The 276DT (2.7‑litre TDV6) is a shared engine with Land Rover, generating 700 UK enquiries in 2025. This page examines its failure patterns, typical mileage, and cost data for Jaguar applications.
The 276DT is a 2.7‑litre V6 diesel used across the Jaguar XF, XJ and X‑Type, as well as many Land Rovers. In our 2025 data, it generated 700 combined enquiries across both brands, with Jaguar‑specific models accounting for a significant share. Typical failures occur between 80,000 and 140,000 miles, with oil pump failure being the most common catastrophic issue. Reconditioned supply costs range from £5,000 to £7,500, but lower typical host values mean the repair‑to‑value calculation is more critical.
Full breakdown below - including how the 276DT compares to other Jaguar engines, and what you can do to avoid a costly failure.
How the 276DT compares to other Jaguar engines in real enquiry data.
The 276DT (also known as the 2.7‑litre TDV6) is a Ford‑derived V6 diesel that was extensively used by Jaguar Land Rover. In our 2025 data, it generated 700 unique quote requests across both Land Rover and Jaguar models [EM-VERIFIED]. That makes it the eleventh most‑enquired engine in our entire dataset.
For Jaguar specifically, the 276DT is fitted to the XF (X250), XJ (X350, X358) and X‑Type (X400) - all models that appear in our model enquiry list. While the total 700 figure includes Land Rover applications, we can infer a significant Jaguar share from model‑level data:
| Jaguar Model | 2025 Enquiries (all engines) | Typical 276DT Fitment |
|---|---|---|
| XF X250 | 178 [EM‑VERIFIED] | 2.7D |
| XJ X350 / X358 | 120 [EM‑VERIFIED] | 2.7D |
| X‑Type X400 | 120 [EM‑VERIFIED] | 2.0D, 2.2D (not 276DT) |

As always, enquiry volume is not the same as failure rate. The 276DT's count reflects its widespread use across both brands and its age profile - many examples are now entering the typical failure mileage band. However, the pattern of failures reported by specialists confirms that the engine does have a genuine weak point: the oil pump housing.

At what mileage do 276DT owners typically report problems?
Based on our [PATTERN DATA] from specialist interviews and owner surveys, the 276DT shows a clear mileage‑related pattern. The majority of enquiries and reported failures fall into three bands:
Importantly, the 276DT's oil pump failure is often sudden and without extensive prior warning - unlike timing chain issues that give a rattling noise for weeks. This makes regular oil pressure testing and early diagnosis critical. Many specialists recommend an oil pump inspection at 80k miles to catch any degradation.

Ranked by cost and severity - from the most common to the most expensive.
| Rank | Failure Mode | Typical Mileage | Repair Cost (Indie) | Severity |
|---|---|---|---|---|
| 1 | Oil pump housing failure | 80k–140k | Oil pump: £1,500–£3,000 Full recon: £5,000–£7,500 |
Catastrophic |
| 2 | Turbocharger failure | 90k–150k | £1,200–£2,500 | Immediate |
| 3 | EGR valve / cooler issues | 80k–120k | £500–£1,200 | Monitor |
All cost ranges [EM-QUOTE] based on supplier quotes and specialist interviews. Severity scale: Catastrophic / Immediate / Monitor.
The oil pump housing failure is the most critical and costly. It is caused by a weak point in the pump housing at the tensioner mount, which can fail and cause a loss of oil pressure. A cold‑start knock is the classic early warning - ignoring it can lead to a seized engine and a full replacement. Our full oil pump failure guide explains the diagnosis and repair process in detail.
Turbocharger failure and EGR issues are less catastrophic but still expensive. Regular servicing with the correct oil specification and avoiding excessive idling can help extend turbo life.
Real‑world lifespan of the 276DT - and what makes the difference.
With proper maintenance, the 276DT is capable of 150,000–200,000 miles of reliable service [EM-INTERVIEW]. Many examples on UK roads have exceeded this, particularly those in Jaguar saloons that are predominantly motorway‑driven.
The key to longevity is oil changes at 5,000–6,000 mile intervals (significantly shorter than the manufacturer's extended schedule), using a high‑quality oil that meets JLR spec. Frequent short trips and towing heavy loads (more common in Land Rover applications) increase oil pump stress, so Jaguar owners may have a slight advantage here.
Early detection of oil pump wear is crucial. Specialists recommend an oil pressure test at 80k miles to check for any degradation in the pump housing. A simple sump inspection can also reveal the condition of the oil pump and tensioner.

A balanced assessment of the 276DT's reliability and value.
Reliability rating: 2.5 / 5 (provisional)
The 276DT is a torquey V6 diesel that delivers strong performance in the XF and XJ. However, its reputation is seriously damaged by the oil pump housing failure, which can be sudden and expensive. With proactive maintenance - particularly shortened oil change intervals and early oil pressure testing - it can still provide a long, trouble‑free life, but owners must be vigilant.
Our advice: If you're buying used, prioritise a car with a documented service history and evidence of regular oil changes. Consider having an oil pressure test performed as part of the pre‑purchase inspection. If you already own a 276DT, budget for an oil pump inspection at 80k miles and be alert to any cold‑start knocking.

The 276DT is a 2.7‑litre V6 diesel engine, also known as the TDV6. It appears in the Jaguar XF (X250), XJ (X350, X358), and previously in the X‑Type. It is also widely used in Land Rovers such as the Discovery 3 and Range Rover Sport.
It has a reputation for oil pump housing failure, which is a well‑known weak point. With diligent maintenance - especially frequent oil changes and early oil pressure testing - many examples exceed 150,000 miles. However, the failure risk is real and can be sudden.
The most common early warning is a knocking or rattling noise from the engine on cold start, which may fade as the engine warms up. As wear progresses, the knock becomes louder and more persistent, and oil pressure may drop. Catastrophic failure can occur without much warning.
A reconditioned engine supply costs £5,000–£7,500, with fitting labour adding £910–£1,170 at independent rates. Main dealer costs are significantly higher. An oil pump replacement may be cheaper if caught early, but full replacement is often the only option once the pump fails catastrophically.
With proper care, many 276DT engines exceed 150,000 miles. However, the oil pump failure risk increases after 80,000 miles, so proactive monitoring is essential. Some well‑maintained examples have reached 200,000 miles.
