The defective air line connector, according to the statement, resulted in a loss of control over the turbocharger. The team isn't sure why the connector failed and is continuing to analyze the component to get down to the root cause, the team said in the statement.
During the race, the team was able to get the No. 5 car running again by modifying the control settings. The fix, however, came a little too late as the vehicle could not complete the lap under Le Mans' maximum final lap time of six minutes and limped its way to 45th place.
While the team is working hard to find the fix – to avoid a similar type of failure in the future – it claims there is no relation to the engine issues that were experienced by the two TS 050 cars at Spa during the World Endurance Championship in May.
