BMW F02, mileage problem

[rtr989]

Hello!
Have some problem, original mileage is 109660km.
Installed can filter to the CAS4 and mileage changed to 60750km, all is fine.
Car goes out, 2 months later mileage is 62500km.
Now, after changing the battery, mileage - 60750!
I put back original dump to 35160 eeprom, mileage is 109660km, i drive car for 2km, on the dash 109662, i disconnect battery for a few minutes, after power back on the dash 109660km, i drive another 2km and read the eeprom, mileage on the eeprom does not change!
You can see all dumps in archive.
What it can be? Is may be problem in 95320 eeprom or in can filter?
Please help!
Thanks!

i remove can filter from the cas, in the dash i put original dump with 109660km, all is ok, no dot on the dash, no errors.
i drive for 1km, on the dash 109661, disconnect the battery, connect the battery, on the dash 109660!

You need to drive more miles to get sync between dash and cas.

1 km is not enough to be dumped into the eeprom. When you disconnect the battery it erase the ram memory and when you connect it back it the cpu reads it from the eeprom again. You waste all your time driving 1 km and disconnect the battery numerous time instead of driving more. Drive for example 20 km and disconnect the battery and if it comes back to your original number then you can say that you have problem.

16 km is enough but if you wanna drive more drive 32+ km.
