Christian Horner has blamed the FIA for the fuel flow row which led to Daniel Ricciardo's exclusion from the Australian Grand Prix.

Ricciardo originally finished second in the race - his maiden F1 podium - but was later excluded as the FIA claimed that his car "exceeded consistently the maximum allowed fuel flow of 100 kg/h", breaching technical regulations. However, speaking in the paddock after Red Bull had confirmed its intention to appeal the decision, Horner said it was a problem of the FIA's making.

"These fuel-flow sensors that have been fitted by the FIA have proved problematic throughout the pitlane since the start of testing," Horner said. "There have been discrepancies in them, even unreliable, and I think some cars may well have run without them during the race itself, or even failed during the race itself.

"We had a fuel flow sensor fitted to the car that we believe to be in error. We wouldn't be appealing if we weren't extremely confident we have a defendable case. It's just extremely disappointing this has happened. It's certainly no fault of Daniel's. I don't believe it's the fault of the team. I believe we have been compliant with the rules and the documents and investigation that will be submitted within the appeal will demonstrate that."

Horner said Red Bull believes there was a "significant discrepancy" between the sensor reading and the actual fuel flow, and as a result opted to ignore the FIA's guidance to reduce the fuel flow.

"It is immature technology, so it's impossible to rely 100 per cent on that sensor which has proven to be problematic in almost every session we have run in ... So it's surprising this stance has been taken.

"[The FIA] informed us, but we informed them we had serious concerns over their sensor. We believed in our readings, otherwise we faced a situation where we would have been reducing significant amounts of power into the engine when we believed we fully complied with the regulations."
