Description

BMW M5 ECU Water Damage Repair / Replacement Service DME MSS65

  • Water damaged control circuits – these are placed at the bottom of the ECU so when the drains are blocked, it causes these areas to get damaged.
  • Continuous open circuit faults on injectors or coils.
  • No communications through the diagnostic connector.
