: BENTLEY BENTAYGA
Known issues reported by owners and MOT testers.
- Carbon Build-up (GDI Coking)(Moderate)
Direct injection leads to carbon deposits on intake valves, reducing performance and fuel economy.
- Fuel Leak Recall(Serious)
Early V8 models were subject to a recall for a potential fuel leak from the fuel line quick connector.
- Infotainment and Electrical Glitches(Moderate)
The Bentayga's complex electronics, including the infotainment touchscreen, parking sensors, and adaptive cruise control, are prone to software bugs and random reboots. Moisture ingress into wiring can cause cascading electrical failures.
