The pointer is built into the instrument cluster and is self-powered by rechargeable batteries that store data in the memory for four months after the battery is disconnected. The indicator readings are reset using a BMW electronic key connected to the output «7» diagnostic pads. It consists of nine alarms (LEDs), five of which are green, one yellow and three red, as well as two illuminated displays located above them: OIL SERVICE and INSPECTION.
Operating principle
After the car has run the first 2000 km, after bringing the pointer to its original state, the indications in the form of the signaling devices and the indicator board illuminating should be interpreted as follows.
When the ignition is turned on, a number of green warning lights come on (maximum five), which go out after the engine is started. The number of warning lights that come on decreases as the vehicle is used, thus indicating that the service interval is approaching.
After all the green signaling devices go out, simultaneously with one of the boards, the yellow signaling device starts to burn constantly (it does not go out even after starting the engine). This indicates the need to carry out as soon as possible the maintenance operations corresponding to the illuminated display.
If the operation of the car continues, sequentially, with a monthly interval, the red signaling devices light up and do not go out. Do not operate the vehicle with the red warning lights on.
Maintenance interval
The pointer usually shows maintenance intervals in the following order:
- when the OIL SERVICE indicator lights up, change the oil in the engine crankcase and the oil filter element, and, if necessary, check the safety of the car;
- when the INSPECTION display first lights up, perform the maintenance operations provided for by the program «Check I»;
- when the OIL SERVICE display lights up again, repeat the operations indicated above;
- when the INSPECTION display lights up again, perform the maintenance operations provided for by the program «Check II».
Subsequently, repeat maintenance operations, alternating programs «Check 1 «And «Check II».
Note. On vehicles with a low annual mileage, the INSPECTION display lights up annually. In the atom case, you should run the programs «Check I» or «Check II», keeping their order. At the same time, carry out maintenance operations that are carried out annually or every two years of vehicle operation.
