Anyone shine some light on my problem??

I have a 2005 Volvo S40 2.0D with a siemens/comtinental ECU
When i read the map using Kess V2 5.017 and Ksuite 2.47 it gets a checksum error after already reading the map yet it saves the map to my computer.
If i put the map into WinOLS it says the checksums are ok.
Ive read that with the edc volvos you need to use the blue cable to connect to the ecu, is this the same for the siemens ecus too and is that what the problem is??
