Real UK data on which Jaguar models and engines generate the most replacement enquiries - the XF X260 and AJ200D / 204DTD lead the rankings in 2025.
Across 4,625 real UK Jaguar engine enquiries in 2025, the XF X260 is the most-enquired model with 276 requests, closely followed by the XE X760 at 260. In the engine ranking, the AJ200D / 204DTD leads with 590 enquiries, ahead of the AJ126 3.0 V6 SC at 560.
Full methodology, complete ranking tables and what this means for owners below.
How we determine the most enquired models and engines.
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 we cover; 4,625 of these relate specifically to Jaguar 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. For models, we aggregate by chassis code (e.g., X260 for XF).
What this data cannot tell you: enquiry volume reflects market demand, not failure rates. A high number may indicate a large vehicle parc, an ageing fleet, or a model with known issues. We always pair enquiry data with known failure patterns and cost data for context.
Refresh cycle: annually, each February, covering the prior full calendar year. This is the first edition; future reports will show year‑on‑year changes.

Dominance of the Ingenium family: The AJ200D (diesel) and AJ200P (petrol) collectively account for over 1,000 enquiries, reflecting their widespread fitment across the modern Jaguar range. Both are also the subject of well‑documented timing chain and cooling system issues, which drive replacement demand [PATTERN DATA].
XF and XE lead the model rankings: The XF X260 and XE X760 are the two most popular models, consistent with their high sales volumes and the fact that they share the Ingenium powertrains. The older XF X250 still generates significant enquiries (178), driven by the AJ126 V6 and 276DT engines [PATTERN DATA].
High‑performance and older models: The AJ133 V8 and the XJ X351 appear in the top five, indicating that even premium models are not immune to replacement needs. The X‑Type and S‑Type, though older, still generate notable enquiry volumes, often from owners facing the 60% scrap threshold decision [PATTERN DATA].
What this doesn't show: Enquiry volume is not a failure rate. It should be read alongside mileage‑at‑failure data and known failure patterns to assess risk. For example, the high AJ200D volume reflects both its popularity and its known issues - but it also has a large vehicle parc.
If you own one of the most‑enquired models or engines, it doesn't mean your car is guaranteed to fail - but it does mean that replacement parts and specialist knowledge are widely available. For example, the AJ200D is the most common engine we see, so there is a competitive reconditioned market and many specialists familiar with its weaknesses.
Use our Repair vs Replace Calculator to assess your specific vehicle's financial risk. Also, check your engine's Knowledge Centre for tailored failure patterns and preventative actions.
We'll update these rankings annually - watch for shifts that may indicate changing reliability or model popularity.

The XF X260 leads with 276 enquiries in 2025, closely followed by the XE X760 at 260. Both are modern executive models with high sales volumes and Ingenium engines.
The AJ200D / 204DTD (Ingenium diesel) is the most‑enquired engine with 590 requests, reflecting its widespread use across XE, XF, F‑Pace and E‑Pace, as well as known timing chain and oil dilution issues.
Not necessarily. High enquiry volume often reflects a large vehicle parc or an ageing fleet. For example, the XF X260 is popular, so its absolute enquiry number is high. Always check failure pattern data for the specific engine.
