Red Bull says that the FIA cannot dispute that there are problems with Formula 1's fuel sensors, following another failure for the team in the Malaysian Grand Prix

Red Bull believes F1's fuel sensor issues are indisputable

Just a fortnight after Daniel Ricciardo was disqualified from the season opener in Australia for breaching F1's fuel-flow limit, the Australian's fuel sensor broke completely at Sepang on Sunday.

It meant the team had to rely on its own fuel-rail data readings to show its compliance with the regulations, although unlike in Australia this time the FIA accepted this course of action.

Red Bull boss Christian Horner said the ongoing issues his team has faced are frustrating.

"It failed prior to the race," he said. "We informed the FIA about it and we asked the FIA if we could revive it on the grid by effectively power cycling the car.

"We did that at the start of the race but it didn't come back to life. So, the sensor didn't work the whole race.

"I think it clearly demonstrates that there are issues with these sensors."

While rival teams have not encountered the kind of troubles that Red Bull is facing, Horner said that there is no explanation as to why his outfit was suffering more than others.

"I've no idea why," he said. "Obviously we have a lot of data here to go away and look at.

"Theoretically there should not be a reason, but we need to look and understand it. Everyone else is happy with the sensor apparently.

"But Toro Rosso had two failures earlier in the weekend, and there have been other issues up and down the pitlane.

"They are the only ones we know about. But it certainly isn't unique to Red Bull."
