The headline findings from our 2025 UK enquiry data.
Our data covers 24,650 total UK engine enquiries in 2025 across all brands [EM-VERIFIED], of which 9,000+ are Land Rover‑specific. The 204DTD (2.0 Ingenium diesel) is the most‑enquired Land Rover engine, with 1,150 enquiries, followed closely by the 306DT (3.0 TDV6/SDV6) at 980 enquiries [EM-VERIFIED].
High enquiry volumes do not necessarily mean high failure rates — they reflect vehicle population, age, and typical replacement mileage. For a proper risk assessment, we combine enquiry data with [PATTERN DATA] from workshop notes and manufacturer TSBs, and with [EM-QUOTE] cost data from actual supplier quotes.
Key findings include:
- The 306DT crankshaft bearing failure is the single most catastrophic and expensive failure mode in our dataset, with recon costs of £6,500–£9,500 [EM-QUOTE].
- Ingenium diesels (204DTD/AJ20D6) show timing chain tensioner wear, particularly on pre‑2019 units, with repair costs of £1,200–£2,500 for the chain alone [EM-QUOTE].
- The 276DT (2.7 TDV6) oil pump failure is a well‑documented risk, with repair costs of £1,500–£3,000 and, if ignored, full engine replacement at £5,000–£7,500 [EM-QUOTE].
- The 448DT (4.4 SDV8) is considered the most durable of the modern Land Rover diesels, with no catastrophic design flaw and a high repairability index [PATTERN DATA].
