🚨 Range Rover Sport PHEV & MHEV Fault? Mobile Hybrid Repair UK

Hybrid fault on your Range Rover Sport? Car stuck in restricted mode or won’t charge?
Whether you drive the PHEV (P460e / P510e) or Mild Hybrid (D300, P400 MHEV), we handle complex high-voltage faults and electrical issues on-site, across the UK.

📞 Call 07421 186356 – UK’s Mobile Land Rover Hybrid Electrical Specialists.


🔧 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
🧯 Immobilised with “Hybrid System Fault” on dash

⚠️ 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
