Networking 

• The oil sensor (oil level, temperature and quality, B40)  are read in by the ME-SFI [ME] control module (N3/10). The "oil level", "oil temperature" and "oil condition" (oil quality) values are sent to the CAN engine compartment in the form of a message by the ME-SFI control module (N3).
• The coolant temperature sensor (B11/4)  is read in by the ME-SFI control module (N3/10). The temperature value is sent to the CAN engine compartment in the form of a message.
• The sensor for the crankshaft position (L5) is read in from the  ME-SFI control module (N3/10). Via sensor impulses, the ME-SFI control module (N3/10) calculates engine speed  and sends a corresponding message to the CAN engine compartment.
• The four wheel rotation signals  (L6/1, L6/2, L6/3, L6/4) are read in by the SBC control module (A7/3n1). The SBC control module (A7/3n1) sends the four wheel speed signals via the ESP control module (N47-5) to the CAN engine compartment. The instrument cluster (A1) receives these messages and calculates the vehicle speed and traveled distance based on this data.
