Hi, need to do a bmw x3 2012 with cas4 module. Now i know by obd it is a risky job.
To do it with less risk wanna do it on bench. I got the vvdi prog, but still risky bcs need to remove components. Does anyone know a tool that read on bench with no components te remove. Thanks

If is CAS4+ you will need ISN or working key
ACDP is great for CAS4 in my experience.

Hello, I did not buy this apparatus, but there is no need, you do not need to remove any capacitor in the vvdi prog connection diagram.

Hi musti, in the vvdi prog you can find 2 diagrams (5m48h) where you dont have to remove anything. Is this always? I dont have done any cas4 before.

Just read vvdi prog manual. It say if can't crack MCU, then need to remove 1 resistor. So it does not always work without removing. When I do such work, I always remove that resistor before trying.
Remember your voltage must be over 13volt to get the “Cas” to wake up. So your power source is best tool to get to read mode.

Never had problems with 12v 2a
Cas4 buy for test - vvdi2 read on table, downgrade - all ok. Before use vvdi2 im read mcu and save flash and eeprom. Im load back saved file using vvdi prog, UPA-S - all OK. After load org file, vvdi2 again downgrade cas w/o problem.
