Jaguar & Land Rover CPLA-12B684-YE ECM Clone — Mail-In
Replacing a failed CPLA-12B684-YE engine ECM? Mail in your original plus a matching donor and we clone it — VIN, immobilizer, and config carried over so it plugs in and runs.
Sending several modules? Add them all — one box, one return-shipping charge.

Engines
Earlier JLR engine ECUs — verify first
- Denso AJ33 — 2005–2009 Range Rover 4.4 AJ-V8
- 2003–2005 Range Rover HSE ECM (L322, pre-CPLA hardware)
- These are different ECU families, not CPLA — send the label and we confirm feasibility and price before you ship
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Original ECM failed / water-damaged and you have a donor to clone onto
- Replacing a dead engine computer without a dealer trip or tow
- Used/donor CPLA ECM that needs your VIN + immo data written to it
- Want a spare programmed identical to the original
Won't fix:
- No donor module to clone onto (we need both the original and a matching donor with the same part number)
- Emissions defeat, delete files, or emissions-bypass services (we do not offer this)
- Mechanical engine faults unrelated to the ECM
- The CEM / fuse-box body control module — see our JLR CEM / fuse-box BCM clone service
- Key programming, all-keys-lost, or KVM / RFA work — see our Range Rover / Jaguar key programming and KVM virginize services
- Pre-CPLA hardware quoted sight-unseen — Denso AJ33 and 2003–2005 Range Rover HSE ECMs are a different family and are confirmed off the label first
Original unreadable? We can often still recover it.
If your original ECM is damaged but partially readable, we can usually still pull the VIN + immobilizer data needed to clone onto a healthy donor. Include both modules and a note describing the failure. If the original is completely dead we will tell you before any work and refund if we cannot complete the clone. The same bench workflow covers the wider Bosch MED17 / MEDC17 gas family fitted to Jaguar and Land Rover roughly 2011–2021, not only the CPLA-12B684-YE part number — and we also quote earlier generations such as the Denso AJ33 on the 2005–2009 Range Rover 4.4 and the 2003–2005 Range Rover HSE ECM, which are genuinely different hardware and are verified case-by-case before you ship. Proof of ownership is required because this work carries the immobilizer relationship.
