Question:
VVDI BIM TOOL, I can’t read and reset mileage on CAS 3, I did connect with GODIAG CAS3 Test Platform and 100kbps
Here is the Answer:
To repair KM for BMW CAS3/ CAS3+, users need other tools like VVDI PROG or Multi Prog.
Steps:
1) Record the KM information displayed in instrument, take instrument away from car avoid synchronize KM with CAS automatically
2) Set CAS KM to 0 (you can do this via OBD or EEPROM dump, select correct CAS version)
3) Read instrument EEPROM dump by programmer then save EEPROM dump you read, usually it use M35080 chip
4) Select File Change KM ->M35080 (Instrument) and load EEPROM dump saved in step 3
Attention: this type instrument have 2 algorithm for KM, Algorithm 1 and Algorithm 2, you need try different algorithm to check the Old KM in file value, which one is nearby the KM (write in step 1), which is the right type. Change new KM with the right type
5) Input new KM
6) Press button “Change KM” and save new EEPROM dump
7) Write new EEPROM dump to M35080 chip
8) Put your instrument in car
9) Finished
Done! Hope this helps!
