W164 CGW 2007+ algo

[wsc]

hello guys
Does anyone know the algo for services and days ?

[wsc]

i suppose none knows the algo.......:)

[Room]

From 4EA there are 5 records of 10 bytes each plus 1 Byte is the total number of services.
You dump has 4 services.
record :
2 swap bytes = Kilometer reading /100
3 swap bytes = Remaining distance (signed value)
2 swap bytes = Remaining time (signed value)
1 byte = Product of quality factors
1 byte = Total of replenishments
1 byte ??

thank you my friend Room
i get it , i still looking for the assyst+ , maybe is most complicate algo

I think assyst+ data is stored in flash, not in CPU.

and what is mileage from this car?

[wsc]

i found the last service 6C9 and 845 18 bytes: 2 bytes the days , 3 bytes the service, 2 bytes ??, 2 bytes the distance from previous service,2 bytes the days from previous service, 4 bytes the system controller (hex string) and 3 bytes the workshop key (i can not confirm the coding but with Das i saw C5M061, the hex value is AD 08 08


I also think that the missing part of assyst+ is stored in flash
