Red Bull team principal Christian Horner has accepted McLaren's apology over the glitch that affected Mark Webber's start at the Australian GP, but admits he will be a happier if they have sorted out the problem once and for all.
Starting P2 on the grid, Webber found himself down in seventh place by the end of the first lap and it was revealed after the race that a problem with the electronic control unit (ECU) affected compromised his start.
McLaren Electronics Systems, a division of the McLaren Group which supplies standard ECUs to all F1 teams, confirmed that a software problem contributed to Webber's woes and apologised to both the driver and the team.
Asked by Press Association Sport as to whether that was sufficient, Horner said: "It was gracious of McLaren to stick their hand up and apologise. The apology was accepted.
"It was an issue, and hopefully they will get on top of them quickly, with the most important thing being to learn from what happened in Melbourne."
He added: "I haven't spoken to the other teams, but there are glitches, and yes, it is complicated software.
"Unfortunately, we buy a product and you expect it to be right."
Despite the apology, Horner admits they have had plenty of problems the system in the build-up to the season, but hopes McLaren can sort out the problem permanently.
"There are always reasons behind everything," said Horner.
"We ran the ECU for the first time at the young driver test last year where there were an awful lot of problems.
"They've worked very hard to get on top of those issues, and the majority of them have been sorted.
"But it is frustrating when an issue like we had compromised a race start and the preparation for the race in Melbourne.
"But McLaren took it on the chin, apologised and said they are working hard to get on top of it.
"We will respect that, accept the apology, and if we can do anything to help support them then it's in our interest as well."
