Service Overview
Our Electronic Modules Software Update service identifies outdated control unit software and loads the correct factory updates. We read the current module versions, compare them against the latest JLR release data, and program each module individually. The vehicle then operates with the same software level as a newly built vehicle from the production line.
You receive a complete factory-grade update service without any aftermarket software or unauthorised tuning. The programming uses the same JLR diagnostic platform that authorised workshops use for recall updates and technical service bulletins.
What the Service Includes
- Full diagnostic scan to identify all installed module software versions
- Comparison against the latest JLR approved software database
- Individual module reprogramming using factory diagnostic tools
- Battery support during programming to maintain stable voltage
- Post-update diagnostic verification and fault clearing
- Road test for dynamic systems where required
How the Electronic Modules Software Update Works
Modern Jaguar Land Rover vehicles contain multiple electronic control units linked by network buses. Each module stores calibration data that controls specific functions. Over time, JLR releases software updates that improve drivability, security, connectivity, and diagnostic accuracy. LR-Retrofit connects to the vehicle through the OBD port and loads these updates directly into each module.
The process maintains a stable power supply throughout, preventing voltage drop that could interrupt programming. Each module update completes individually with verification checks. The vehicle then communicates correctly across all systems, with improved response and reduced fault occurrence.
JLR Platform Compatibility
We supply Electronic Modules Software Updates for Range Rover, Range Rover Sport, Range Rover Velar, Range Rover Evoque, Discovery, Discovery Sport, Jaguar F-Pace, XF, XE and I-Pace. Most modern JLR vehicles with updatable control units qualify. Our team confirms your VIN and current software level before you book the service.
Programming and Calibration
LR-Retrofit technicians complete the software update at our workshop using JLR diagnostic equipment. We connect to the vehicle networks, identify outdated modules, and load the correct calibration files. After programming, we clear all stored faults and perform a full system scan to confirm successful communication. For engine or transmission updates, we also carry out a road test to verify correct operation.

Frequently Asked Questions
How do I know if my modules need a software update?
You may notice warning lights, glitches in infotainment, rough shifting, or communication faults. A diagnostic scan reveals outdated module versions. LR-Retrofit completes this scan and reports the findings before any update work.
Will the update affect my factory settings or retrofits?
No. LR-Retrofit preserves your existing vehicle configuration and retrofit coding. We update only the relevant modules and verify all settings after programming.
How long does the service take?
Most Electronic Modules Software Updates complete within two to four hours depending on module count. We schedule your vehicle in advance and provide a fixed quotation before any work begins.
