Xhorse Multi Prog BMW CAS3 Chip Crack Failed?

 Here comes the solution to Xhorse multi prog BMW CAS3 chip crack failed problem.

 

 

Problem 1:

Read CAS3 0L15Y with multi prog, it says chip crack failed and asks to increase the voltage.

Problem 2:

Read and write a CAS3 from BMW 116 2007 model with multi prog…….. finally it manage to read and write (to remove ELV) but with problems. It starts reading the eeprom and it read it just fine,  the tool works great with this… but when i start to read the flash, the tool couldn’t read it and suggested me to increase the voltage, I increase the voltage and the half of my attempt to read the mcu the multi prog couldn’t do it.

Solution:

Bad connections. You need to clean off the coating bmw put on the pcb board and then it will work.

You will get chip crack error if a pin isn’t making a perfect connection. You can use a special pen that removes the coating on it.

Multi prog reads with no problem. Do not connect XCLS screen and check connections one of the pins is incorrectly marked in the xhorse description.

If pin is correct, then try to increase voltage to 4-5V, try again.

You can also use the XDNP11GL CAS3 solder free adapter.

 

 

Feedback:

Done, one pin has bad connection. Redo every solder.

After reconnecting all needles tried again and succeeded.
