⚡ Range Rover Sport Dashboard Warning Lights
The encyclopedia – 50+ warning lights, professional diagnosis, real repair costs, and emergency procedures. Developed by Land Rover master technicians.
⚠️ Check Engine / Malfunction Indicator Light
Most CommonIssue
Emission system fault, engine misfire, oxygen sensor, MAF sensor, catalytic converter, or EVAP leak. Range Rover V6/V8 engines are sensitive to fuel quality and ignition coils.
🧾 Symptoms
- 🚨 Solid amber engine light – fault detected
- ⚡ Flashing light – severe misfire (stop driving)
- 📉 Reduced power / limp mode
- ⛽ Poor fuel economy, rough idle
🔬 PROFESSIONAL DIAGNOSIS (5+ methods)
OBD-II Scan
Read codes with advanced scanner (Autel, Foxwell). Record freeze frame data.
Live Data
Monitor STFT/LTFT, O2 sensor voltage, MAF g/s, ignition timing.
Smoke Test
Pressurize EVAP/intake system to locate vacuum leaks (common on supercharged engines).
Coil & Plug Test
Swap ignition coils, inspect spark plugs for carbon fouling (5.0L V8 known for coil failures).
Fuel Pressure Test
Check low-pressure pump and high-pressure pump on GDI engines.
Compression & Leak-down
Mechanical health – timing chain stretch? (P0016/P0018).

🛑 ABS / Traction Control / DSC
Safety criticalWarning lights: ABS, BRAKE, DSC OFF, or “STABILITY CONTROL FAULT”.
🔧 Issue
- Wheel speed sensor failure (front most common)
- ABS module internal failure (Land Rover frequent issue)
- Tone ring cracked / rusted (rear)
- Low brake fluid or brake switch
📋 Symptoms
- Amber ABS light + DSC amber light
- Pulsating brake pedal when stopping
- No ABS activation during hard brake
- Hill Descent Control unavailable
📌 Multi‑option Diagnosis
- Scan ABS module – retrieve Cxxxx codes (C0035, C0040, C1A00).
- Inspect wheel speed sensors: measure resistance (1.1–1.8 kΩ), AC voltage while spinning wheel.
- Oscilloscope test: square wave pattern clean? (intermittent failure).
- Check ABS module power/ground – many Range Rovers need module rebuild.
- Inspect reluctor rings – corrosion causes air gap issues.
