Look for any values that are outside of the normal range, as this could indicate a problem. Pay attention to patterns and trends in the data. For example, a steadily increasing coolant temperature could indicate a cooling system issue. Use the live data to correlate with other symptoms or trouble codes. For example, if you have a trouble code for a misfire, you can use the live data to monitor the performance of the ignition coils and fuel injectors. By learning to interpret live data, you can gain a deeper understanding of your Mercedes-Benz’s performance and diagnose issues more effectively.
