Reportedly, F1's chief executive and the French carmaker are having a dispute — ostensibly about Renault's motor home.
In Barcelona last weekend, Renault – supplier of engines to multiple F1 teams including world champions Red Bull – was told to park its motor home outside the paddock.
Ecclestone said: "Renault is a supplier, and if we let them all in the paddock, there would be no room for anyone else."
Auto Motor und Sport, however, claims the dispute runs deeper than that.
Reportedly, Ecclestone is pushing for Renault to reduce the price of its turbo V6 engine next year for customer teams, after naming the price at between EUR 20 and 23 million per team per season.
The customers are complaining, but Renault is apparently refusing to budge, leading to the motor home situation and Ecclestone's forthcoming meeting with Ghosn.
Meanwhile, Ecclestone said on Wednesday that he is unmoved by reports Munich prosecutors have filed charges against him over the Gerhard Gribkowsky bribery affair.
"They haven't told me, that's the only problem," he told PA Sport news agency.
"To be quite honest with you I haven't done anything about any of these things. I haven't bothered.
"If I have to get bothered, then I'll get bothered," the 82-year-old added.
