Ricciardo excluded over fuel flow

F1 live stream
Ricciardo has been excluded from second place in Australian Grand Prix for fuel-flow irregularities. The team will appeal against the verdict. The stewards began an investigation post-race, after the FIA reported that Ricciardo's RB10 had "consistently" exceeded the fuel flow limit of 100kg/h mandated in the new 2014 regulations.

The FIA technical representative observed thought the telemetry during the race that the fuel flow was too high and contacted the team, giving them the opportunity to follow his previous instruction, and reduce the fuel flow such that it was within the limit, as measured by the homologated sensor – and thus gave the team the opportunity to be within compliance. The team chose not to make this correction.

It seems that the sensor was/might have been broken and the technical representative decided to tell Red Bull to tune down their fuel flow even though that same flow was deemed legal by that same sensor earlier in FP1. Red Bull did not agree with this and installed a new sensor. Then raced with the original sensor, which again said that the fuel-flow was too high. The technical delegates again told Red Bull to tune down the fuel-flow "such that it was within the limit". However, since Red Bull was convinced the sensor was broken they refused to do that. Instead they used the backup model specified in the rules. Now the stewards are arguing that switching to the backup model is their call to make and not Red Bulls, while Red Bull now basically appeals with the argument: "we did not break the fuel-flow limit, the sensor sucks, that's not our problem"
