McLaren has chimed in on the fuel flow controversy.
Now, Mercedes-powered McLaren says it was aware of some problems with the sensors for some weeks.
Former F1 driver Mika Salo thinks the Ricciardo controversy will not be the only fuel-related rule drama in 2014.
"I believe we will see it quite a lot," he told the Finnish broadcaster MTV3.
Salo said Red Bull will appeal the disqualification, so "let's see what the FIA does. The teams have complained about it a lot."
However, McLaren team boss Eric Boullier insists: "The FIA made clear in Bahrain that their sensors were the only reference for the calculation of the flow.
"We knew we had to be extremely careful," he is quoted by Italiaracing.
"It is true that there were some problems, but it is also true that in the end we were consistent (with fuel flow) during the race and, like almost all the teams, even during the whole weekend," the Frenchman added.
