Are the twin-turbochargers in Audi's 4.0L V8 engine starved of oil? An investigation has been opened into dozens of complaints about the engines being difficult to start or suddenly shutting down due to turbocharger problems.

  • Audi released a service bulletin that said the turbocharger problems are very rarely the result of a problem with the turbochargers themselves.
  • Oil starvation happens because an oil screen, deep in the valley of the engine, can become clogged and stop supplying the turbochargers any oil.
  • The vehicles being investigated are the 2013-2016 A8, 2013-2016 S6, 2013-2016 S7, 2013-2016 S8, 2013-2016 RS7
