An audit by a company called Capgemini has found "discrepancies" in relation to Red Bull's budget in the context of last year's resource restriction agreement.
That is the claim of Italian magazine Autosprint, as Red Bull's Sebastian Vettel travels to Singapore where he can wrap up his second consecutive championship this weekend.
Earlier this year, boss Christian Horner denied claims the team flouted the FOTA-governed cost savings agreement by as much as EUR 60 million in 2010.
Autosprint said the suspicion is that Red Bull broke the agreement by filing contentious information about its structure and workforce.
The magazine cited "sources" in claiming Red Bull figures have attempted to stop the Capgemini audit because it is an "invasion of privacy" requiring the release of "sensitive data".
The report said the teams association FOTA, headed by McLaren's Martin Whitmarsh, wants a "clarification" at a meeting this week even though "at the moment there is no mention of any penalties".
Autosprint also questioned the timing of the emergence of the Capgemini story, given that Red Bull is on the cusp of securing both the drivers' and constructors' world championships for the second season running.
