McLaren driver Jenson Button says his retirement from the Austrian Grand Prix was duly precautionary, as he did not want to cause damage to his power unit following a sensor failure.
An intake system sensor failure struck his McLaren during the early stages of running at the Red Bull Ring and, with the squad having fitted a new power unit to his car over the weekend, Button did not want to cause further damage ahead of his home race.
"Nothing was broken on my car, but something was wrong – and the switch-changes didn’t make any difference," he said.
"So the team took the decision to retire the car – we’d fitted a brand new engine this weekend, and we didn’t want to unnecessarily damage it, so we decided to stop."
After one of the team's worst races in its Formula 1 history, Button is sure McLaren's form will improve at Silverstone.
"Silverstone will be another step forward," he said. "Hopefully, we’ll have got rid of our issues so I can have a stronger race in front of my home crowd.
"And, after that, Hungary is a circuit that should suit us, so we can get a good result there."
