🔧 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.

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
