Services Performed
  • – Vehicle is equipped with Dinan piggyback ECU. There appears to be no other physical modifications to the car besides a Dinan axle-back exhaust which does not affect vehicle emissions. – CEL present for fault 12BD60: O2 sensor before catalytic converter, electrical: open circuit virtual earth. O2 sensor and wiring appears in good shape visually. Code re-appears immediately after clearing codes. Recommend removing Dinan piggyback ECU prior to further diagnosis to determine if it is the cause before testing sensor/wiring.
  • Removed Dinan ECU, cleared codes, & road tested vehicle. No fault codes have returned. O2 sensor is functioning properly, but there may be an issue with the Dinan wiring harness or a software update required to eliminate the CEL when it is installed.
  • Tire pressure set to manufacturer recommended pressure
