The instructions given by the FIA to Red Bull re the flow rate sensor problem were clear, the team disregarded them and so does not have a leg to stand on.
From
http://184.106.145.74/f1-championsh... Australian Grand Prix 2014 Document - 56.pdf :
"A) The team chose to run the car using their fuel flow model, without
direction from the FIA. This is a violation of the procedure within TD/ 01614.
B) That although the sensor showed a difference in readings between runs
in P1, it remains the homologated and required sensor against which the team is
obliged to measure their fuel flow, unless given permission by the FIA to do
otherwise.
C) The Stewards were satisfied by the explanation of the technical
representative that by making an adjustment as instructed, the team could have
run within the allowable fuel flow.
D) That regardless of the teamās assertion that the sensor was fault, it is not
within their discretion to run a different fuel flow measurement method without the
permission of the FIA"
In my opinion RBR were trying it on, they are used to pushing the regulations to the limit and have grown used to being able to persuade the FIA into making decisions in their favour regardless of whether they are legal or not.
