The faulty engine which robbed Lewis Hamilton of victory at the Malaysian Grand Prix has arrived back in England, as Mercedes desperately attempt to resolve the mechanical problems which have derailed his Formula One title defence.
Hamilton was on course to win in Malaysia and take back control of the championship before his engine blew up with only 15 laps remaining.
It's his third engine failure this year, while his Mercedes team-mate and sole title rival, Nico Rosberg, has yet to have any major mechanical dramas.
Mercedes boss Toto Wolff says they'll leave no stone unturned to check the engines for the next races.
