The Sepang paddock has been awash with rumours since yesterday that Ferrari's front wing will go under official FIA investigation.
Ferrari's rear wing drew attention in Bahrain, where it was cleared by the FIA, but now it's the front wing that is causing controversy.
Suggestions have been made by some of Ferrari's rivals that the upper element on the Italians' front wing moves at speed, and the illegal movement could be seen at close-up video.
An FIA spokesman told autosport.com there is no investigation at the moment, while a Ferrari spokesman added: "I don't want to comment on any rumour. If there is a problem, there is procedure through the FIA."
Paddock pundits suggest, however, that a formal protest would only be lodged after the race, and any investigation taking place - if at all - will have to wait until then.
