Resetting the Service Interval Indicator (SII) on Your BMW

20 Pin Socket Deletion

Model & Production Date:
E46 from 6/00
E39, E52, E53 from 9/00
For model year 2001 the E39, E46, and E53 will eliminate the 20 pin diagnostic connector from the engine compartment.

On 2001 3 Series and 5 Series vehicles without the diagnostic connector in the engine compartment, the SII reset tool can no longer be used. Instead, the SII can be reset with the trip odometer reset button in the instrument cluster, following the instructions listed below:

• The ignition key must be in the “O” (“off”) position.

• Press and hold the trip odometer button in the instrument cluster, and turn the ignition key to the “1” (accessory) position.

• Keep the button pressed for approximately 5 more seconds until any of the following words appear in the display: “Oil Service” or “Inspection”, with “Reset” or “Re”.

• Press the button again and hold for approximately 5 seconds until the words “Reset” or “Re” flash.

• While the display is flashing, press the button briefly to reset the Service Interval. After the display has shown the new interval, the following will appear in the display for approximately 2 seconds: “END SIA”.

The system can only be reset again after the vehicle has been driven approximately 50-75 miles (consumes at lease 2.5 gallons of fuel). If the display shows “Reset” or “Re” when resetting, the minimum driving distance has been fulfilled and the system can be reset again. It is possible to interrupt and end the reset procedure by changing the position of the ignition key.

Note: An alternate method to reset the SII is to use the OBD adapter harness (available under P/N 90 88 6 614 300, sent to all BMW centers as part of the Automatic Tool Shipment Program) together with the SII Reset Tool (available under pin 88 88 6 621 110). Fasten the Reset Tool to the OBD adapter harness, and then connect the harness to the OBD/diagnosis socket in the driver’s footwell. Reset the SII per usual procedure.
