You need the BlackList Fix for your X-ENTRY and D-A-S system. Please note that the given 870.exe file will ONLY solve this problem for X-ENTRY. You can still have this error for older cars like W211.W203 if switched to D-A-S.
For D-A-S blacklist fix you can use the original Cal.sli from X-ENTRY\BIN folder or the one which is packed in the 870.exe file and copy to D-A-S\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!
