JLR BCM Module DX23-14B476-AG Virginized EEPROM

Product Overview

The JLR BCM Module DX23-14B476-AG Virginized EEPROM offers a professional-grade repair route for failing body control modules. When the original BCM fails, your vehicle suffers lighting faults, non-start issues, or erratic wiper and locking behaviour. Installing a used module without virginization creates a dead end because the VIN and immobilizer data stored in the chip block any reprogramming attempt. Our team takes each DX23-14B476-AG, erases the entire EEPROM to factory blank condition, and bench-tests every function. You then enjoy a hassle-free programming session using standard JLR diagnostic tools.

Why a Blank EEPROM Matters

Jaguar Land Rover embeds security access codes and vehicle configuration directly inside the BCM memory. A used module carries its previous vehicle identity permanently unless you overwrite it at binary level. Even skilled specialists find manual EEPROM editing time-consuming and error-prone. Our virginization process completely resets the chip, returning it to the exact state it leaves the factory. The JLR diagnostic software detects this blank module, prompts you for the correct VIN, and automatically writes all required As-Built data. This method eliminates checksum risks, configuration conflicts, and the need for external programmers.

Technical Specifications

• Part Number: DX23-14B476-AG (verify label; also compatible with AF, AH suffixes on some models)
• Memory: Serial EEPROM, full sector erase and byte-level verification
• Network Support: High and low-speed CAN bus, LIN bus for peripheral controls
• Pretest: Live bench test—power rails, CAN response, all input/output channels exercised
• Packaging: Anti-static sealed bag with protective foam and security seal

Vehicle Compatibility

This module fits many Jaguar Land Rover models, typically from 2014 to 2019. Always match the part number on your original unit. Common applications include:

• Range Rover Sport (L494) 2014 – 2017
• Range Rover (L405) 2013 – 2017
• Land Rover Discovery 5 (L462) 2017 – 2019
• Range Rover Velar (L560) 2017 – 2019
• Jaguar F-Pace (X761) 2016 – 2019
• Jaguar XE (X760) 2015 – 2019
• Jaguar XF (X260) 2015 – 2019

If your vehicle falls outside these ranges or carries a slightly different suffix, contact us with your VIN—we provide exact compatibility confirmation within hours.

Step-by-Step Programming Guide

1. Remove the faulty BCM and install the virginized DX23-14B476-AG in its place.
2. Connect a recommended JLR diagnostic interface (Mongoose Pro, VXDIAG, or genuine dealer VCI).
3. Launch the appropriate software (JLR SDD or Pathfinder, depending on model year).
4. Run a network test to confirm ECU communication.
5. Select the “Module Replacement” or “PMI” routine for the BCM.
6. The system detects the blank memory and guides you through VIN entry and data download.
7. After programming, synchronise keys and clear all fault codes.
8. Test lights, wipers, locks, and start the vehicle.

Most users complete the job within 30 minutes. No special hardware—just your regular diagnostics kit.

We dispatch same-day from the UK with full tracking and deliver to workshops and individuals worldwide.

Frequently Asked Questions

Q: Does this module require any extra hardware for programming?
A: Only the diagnostic tool you normally use for JLR vehicles. You do not need an EEPROM programmer or soldering equipment.

Q: Can I use this BCM if my original part number ends in AF instead of AG?
A: In most cases, yes—the hardware is identical. However, we always recommend matching suffixes. Contact us with both part numbers and we will confirm quickly.

Q: What if I encounter a programming failure?
A: Our technical team provides remote support. We have documented fixes for common software hiccups. If the module proves faulty, we replace it under our 12-month warranty.
