In addition to the mileage of the vehicle, the operating conditions, such as short or long journeys or the driving style of the driver, serve as a criterion for calculating service cycles for the microprocessor. The scope of the said maintenance work is given in the service book.
In the workshop, after an oil change or maintenance, the display of the service interval indicator is erased. Clearing the display requires an expensive electronic tool sold through BMW repair shops. However, authorized BMW workshops are obliged to reset the display intervals free of charge on request, even if the service was carried out by themselves.
If you do not want to follow the indications of the BMW interval indicator, you can carry out maintenance or service according to the given or lower intervals. At the same time, given here «Maintenance» corresponds to the maintenance of a BMW car with an engine oil change, and the above «Service» - maintenance 1. At the end of the maintenance card are rarely performed maintenance items 2.
Note: In order to guarantee optimum engine performance, we recommend that you visit a BMW workshop when measuring exhaust emissions and interrogate the fault code memory there. In the engine management, malfunctions can occur imperceptibly, which are automatically ignored when switching to a backup program. As a result, the engine does not operate under optimal conditions (has higher fuel consumption). When polling the memory device for fault codes, such faults are easily detected.
