Citroën V56.12 ECU Replacement | 1.2 PureTech Replacement ECU
Has your Citroën been diagnosed with a faulty V56.12 Engine Control Unit (ECU)? Pelican Diagnostics supplies professionally programmed replacement ECUs for selected Citroën 1.2 PureTech non-turbo vehicles fitted with Continental and Vitesco V56.12 engine management systems.
Our Citroën V56.12 ECU Replacement provides a cost-effective alternative to expensive dealership replacement units. Using professional programming equipment, we disable the immobiliser in a compatible replacement unit, ensuring it is correctly prepared for your vehicle.
Whether your original ECU has suffered an internal hardware failure, processor fault, communication issue or has simply failed to operate correctly, our replacement ECU solution is designed to get your vehicle back on the road quickly and reliably.
Please compare your ECU part number with the supported numbers listed below before ordering. If you’re unsure, simply contact us and we’ll be happy to confirm compatibility.
Immobiliser delete in the engine ECU does not affect your vehicle’s security as an original programmed key will still be required to start the vehicle. The immo delete only allows an un-programmed ECU to be fitted to the car, thereby avoiding expensive dealer replacement, programming and extended waiting times.

What’s Included?

The replacement unit is supplied prepared for installation into the vehicle. Diagnostic fault codes may still need to be cleared after fitting, and vehicle-specific adaptations may be required in some cases.
