FAQs:
Q: Can’t read with another device? Do I need module 3 if i have other tool to back up engine eeprom data?
A: Step 1:Requires module 3 + B48 interface board to back up the original BMW engine EEPROM data.
If you have another tool to backup engine eeprom data, you don’t need to buy module 3, just buy module 38 + BDC2 test platform.
Q: if i have my own bench or if i do this job on the car it’s means I don’t need this bench test platform?
A: No, you still need to get the BDC2 test platform because it also comes with license A504 for AKL.
Q: It is necessary to have all the adapters for each version of the BMW engine to make the first stage?
A: Most BDC2 engine are B48 type with SPC5777. So B48 interface board is widely used.

A: No, you need to read eeprom data from B48 DME not ISN (in step 1).
Q: Step 7 reset EGS EWS do i need other module?
A: No, don’t need other modules. Install BDC2 module to car and reset EGS EWS via OBD.
