A British newspaper report claims Formula One's governing body was made aware last year of allegations that Renault had fixed the Singapore Grand Prix by ordering Brazilian driver Nelson Piquet Junior to crash.
The Daily Mirror quotes the driver's father and namesake, also a triple world champion, telling investigators that he had spoken informally to FIA race director Charlie Whiting at the season-ending Brazilian race in November.
Former champions Renault will face the FIA's world motor sport council in Paris on Monday to answer charges of fraudulent behaviour that could see them kicked out of the championship or fined heavily.
Team boss Flavio Briatore and his engineering head Pat Symonds have already left the team and Renault have said they would not contest the charges.
