Packing List:

1 * Multi Tool for BMW Main Unit

1 * USB Dongle




Q1: Could you please let me know if Multi Tool for BMW has EWS function ?

A1: Yes, it can do EWS, you need to detach the device then connect with CAS socket to read EWS data.

Q2: Can Multi Tool for BMW do BMW cas3 and cas3+ keys? For example, the 868 MHz key.

A2: Yes, BMW MULTI TOOL can do most kinds of BWM keys.

Add Key OBD:

cas3+ encrypt version -> no need to update CAS (no need for key cycling)

cas ISTAP4x version -> need to update cas (no need for key cycling)

Lost Key OBD:

cas3+ encrypt version -> no need to update CAS (need to cycle key UPTO 16 times)

cas ISTAP4x version -> need to update CAS (need to cycle key UPTO 64 times)


Add Key Dump Method (Lost or Working Key):

cas3+ encrypt version -> need to write back to CAS (needs either -working key / known ISN / ECU dump / or cycle UPTO 16 times)

cas ISTAP4x version -> no need to write back to cas (needs either -working key / known ISN / ECU dump / or cycle UPTO 64 times)

So the 64 cycle is really to save you having to downgrade the CAS but you still need to manually read the CAS for this option. For me this is still the best  way as theres no way I would downgrade the CAS (unless you made it very clear what this meant to the client)
