Fuel sensors a known problem - Boullier

Thursday 20-March-2014 09:27

Eric Boullier, the McLaren Racing Director, has revealed that all the Formula One teams knew that there might be problems with the fuel flow sensors during the initial part of the 2014 season.

Boullier's comments come after Red Bull's Daniel Ricciardo was excluded from last week's Australian Grand Prix after the Milton Keynes team ignored a FIA request to decrease its fuel flow since Ricciardo's car was consistently achieving a flow of more than the allowed 100 kg/h.

Red Bull maintained that they were complying with regulations and that the FIA was receiving an incorrect reading from a faulty sensor, but despite finishing in second place, Ricciardo was excluded from the race after the FIA ruled that their advice was consistently being ignored.

On Thursday, Boullier confirmed to that all the teams were made aware of possible sensor problems and that the FIA stated during pre-season testing that sensor data may not be ignored.

"It's clear that it was raised early enough that there was a little bit of an accuracy issue between the different sensors, but we have been working closely with the FIA since early January to make sure that we understand the needs and understand if we could improve the system," Boullier told

"All the teams were obviously welcome and working all together.

"In the end the FIA took a position in Bahrain at the second test where it was clear that the fuel flow sensor would be the reference and had to be used, so we knew that there was a little bit of need to filter a little bit the signal; there was a little bit of deviation if you want and we had to be careful with the fuel flow.

"In the end we have been fully compliant during the race and the whole weekend actually like most of the teams."

When asked if he felt sympathetic for Red Bull and Ricciardo, the former Lotus boss said that he prefers to focus on his McLaren rather than getting involved with other teams.

"To be honest we have enough on our plate and we do our job to be compliant with the regulations," Boullier added

"This is just a matter which is between the FIA and Red Bull and we don't want to comment at all."
