Discovery 4 (Mk4) New Engine Control Module (ECM/PCM) Programming Service in London
If your **Land Rover Discovery 4 (2010-2016 Diesel)** requires a new or used **Engine Control Module (ECM) or Powertrain Control Module (PCM)**, it must be electronically programmed and configured to communicate with the vehicle's Immobiliser (PATS) and Body Control Modules (BCM). Simply swapping the unit will result in a **non-start condition**. Our **mobile JLR specialist** service covers **London**, equipped with the necessary diagnostic tools (**JLR SDD/Pathfinder**) to perform **security access, module synchronization, software flashing, and calibration** right at your location, saving you expensive recovery fees and dealer time.
