I can't understand where Renault have gone wrong. They had this engine on a dyno. Even the most unsophisticated dynos show up vibrations under load. If this 20 weeks is to be believed and it's vibration problem it must be the crank. I am guessing that the cranks are forged? So can it really take 20 weeks to redesign, have a die created, forge the crank and then machine it? I know creating the die is a very sophisticated job and I am guessing that Renault can't do that themselves. In fact they probably can't forge the crank themselves either.
I really am struggling to understand how this monumental balls up could happen!!!
