Hey Guys,
I have an R56 Mini that I need to adjust km’s after a CAS replacement.
I have opened the Kombi and read the 080D0WQ eeprom and saved the file.
I edited the km’s as needed and saved the file.
Do I write the modified file back or do I have to erase the eeprom first ?
Should I remove the eeprom from the Kombi and place in adapter ? (I read it in circuit)
Many Thanks

Remove eeprom and just write the modify data or file...programmer automatically erase

Another repairer fitted a donor CAS that had higher mileage and the Kombi took the higher mileage from the CAS.
The car still didn’t start so the owner towed the car to the dealer and they fitted a new CAS but couldn’t correct the mileage.
The car has now come to me to correct the mileage.

One last question please.
It’s has CAS3+. When I read the CAS and modify, do I only need to write back the D Flash ??
No need to write back P Flash ??

Many thanks for helping.

Only D-Flash
CAS set mileage that you want and CLUSTER set 0

I always did the opposite and it worked every time (CAS set 0, Clusterset milage)
Is it wrong how I proceed?

I set the CAS to 0 and the Kombi to the km that I wanted and it worked fine.
I believe you can also do it the opposite way and that works fine too.
Hope this helps

yes in this case you need to edit cluster eeprom -->save and write eeprom back--->read again to confirm changes
then read CAS eeprom -->edit-->save--->write eeprom back (read again to confirm changes also)
then connect both back to car.
