How Yanhua Mini ACDP solves data loss problem of BMW CAS4

Hello, I recently experienced a data lost with Yanhua Mini ACDP BMW CAS3+. This CAS3+ is easy to fix. But I'm wondering what can I do if I had problem with CAS4+ or FEM/BDC module.

We are asking if there is a solution to fix the problem...

Solution

• If CAS4/CAS4+ coding data loss due to transmission interruption, go to recover data in Mini ACDP, the vehicle can back to normal.

Path: BMW >> CAS1~4 >> CAS4/CAS4+ >> OBD mode >> IMMO/Mileage >> Recover coding data

• If FEM/BDC transmission break, DO NOT exit and wait for 15 minutes. The ACDP back-end will run automatically.
• If FEM/BDC data loss, go to recover EEPROM & coding data in Mini ACDP with a smart phone. The vehicle will return to normal.

Path: BMW >>FEM/BDC>>IMMO/Mileage >>Mode 1: add key >> FEM/BDC initial programming process >> Method 2: manual single step operation >> Recover EEPROM data/ Recover coding data
