As a measure for determining the service cycle, the microprocessor uses not only the mileage but also the operating conditions, such as the duration of the trip or the driving style of the vehicle.
In the workshop, after an oil change or after maintenance, the data in the service interval determination system is erased. To erase the data, a diagnostic electronic device is required, which is available in workshops. In addition, in the workshop, you can "reset" the data if you perform maintenance yourself.
Anyone who does not want to follow the INSPEKTION indicator in the car can perform maintenance according to the instructions provided here. In this case, the frequency of preventive maintenance corresponds to the oil change intervals (OILSERVICE), and the frequency of maintenance is the INSPEKTION frequency.
Attention: To ensure optimal engine operation, it is recommended that you visit a specialist workshop as part of a technical inspection to read the data from the diagnostic system memory unit. This will allow you to detect faults that are automatically overcome when running the emergency mode program. The consequences of this may be that the engine will not operate under optimal conditions (for example, increased fuel consumption).
