I’ve have only been using Yanhua ACDP mini programmer a month but so far no issue. I bought really for CAS4 as I have other programmers for keys, ISN etc. I’ve had no issues with it so far and have done cas4, cas3, frm, key renew, retrieved ISN from MSD85.
I use on laptop not phone and have very happy with it so far, the PC connection is wireless, 2.4MHz, will not work on 5G. Took me forever to find that out. It is better as I don’t have to worry about transferring files back over to it from phone. You can always upload files to phone so you have them both devices.
Make sure you get any pins detected, I could understand if maybe 1 or 2 pins not detected but if not able to detect any that would point to bad unit. Be sure to use their cleaning tool for pin connections, I tried without doing when I first got it and noticed I would get no detection on certain pins. Also make sure switch on side of OBP+ICP is not in can mode. So far the hardest part of using this tool was the initial setup and authorizations, been flawless so far.
- Tried several CAS4 to Read without any problems, Mileage reset works too.
- Create successfully keys on FEM/BDC and CAS4
- Reading eprom cas4 and make a key for f11 so far done.
Cant say much more.
cas4 reading eprom compared with vvdi reading and its matching 100%
