Electrical gremlins are the faults that frustrate owners most: a battery that is flat after a weekend, a window that works only sometimes, a tailgate that opens on its own. Range Rovers have complex power management with dual batteries on many models, and small faults can cascade into a dashboard full of warnings.
Our electrical technicians use oscilloscopes, current clamps and factory wiring diagrams to find the real cause. We repair harnesses to OEM standards rather than replacing entire looms, and we correctly register new batteries with the vehicle so the charging strategy is reset.
Electrical & Wiring Repair on the Range Rover Sport
The Range Rover Sport is driven harder than any other Land Rover, and it shows. Supercharger bearings, brake wear and air suspension on the SVR and V8 models are our daily work, alongside the diesel V6 family's timing chains.
Engines we cover on this model: 3.0 TDV6/SDV6, 5.0 V8 Supercharged, 3.0 Ingenium P400, SVR 5.0. Production 2005 – present (L320, L494, L461). Faults we see most often on the Range Rover Sport include supercharger nose bearing whine on 5.0 v8, front air strut and valve block leaks, brake disc warping under hard use, and each is diagnosed with the model-specific procedure before any parts are recommended.

How we work
Every job begins with a proper diagnosis on the lift and on Land Rover's diagnostic platform. You receive a written report, photos and a fixed price on WhatsApp before any work begins. Genuine or OE-equivalent parts are used, every repair carries a written warranty, and the vehicle is road tested before handover.
Frequently asked questions
Why does my Range Rover battery keep going flat?
Usually a module that fails to go to sleep, keeping the network awake. We measure the drain over time and isolate the circuit responsible.
Do you need to register a new battery?
Yes. Without registration the vehicle continues to charge as if the old, tired battery is fitted, shortening the life of the new one.
Can you repair a damaged wiring loom?
In almost every case. We use OEM-grade wire, terminals and heat-shrink to restore the loom to factory standard.
