Did a 2008 E60 CAS3+ had to DOWNGRADE it took about 10min and programmed key successfully
Cas4 can only be done by reading DFlash from Freescale cpu then load into programmer software and generate key. It can no ne done by obd.
You need xprog or vvdi prog to read the dflash.
- BMW Multi tool
I use multi tool to downgrade the CAS on table by CAS plug and 12V, then i make key, downgrade process takes 30 min, making key takes 1 minutes the whole job is 31 min without opening the CAS.
I can do CAS4 all key lost as well with Multi tool, but u need the help of a DME, 10000% Success, job done on table, ADD key by OBD. I m using Dialprog, done 1 all key lost and 3 add key , not a lot of testing but so far so good.
It is a indisputable fact.
A multi brand key maker which can update cas latest by obd.
Work for me too… Add e91 cas3+ my07, cas2 e91 my06.
