⚡ BMW i3 Mobile Auto Electrician — Battery Diagnostics Middlesbrough

High‑Voltage Battery, Isolation, BMS & Charging System Fault Testing

📞 Call 07779 836677

A BMW i3 showing warning lights, reduced power, charging issues or refusing to go READY often has faults linked to the high‑voltage battery, isolation resistance, BMS, inverter, or 12V system.

Across Middlesbrough, we provide a mobile BMW i3 auto‑electrician diagnostic service, attending your home, workplace, supermarket, gym or roadside with full OEM‑grade tools.

We diagnose the real fault — not just clear the warning.

⚡ BMW i3 Battery & HV System Diagnostics

  • BMW i3 HV battery test — SOH, imbalance, module deviation
  • Isolation resistance testing — water ingress, HV leakage
  • BMS fault analysis — drivetrain malfunction, HV system fault
  • Inverter & motor diagnostics — torque limitation, overheating
  • Charging system test — AC/DC handshake, charge refusal
  • 12V system health check — common cause of non‑start
  • Cooling system check — thermal derating, pump issues
  • Full BMW i3 diagnostic scan — hidden faults, BMS alerts

🔧 Common BMW i3 Battery‑Related Issues We Diagnose

  • HV isolation faults — water ingress, corrosion, HV leakage
  • Drivetrain malfunction — inverter or HV battery issue
