The technical rumour mill in the paddock suggests that Renault is less than pleased with Red Bull's installation of the control electronics in its 2014 car.
While this is just a rumour, Red Bull has done the fewest laps of any of the teams that has run so far, so it's clear something has gone wrong.
Changing an installation like this is not easy because there simply is not any spare space left over in a car, which means if this is at the root of the problem Red Bull will almost certainly have to make a fix work with what space it has.
