State Inspection and Emission (I/M) Test Fails Due To an Invalid VIN Number. The customer of an affected vehicle may fail to pass an I/M test due to a non-compliant 17digit vehicle identification number (VIN) stored in the DME (Digital Motor Electronic). The VIN read out and displayed on the state test printout does not match the actual VIN of the vehicle. If the DME was reprogrammed using the previously available BMW service equipment (e.g., Progman, GT1), it is possible that only the last 7 digits of the VIN were entered into the DME, and positions 4 through10 may only contain default characters. For example: The state I/M tester or OBD scan tool may read out WBAAA00000A123456 instead of the correct full 17-digit VIN, WBAZZ03492A123456.
