VVDI2 BMW+CAS4 authorization plus VVDI PROG FAQ

One beginner asked some questions on VVDI2 BMW+CAS4 authorization plus VVDI PROG and answered by xhorsevvdi.com engineer, they must be useful for more and more beginners, so I’d like to share here.

Question: What product do I need to edit/ correct mileage in BMW (e-series, f-series – CAS3,4, FEM/BDC) and clusters ?
I have found this:




Yes, you are recommended to use VVDI2 BMW+CAS4 authorization plus VVDI PROG bundle package.

Which aspect you want to know?


1] to change KM is enought , to modify CAS and clusters? other ECU in car will take km from CAS?

2] Which BMW needs to desolder eeprom (CAS or clusters) – only F-series?

3] its only up to CAS4 module, so If I will need to modify odometer on cars with FEM/BDC module, it will be enought to buy some sw/firmware upgrade – which you will send me, and thats it?

4] when I would like to modify the BMW  G-series , it will be still possible with bought HW – viz the URL? and again, only new software/firmware will be needed?

5] Will the VVDI come with some tutorial, how to modify mileage of car?

Thank you

Question: If I need to correct KM / mileage on cas4 or fem , it has to be done also on eeprom on cluster instrument. Do I have to buy also VVDI programmer, or only VVDI2 ?

Answer: for CAS4,we have said, immo or change km both need to use vvdi prog to read dump file.

Maybe BMW FEM also need platform cable to work stably.
