M Coupe, M Roadster & Z3

Information and matching of any difference occurring between kilometer (km) reading in the encoding connector and redundant value soldered in EEPROM can be reset by performing this test.

If "- - - - - - -" is displayed in odometer display, external and internal EEPROM values are identical. If there is a difference in readings stored in memory, value displayed is always the lower reading. Supplement "I" indicates that this is in internal EEPROM value. An "E" signifies this is an external EEPROM (encoding connector) value. In addition, if counter readings differ, manipulation point lights up.

After replacement of cluster or encoding connector, higher km reading in EEPROM can be matched to lower reading by holding down reset button when selecting test 09 for greater than 4 seconds. At this point, service interval data is also transmitted. After successful matching, manipulation point disappears. Replacement part must always have a smaller reading, otherwise vehicle-specific km reading is overwritten.
