your dealer is spot on johhny,because of the high oil level once the oil it gets hot it gets drawn up into the intake system via the crankcase breather system & enters the inlet manifold as oil mist(not unlike injected diesel) which starts to burn rapidly.whilst the diesel injection system injects a controlled metered amount of diesel fuel on each injection pulse,once the oil mist starts to burn you have no means of controlling the speed of the engine & if not stopped by stalling the engine it will rev to destruction !! this also used to happen on older style of diesel engines (non common rail) if there was a fault with the governor for example on the fuel pump this could allow the pump to keep injecting past the maximum governed speed of the engine & they just use to rev up until they blew up unless you managed to stall it.
diesel fuel itself has whats called a `rising characteristic` that is for a given amount of fuel the engine will rev up & up untill it blows up,thats why diesel engines are governed to prevent themselves from overevving & causing damage.
has your engine sustained any major damage ? if you managed to stall it & saved the engine from any major damage then by draining the oil back down to the correct level it may be ok !
