The team is appealing against Daniel Ricciardo's disqualification from the Australian Grand Prix as it thinks it did not break the rules.

Red Bull reveals appeal plan

On Friday, Red Bull had to replace a fuel-flow sensor in Ricciardo's car after it failed during the first practice session.

Red Bull boss Christian Horner had already blamed the 'immaturity' of the sensor technology after Ricciardo's disqualification.

Horner admitted the team was now in an awkward position following Friday's failure, and says Red Bull wants clarification on how it can proceed to avoid further punishment without compromising its chances during the weekend.

"I think we will have that conversation with Charlie [Whiting, FIA technical delegate] beforehand," Horner said.

"It will be clear if we do see a variance, what are we going to do? Hopefully we can agree something that is sensible.

"We had a signal failure on Daniel's car this morning immediately, so we obviously have replaced that for this afternoon's session and I haven't had the results of that.

"Hopefully it is reading as per the fuel rail and will behave for the rest of the weekend.

"If it doesn't, we find ourselves in an awkward situation but it is one where we will try to work with the FIA, but again you are faced with the same dilemma as Australia a couple of weeks ago."

RED BULL: OTHER TEAMS SUFFERING TOO

Horner said Red Bull was not alone in suffering problems with the FIA-supplied sensors.

"Other teams don't talk to us too much. We are aware that other teams [had problems].

"We know Toro Rosso had two failures this morning. Sergio Perez's sensor failed for the entirety of the race and others were given other readings.

"The issue for us was that the sensor drifted, it wasn't an inconsistency, it was just a constant drift from the fuel delivery.

"We need a sensor that is consistent with the fuel rail, that is the most important factor. Thereafter we will have to make that judgement in the race depending on what the sensor is saying.

"If it is 0.25 per cent you can live with it, if it is two per cent then you cannot live with it. It depends on what the value is."
