Recently, some users have reported module damage while performing the Add Key function on BMW G-series BDC02 systems using Autel IM508 or IM608 tools.
Below are the main causes and important precautions to help you avoid damaging the BDC module during key programming.
 
⚠️ Common Causes of Module Damage
 
1. Not following the operation guide carefully
 
Incorrect wiring or skipping steps can lead to module or chip burnout.
 
Always follow the official Autel procedure and on-screen prompts exactly as shown.
 
2. Ignoring electrostatic protection
 
Static electricity in the work area can easily damage sensitive chips.
 
Always wear an anti-static wrist strap throughout the key programming process.
 
3. Improper grounding of EEPROM PIN2
 
The PIN2 of the EEPROM module must be connected to the designated ground line as shown in the wiring diagram.
  
 

Using a random or incorrect ground point can permanently damage the chip.
 
✅ Important Tips
 
Double-check all wiring connections before proceeding.
 
Keep your work area clean, dry, and static-free.
 
Carefully follow every step and prompt on the Autel device.
 
By observing these precautions, you can safely perform the Add Key operation on BMW BDC2 systems and prevent unnecessary damage.
