Maintenance Service Reminder Reset - Description

The service indicator can only be reset using the reset mode in the instrument cluster or by using BMW hardware. This procedure applies to 3-Series from production date 9/99, and 5-Series and 7-Series from production date 9/00 (except 2002-05 7-Series and 2004-05 5-Series) without an engine compartment diagnostic connector.

• On models that still use the round diagnostic connector in engine compartment, use SIA reset tool to reset service lights. See MAINTENANCE SERVICE REMINDER RESET - PROCEDURE 01 .
• On models without the round diagnostic connector in the engine compartment, the use of the SIA reset tool is not possible. See MAINTENANCE SERVICE REMINDER RESET - PROCEDURE 02 .
• For 2002-up models with condition based service (CBS) interval system reset procedure, see MAINTENANCE SERVICE REMINDER RESET - PROCEDURE 03 .

Starting in 1983 and ending on some models in 1999, service indicator on instrument panel consists of 5 Green, 3 Red and one Yellow Light Emitting Diodes (LED) and the inscriptions OIL SERVICE and INSPECTION. When ignition is on, as many as 5 Green LEDs will light up. The Green LEDs go out when the engine is started. If the Yellow LED glows and one of the inscriptions comes on and remains on when the engine is started, maintenance service is due immediately. When maintenance interval has been exceeded (after approximately 1000 miles) the Red LED's will come on in addition to the Yellow LED as a reminder for servicing.

Beginning on some models in 1999, a new method for displaying the service interval is used. Colored LEDs are no longer used to display the amount of time until the next service or inspection is due. The actual mileage remaining until the next service will be displayed for five seconds when the ignition is first switched on. The text OIL SERVICE or INSPECTION will also illuminate to show which service is due. A minus symbol (-) before the mileage display indicates that a service is past due.
