This is how to use Xprog programmer to read BMW CAS2 mc9s12dg256c.
- BMW CAS2 mc9s12dg256c

Reads good with Xprog m.
Xprog 5.55 is ok but new Xprog 5.70 better i think.
Step 1: Xrpog > Device > MCU/MPU > Freescale HC(s)2-secured > MC9S12-EEPROM-secured (at very bottom)
Step 2: Xprog > File >New Bin File.
Step 3: Xprog > Run > Read

PS: You may want to take a little more care with your connections. Cas is easy to kill. Your Vdd and BKGD looks to be bridging.
