Test Group Identification: Notes

BMW supplies test group information in the following 6 categories:

• CATALYST MONITORING 
• MISFIRE MONITORING 
• EVAPORATIVE SYSTEM MONITORING 
• SECONDARY AIR SYSTEM MONITORING 
• FUEL SYSTEM MONITORING 
• OXYGEN SENSOR MONITORING 

Specific engine family test group identification number (for example: WBMXV02.8M52  ) can be found on emission label in engine compartment. To cross reference test group category (catalyst monitoring, misfire monitoring, etc.) see BMW TEST GROUP IDENTIFICATION  table.
