Autel IM608 Recover BMW FEM/BDC after Smart Mode Failure?

 Problem: A user tried to add a key to a 2016 BMW X6 using Autel IM608 with XP400 Pro and GODIAG FEM/BDC Test Platform in Smart Mode. The key reading step failed, and after restarting the process, the BDC module became unresponsive.

Why This Happens:

Smart Mode does not back up the full EEPROM data unless the module is benched. If critical data is missing, the process can permanently damage the module.

Recommended Approach:

• Do not use Smart Mode for BMW FEM/BDC modules.
• Always use Manual Mode to read and save EEPROM data first.

If the EEPROM is Already Corrupted:

1.Write the original EEPROM data back if available.

2.If not, use a compatible EEPROM dump from an identical model or replace the BDC.

3.Reconnect the module, open Expert Mode in Autel, and run the BDC repair function (with external power connected).

4.If repair fails, try another known-good EEPROM file and repeat.

5.Once repaired, restore coding and program keys using Expert Mode only.

Critical EEPROM Reading Tip:

• Always read manually via system selection.
• After reading, take photos of the first and last data sections, then read again and compare. Repeat until the data is consistent.
• Only write a verified good file to avoid corruption.

Does Yanhua ACDP2 mileage calibration support 2024 BMW?

 The Yanhua Mini ACDP2 can calibrate BMW ID7/ID8 vehicles, but some BMW vehicles from 2024 onwards use ID8.5 (for example, the 2024 BMW X5/X6/X7). So, does the Yanhua Mini ACDP2 support BMW ID8.5?

The answer is no. As of the time of writing in September 2025, the Yanhua Mini ACDP2’s mileage calibration function does not yet support BMW ID8.5.

So how can you tell if your vehicle has ID8 or ID8.5?

A relatively simple method is to check the climate control interface on the vehicle’s central console (in-vehicle infotainment system) after starting the vehicle. If the climate control function is displayed as text, it indicates ID8; if it is displayed as an icon, it indicates ID8.5.
