Problem:

It is a 2015 MW X5 BDC immobilizer system. Tried to change km withYanhua mini ACDP2. Initial programming succeeded but failed to reset. ACDP gave the error "Reset FEM/BDC mileage failed”.

Image attached:

Solution:

First of all, you got the wrong connection of ACDP2 and FEM/BDC interface board.

Check the correct interface connection as following

Then if reset FEM/BDC mileage failed, you may lose FEM/BDC coding.

PerformStep 6: Remove EEPROM DataandStep 7: Recover Coding Datato restore coding. Make sure you back up original data before operation.

Restore the original data.

If restore coding completed, but still fail to reset mileage (see error image)

Check the BTLD software version. If theversion is 082, you cannot reset mileage by removing the BDC module.

If it is BDC 082 version, the mileage is reset via OBD. PurchaseBMW BDC OBD module 31.Go to BDC OBD (F Chassis) and reset km.
