Land Rover Warning Lights Guide

Land Rover dashboard warning light guide explaining common symbols, what they mean, and when to seek professional help for your Range Rover or Range Rover Sport.

Modern Land Rover vehicles have sophisticated onboard diagnostics that monitor every system. When a warning light appears on your dashboard, understanding what it means helps you decide whether to continue driving or call for help. At GSR Garage in Telford, we regularly diagnose warning light issues on all Land Rover models. The engine management light (often orange or amber) can indicate anything from a loose fuel cap to a serious engine fault. Common causes we see on Land Rover vehicles include air suspension compressor failure and AdBlue system faults on SD4 and TDV6 engines. If the light is steady, you can usually continue driving but should have the vehicle checked soon. If the light is flashing, stop driving immediately and seek professional assistance. The DPF warning light on diesel Land Rover models indicates the particulate filter needs regeneration. AdBlue system faults on SD4 and TDV6 engines is a common cause. Driving at motorway speeds for 20-30 minutes may clear it. If the light stays on, professional cleaning or replacement may be needed. The ABS warning light indicates a fault with the anti-lock braking system. coolant loss from hose and thermostat failures can trigger this light. While the brakes will still work, the ABS may not function in an emergency stop. The airbag warning light should be investigated immediately as it indicates the supplemental restraint system may not deploy in a collision. For Land Rover vehicles, the battery warning light could indicate rear differential failure on Range Rover Sport or alternator failure. The AdBlue warning light on diesel models means the system needs attention, and EGR valve problems on diesel models is a common cause. At our Telford workshop, we see Land Rover vehicles daily and understand the specific issues affecting local drivers.
