The FIA announced on Tuesday night that its Compliance Department had opened an investigation into potential breaches of the governing body's regulations.
While not naming Susie and Toto Wolff directly, a statement declared that an F1 team principal and member of FOM personnel were to be investigated following a media report.
"The FIA is aware of media speculation centred on the allegation of information of a confidential nature being passed to an F1 team principal from a member of FOM personnel. The FIA Compliance Department is looking into the matter,” said the statement.
This action had been prompted by a report in BusinessF1 magazine alleging that team principals were unhappy that Mercedes boss Toto Wolff had been privy to secret information from FOM.
With it understood that complaints had been made to the FIA, president Mohammed Ben Sulayem took the decision to take the matter further.
But any suggestions of wrongdoing by Wolff and FOM has been robustly denied by F1, which runs the F1 Academy series.
In a strongly worded statement, which made reference to the fact that it had not been notified of the investigation prior to the media statement, it defended both Wolff and its own reputation.
