We have just released a firmware update that resolves a known bug that impacts BMW N54 IKB0S IS ECUís. When this bug is encountered, the AccessPORT no longer recognizes that it is in an installed state immediately after the AccessPORT has been Installed or after a Change Map routine has been completed, rendering the AccessPORT inoperable. Firmware release 188.8.131.52-4040 specifically eliminates this bug on IKB0S IS ECUs and we strongly recommend verifying your AccessPORT is up to date on the latest release firmware before installation. This firmware is compatible with all BMW AccessPORTs.
If your AccessPORT is experiencing the symptom of this bug, please contact a COBB Tuning Customer Service Representative at 866-922-3059 to assist in resolving this issue.
