You need the BlackList Fix for your Xentry and DAS system. Please note that the given 870.exe file will ONLY solve this problem for Xentry. You can still have this error for older cars like W211.W203 if switched to DAS.
For DAS blacklist fix you can use the original Cal.sli from Xentry\BIN folder or the one which is packed in the 870.exe file and copy to DAS\bin folder.
TIP: You can open the 870.exe file with WinRAR.
Make sure to make a backup of the original, just in case.
Or use this attached file which will fix for both systems and in addition will make sure that Part_Z is selected in cal.ini for VXDIAG VCX SE in C6 mode.
If you had error 870, try either 870 fix program or blacklist.exe program.
Hope it helps!
