Mercedes team principal Toto Wolff was reluctant to share any information when quizzed about becoming consultants to troubled engine supplier Honda.
Fernando Alonso's MCL32 required yet another power unit change at the Circuit de Catalunya, prompting questions about whether there was any truth to the rumours that Mercedes were prepared to act as advisors to help out Honda.
"No comment," said Wolff when initially asked about a potential relationship with Honda.
But Wolff was pushed again later on in the FIA press conference to give a more open answer to the question.
He reluctantly added: "We are not doing anything for Honda, that is the current status quo.
"So unless that situation changes, I don't want to contribute to rumours out there that are false and I think are damaging for Honda, and create hard standpoints from teams or other stakeholders. We will see what happens."
