We always recommend reverting your ECU back to factory specifications before flashing with the Accessport. The errors below are common on a non-US BMW that had a previous flash tune, and then used an Accessport. Because the AP did not save and modify the non-US ROM, a US ROM was used to flash the car. The error codes are caused by the non-US vehicle not having all of the same emissions equipment as a US car. The fix is to uninstall the AP and have a dealer flash the vehicle back to stock.
