Apparently. Jens Flottau from Süddeutsche Zeitung writes this today, citing "industry insiders" (rough translation by me):
Industry sources said a new software was introduced with the particular aircraft for Turkey that allowed military maneuvers from liftoff. According to reports, this software was faulty and caused during the first flight of the Turkish machine the failure of multiple engines. How many engines have failed exactly and for how long apparently is still not fully understood.
According to this information, the new software allows military maneuvers by changing the so-called trim of the aircraft, by shifting the center of gravity. This is done among other things by pumping fuel from one tank into another. There are indications that this pumping did not work correctly.
