version tips

I need to read and write via serial to a 2.0 tdi 170 hp siemens ppd 1.2 I have seen so many versions 2.10 to 2.13, the sellers with the j-link who is not, and everyone says, token unlimited, or take the classic galletto v54? From the outset there I have to work then I don't want to disassemble the ecu, but a good clone that's me doing the work in serial safely.
Accept advice
grz in advance

Hello, a good tool can't find it from the east, beautiful and ready, we need to review the hw and make the changes.............

all working good

question.... but the fw 4036 is equivalent to the sw 2.08 or higher??

I confirm Kess v2 FW 4.036 = on their computers 2.08
Ktag FW 6.070 = on their computers 2.10
