No, it shouldnt affect ADSL provided you put a filter on it in the usual
way.
At worst a rectified loop condition will prevent all your phones from
clearing down the line when you hang up or your line might automatically be
answered mysteriously after a single ring, it depends on the polarity of the
wires to pins 2&5 of the offending item (sky box in your case)
As you are not getting either of the above affects I wouldnt worry too
much, I suspect the 17070 test can detect very small amounts of DC
asymmetry.
Two other things spring to mind.
Lightning damage?
Moisture ingress to Digibox?
