DANIEL Ricciardo will face a five-place penalty for the Sunday's Brazilian Grand Prix after his Red Bull team has replaced the turbocharger on his car's engine.
Stewards said the sixth new turbocharger exceeded the rider's allowed ration, triggering automatic relegation for the penultimate race of the Formula One season.
Team boss Christian Horner said the problem was a consequence of leaving Ricciardo at the previous race in Mexico and the use of a fire extinguisher by the local marshals.
"You can not really blame her, the car obviously smoked," Horner Sky said.
"But they foamed the exhaust and when he froze in the turbo he ended it.
"He will take a penalty of five places, but hopefully on such a track it will not be such a big penalty."
Ricciardo was the first to leave the garages in Interlagos on Friday and wait several minutes at the end of the pit until the session began.
According to the F1 rules, penalties are imposed on the network according to the sequence of crimes recorded by the vehicle's transponder when leaving the pit lane.
This means that anyone else who raises a penalty will have it applied to Ricciardo.
The 29-year-old, who joins Renault next season, started the previous race in Mexico in pole position, before retiring for the eighth time, twice as much as his team-mate Max Verstappen.
A disappointed Ricciardo later said that he had not seen the meaning of the last two races, but soon changed his mind.
"I was angry and upset, at the time I felt that I was serious, but deep inside I did not do it," he told Sky.
"It was a great way to express how I felt.
"Fortunately, I wake up on Monday morning and it's like a new day and I can forget about Sunday pretty quickly."
Sunday's race has no bearing on the constructors' championship for Red Bull, who can not overtake Ferrari in second place or lose in third. The driver title was won for the fifth time by Mercedes Lewis Hamilton.
Mercedes put on Friday the second training pace before, Valtteri Bottas was only just faster than team-mate Hamilton.
The Red Bulls of Ricciardo and Max Verstappen were fourth and fifth.
Pietro Fittipaldi, 22-year-old grandson of two-time Brazilian Formula One World Champion Emerson, will be the official test driver for Haas next year, the US team said on Friday.
The Miami-born Brazilian will take part in a Pirelli tire test in Abu Dhabi on 27 November.
