On the plus side, I've never heard an N54 that didn't rattle, so it is really weird to just hear the engine now, even on decel. Time to put everything on + flex fuel.
I can confirm this. I too had turbo actuators, all injectors, and coils replaced at the same time, under warranty (work done @37K). This work required upgrading the car's software which made the car lethargic. Placed the Vishnu V5 back in, proof, back to normal plus more.
