Solution to X-prog M ECU programmer V5.48 failed to read BMW CAS4 5M48H ECU problem is provided here.
I tried to read CAS4 (2013 year from Motorola 5M48H) using XPROG 5.48, did not work!
I checked several times on HELP tab, I cannot find the problem.
Select all options 5M48H and disconnect the xprog unit, still not work
After 10 seconds license, the system prompt error message “Device is silent”
1. Xprog M 5.48 does read CAS4 5m48h. The problem may be the USB or computer issue. Change another USB cable or another Win XP laptop.
2. If Xprog V5.48 still fails to read, then update Xprog 5.48 to higher version V5.0/V5.50/V5.55 or read it with Xhorse VVDI-PROG programmer (this is the ideal ECU programmer for CAS4)
Here is the VVDI-PROG read BWM CAS4 5M48H video in action guide
