Bernie Ecclestone says he would not rule out Dietrich Mateschitz following through on his threat to walk away from Formula One.
Red Bull's 2014 Championship got off to a dismal start in Australia where Sebastian Vettel retired while Daniel Ricciardo was disqualified for exceeding the fuel flow limit.
Red Bull, however, insist his RB10 was within the limits and that the issue lies with the FIA's fuel flow sensors.
The team's appeal will be heard on 14 April.
Mateschitz, though, is not happy with the situation with the Red Bull owner warning that his participation in F1 has limits.
"The fact is that the federation's sensor has given inaccurate values since the beginning of the (winter) tests," the 69-year-old told Kurier. "We can prove that we were within the limits [in Australia].
"The question is not so much about whether it makes economic sense, but more to do with the sporting value, political influence and the like.
"We have had it all but on these things from our perspective there is a clear limit to what we can accept."
And Ecclestone reckons Formula One should not take Mateschitz's threat lightly as the Austrian billionaire is also unhappy with the new look and sound of Formula One.
Asked about Red Bull's possible exit, Ecclestone told AAP: "I wouldn't bet my money he won't leave the sport.
"He's rich enough and powerful enough to make his own decisions."
