Discovery 3 & Range Rover Sport (Early) CJB Repair / Clone / Cloning service

The "Plug & Play" Solution for Water-Damaged Fuse Boxes

The Central Junction Box (CJB) in the Discovery 3 and early Range Rover Sport is the "brain" of your vehicle's electronics. Due to their location behind the glovebox, these units are notorious for terminal corrosion caused by leaking sunroof drains or A-pillar seals. Moisture enters the multi-layered PCB, causing "ghost" electrical faults that are impossible to fix with a simple fuse change.

Common Symptoms of Failure:

• Wiper Malfunctions: Front or rear wipers staying on permanently (even with ignition off) or not working at all.
• Central Locking Issues: Doors cycling (machine-gunning) or failing to unlock/lock via the remote.
• Lighting Faults: Interior lights flickering or staying on; indicators behaving erratically.
• Battery Drain: High parasitic draw often caused by shorted internal relays.

Why Cloning is the Preferred Choice: A brand-new replacement from a dealer requires a "virgin" setup and expensive online programming. Our Cloning Service allows you to source a cost-effective, used donor unit from eBay or a breaker. We perform a bit-for-bit data migration of your vehicle’s "Identity"—including the VIN, Key Transponder data, and Car Configuration Files (CCF)—directly onto the donor hardware.
