The Discovery Sport and the 204DTD Ingenium diesel top our 2025 enquiry rankings — 4,935 real UK replacement requests reveal which vehicles and powertrains generate the most demand, and what that means for owners.
In 2025, the Discovery Sport (362 enquiries) and Evoque L551 (349) led all Land Rover models, while the 204DTD Ingenium diesel (1,150 enquiries) was the most-enquired engine — together reflecting the popularity of the modern Ingenium-powered SUV range.
Full methodology, rankings and what this means for your own vehicle below.
How we built this ranking from real UK enquiry data.
Source: Internal CRM quote-request data from EnginesMarket.co.uk and EngineFinders.co.uk, combined. Full calendar year 2025. 24,650 unique quote requests across all brands; 4,935 of these relate specifically to Land Rover and Range Rover engines.
What counts as an "enquiry": a unique customer quote request specifying a particular engine code or vehicle. Repeat requests from the same customer for the same engine are not double-counted.
What this data cannot tell you: our dataset reflects people who contacted us about a replacement engine — it is not a random sample of every Land Rover on UK roads. A higher enquiry count can mean an engine or model is more failure-prone, or simply that more of that vehicle exist in the parc, or that it's an older vehicle reaching typical replacement age. We do not claim failure rates against the total vehicle population; only enquiry share within our own dataset.
Refresh cycle: annually, each February, covering the prior full calendar year. Figures are locked at time of publication and are not silently revised — any correction is logged on our public corrections page rather than edited away.
The 204DTD leads by a significant margin, followed by the 306DT V6 diesel.

The overlap between the most-enquired engines and models is striking. The 204DTD appears in the Discovery Sport, Evoque (both generations), Velar, and Defender – all high-volume modern Land Rover models. The 306DT powers the Range Rover and Range Rover Sport, which also feature high up the model ranking. This suggests that the enquiry volume is driven as much by the sheer number of these vehicles on UK roads as by any specific failure propensity. However, the presence of older models like the L538 Evoque and L320 Sport (with the 276DT and 368DT) indicates that age and mileage also play a role.
It's also worth noting that the 204DTD (Ingenium diesel) is the most-enquired engine across all brands in our full 2025 dataset (1,150), outstripping even the BMW N47 (1,450) when you consider that the N47 also appears in many non-Land Rover models. This underscores the significance of Land Rover's Ingenium diesel in the UK replacement market.
If you own a Discovery Sport, Evoque, or Range Rover Sport, you're driving one of the most common vehicles we see in our enquiry data. That doesn't mean your car is destined to fail – it means that if you do need a replacement engine, there is a well-established supply chain and a network of specialists familiar with these models. The 204DTD, for example, is widely available in reconditioned form, and many independent specialists have deep experience with its timing chain and oil dilution issues.
For older models like the L538 Evoque and L320 Sport, the repair-or-replace decision is more nuanced. The 224DT (Ford-sourced) is cheaper to replace, but the 276DT and 368DT come with higher costs and known failure modes – see our 276DT oil pump failure and 368DT turbo/injector pages for detailed guidance.
