Red Bull has put the brakes on Michael Schumacher’s celebrations, after the seven time world champion on Sunday tasted podium champagne for the first time since 2006.
Mark Webber, who finished behind the Mercedes at Valencia, had radioed the pits - and therefore the listening FIA - to complain that Schumacher had deployed his overtaking rear wing ’DRS’ system through a yellow flag zone.
"I hate to dampen the euphoria about Michael Schumacher but it is clear to see on the television images," Red Bull’s Dr Helmut Marko said on German television Sky.
Team boss Christian Horner added on RTL: "The stewards have all the information and will take care of it."
A post-race penalty would surely cost Schumacher the podium.
But according to the BBC, Mercedes team boss Ross Brawn checked the data personally and found that Schumacher disengaged the DRS flap thirty metres before the yellow flag zone.
