🔧 Plug-in Hybrid (P460e / P510e) – Fault Patterns We See
These Range Rover Sport PHEVs use powerful electric motors paired with a high-voltage battery and inverter system. But they’re not bulletproof.
Common Issues:
-
⚠️ Hybrid System Fault / Restricted Performance
-
🚫 Won’t enter READY mode / Electric motor offline
-
🔋 Battery won’t charge or rapid discharge
-
🔌 HV isolation fault / battery contactor error
-
🔥 Inverter thermal faults or water ingress
-
🧯 Hybrid safety interlock loop triggered
We diagnose and repair these issues with no need for dealer recovery.
⚙️ Mild Hybrid (MHEV – P400, D300) – Common Electrical Faults
MHEV models feature a 48V belt starter-generator (BiSG) and lithium battery that assists with start-stop and acceleration. Over time, faults build up.
Typical Faults:
-
🔋 48V battery charging fault
-
🛑 Start-stop permanently disabled
-
⚠️ Belt-integrated starter generator (BiSG) failure
-
🧠 Hybrid system unavailable / Electrical energy management DTCs
-
🔌 Voltage regulation or sensor feedback errors
Left unchecked, mild hybrid faults can affect overall vehicle performance and start reliability.
🛠️ How We Fix It – Fully Mobile Hybrid Diagnostics
✅ Land Rover-Level Diagnostics – We use genuine or dealer-equivalent tools to scan all hybrid ECUs and log live HV & 48V data.
✅ Visual + Electrical Checks – We check for damaged wiring, blown fuses, water ingress, and loose HV connections.
✅ Insulation Testing & Data Review – Critical for HV safety faults and misfires in hybrid circuits.
✅ On-Site Component Repair – HV relays, BiSG units, wiring, hybrid cooling pumps—repaired or replaced without recovery.
✅ Post-Repair Function Test – Full DTC clearing, module resets, and readiness checks.
⚠️ Ignoring Hybrid Faults? Here’s What Happens:
💥 Unexpected system shutoff while driving
💸 Misdiagnosed battery or inverter replacements
🔋 Total electric drive loss = petrol-only mode
🔥 Arc or fire risk from HV damage

⚠️ Plug-in Hybrid Fault Symptoms (P460e / P550e)
Range Rover PHEVs feature high-voltage battery packs, electric drive motors, and complex cooling and inverter systems. These are powerful—but fragile.
We commonly diagnose:
-
🚫 Won’t enter READY mode
-
⚠️ Hybrid System Fault / Restricted Performance
-
🔋 Battery not charging or draining rapidly
-
🔌 HV Interlock / Isolation fault
-
🔥 Coolant ingress in inverter or HV connectors
-
🛠️ Persistent fault codes after minor repairs
⚠️ Mild Hybrid Fault Symptoms (MHEV – P400, D350)
Mild hybrid models rely on a 48V electrical subsystem (BiSG unit + lithium-ion battery). These systems are often misunderstood by general garages.
Common MHEV problems:
-
🛑 Stop-start not functioning
-
🔋 48V battery not charging
-
⚠️ Energy Recovery / BiSG unit fault
-
🧠 Intermittent power dips / energy storage DTCs
-
🔌 Voltage sensor, belt, or hybrid ECU issues
