Service Indicator

Print

The Service Indicator must be reset after the service is completed. This will restore the Service Indicator to its baseline and it will start to calculate the new service interval.

A special tool is required to reset the lights. The tool is available from the dealer, specialty retailers and mail order. It is not difficult to use, but it can be pricey. If you do not decide to purchase the tool, it is sometimes possible to borrow the tool from a local BMW club or have your dealer or local shop reset the lights for a nominal fee.

PROCEDURE



The following procedures are for use with the BMW reset tool. Other tools will be similar or identical in operation. Follow the instructions that come with the unit you are using.

Be sure that you are doing the correct reset procedure for the correct service. If the wrong button, OIL SERVICE or INSPECTION is depressed, it cannot be corrected. This will not harm anything, but it will make the service interval incorrect.
