Xhorse Multi Prog BMW CAS4 Adapter Chip Crack Failed

 Problem:

Read BMW CAS4 module with Xhorse Multi Prog and XDNP12 CAS4 solder free adapter.

Pins flown in/cleaned, in the pin test passes ok, Procka Mask selected correctly, external power power plugged in – processor detects as unknown and does not want to secure.

Error chip crack failed.

Any advice?

Solution:

Double check connection, if pin test passes ok,  when using solder free adapter, try to lower VPP voltage to 3.3V and VCC to 5V. 

You have to manually change the values of vcc and vdd.

Or read directly without an adapter.

VVDI Key Tool Plus Add 2019 Porsche Cayenne MLB Key

 User review:

“Porsche 2019 Cayenne MLB add key success using Xhorse VVDI MLB Tool + VVDI Key Tool Plus.

Solder to the chip directly. Capacitors removed and reinstalled (a pain). Better to order new capacitors (0.1uF, 0603 package capacitor) in case they get lost or damaged. Had to put them back if it is a Cayenne.

Did a Lamborghini Urus prior and broke the shell but had replacement aftermarket. At the time I would of rather broke the shell than risked damaging the chip. Had a new replacement Porsche shell on standby but I managed to cut away super clean and reuse original shell. After you generate the dealer key you have to learn 2 keys next as it wont let you learn the newly added key alone. Learning sensor is on cupholder closest to driver for reference.”

Xhorse Generate Hyundai 47 Chip using VVDI Super Chip

Question:

Will Xhorse generate Hyundai 47 blade chip using VVDI Super Chip XT27A. Tried all of them didn’t work.

Here is the clue.

Xhorse XT57B definitely will do but it is not available yet. The XT27A also works.
Here is the tip to generate Hyundai 47 with XT27A.

Try with New 7938 -xt27. It’s working.

Generate ID47, then tap “New 7938 chip” and then “Generate”. Not ID47 Hyundai.
