The code will still be there because the adaption needs to be cleared. You can do a hard reset of the computer by touching the negative battery cable to the positive battery post for 5 minutes this will discharge the capacitors and reset the system. If this does not work then a shop will need to clear it.

Please let us know what happens.

Cheers
