To reset the ECU of a Vauxhall Insignia, first, disconnect the negative terminal of the battery and wait for about 10-15 minutes to allow any residual power to dissipate. Reconnect the battery terminal, ensuring a secure connection. You may also want to use an OBD-II scanner to clear any fault codes, which can further help in resetting the ECU. Finally, start the vehicle and let it idle for a few minutes to allow the ECU to recalibrate.
