Engine code, known faults, real cost data, and a repair‑or‑replace verdict - with a route to a quote if you want one. From there, confirm the exact spec on our engine number location guide, or run the numbers through our repair vs replace calculator.
This is one of eight free tools on the site - see also our registration lookup and engine value checker for related lookups.
The engine code is your vehicle's confirmed primary engine - for badges known to span two different engines across their production run (like certain D300 and D200 vehicles, covered in full on our AJ20D6 fitment guide), we'll flag this and point you to our engine number location guide to confirm. The verdict uses the same 60% repair‑to‑value framework published openly on our Decision Framework page - it's a starting guide based on typical values for your model, not a substitute for your own vehicle's specific valuation.
The year is derived from the 10th character of your VIN. The fuel type is determined by the engine code and model year. All data is drawn from our verified methodology.
If your VIN isn't recognised, you can use our full Fitment Matrix to identify your engine manually by model, generation and build year, or check the engine number stamp directly using our engine number location guide.
Fault and cost data behind this tool is drawn from the same 2025 UK enquiry dataset behind every other page on this site - full detail on our Data Methodology page. Build and fitment data is cross‑referenced against manufacturer records and independent parts suppliers. Our VIN decoding logic is informed by official Jaguar VIN structure documentation and cross‑checked with real‑world examples from our specialist network.
We also draw on the Engine Failure Index 2026 and failure‑rate‑by‑engine reports to provide context for known faults.
