diagnostic software ford focus

[columbo25]

Hi all,

i need your help. I have a ford focus diesel with mil light on.

What is the best diagnostic software to make some diagnostics to the diesel-ecu. The customer gave me a fault code P2459 but my Bosch-tester can not handle this .

I am appreciative for any help.

thanks
