Red Bull’s KERS problems now fixed – Marko image

( Red Bull has fixed its KERS problems ahead of the weekend’s Turkish grand prix, the team’s F1 consultant Dr Helmut Marko has confirmed.

The championship leaders have had problems with the energy-recovery technology so far in 2011 aboard the otherwise-impressive RB7 car.

Red Bull vowed to get to the bottom of the issue in the three week gap between China and Turkey.

“Our KERS system is fine, over the Easter break we have made some modifications,” Austrian Marko told the German newspaper Bild.

It was believed the main problem was overheating.

“It is much better now,” added Marko. “It works.”

Championship leader Sebastian Vettel, although losing to McLaren’s Lewis Hamilton in China three weeks ago, is confident not only for Turkey but also Barcelona two weeks later.

“The next two tracks should be good for us,” the German is quoted as saying by Kleine Zeitung.
