Jeremy Clarkson has been accused of "fabricating" the danger he was in during his recent trip to Argentina.
The crew had to leave the country after a Porsche with a number plate which appeared to reference the Falklands War angered locals.
It was reported they feared they were going to be stoned to death.
But Argentina's UK ambassador Alicia Castro claimed Clarkson had "fabricated an exaggerated story".
A car used by Top Gear with a number plate apparently referring to the Falklands War is a "very unfortunate coincidence", the BBC claim.
The Porsche, driven by Jeremy Clarkson for a special episode in South America, had the registration number H982 FKL.
The number plate sparked anger in Argentina and the cast and crew of the show were forced to flee the country after being attacked with stones by protesters.
A BBC spokesman said: "We're pleased the team is safe and would like to thank all of those who have helped. As the executive producer has made clear, the number plate issue is a very unfortunate coincidence."
The executive producer of the motoring show, Andy Wilman, earlier said suggestions the number plate was chosen deliberately were "completely untrue".
Footage appears to show the moment protesters throw stones and hurl abuse at the presenters of Top Gear for "mocking" the Falklands War.
The Top Gear team faced angry protests after using a number plate that appeared to reference the Falklands War.
