It keeps me wondering what BMW ist thinking...
They introduced the PPK for the N54 with software and hardware.
They then introduced the PPK2 for the N55 with software and hardware.
Only months later they introduced the PPK1 with just software...
Is this because the N55 handles the heat better...? But why did they deliver the PPK2 with a water cooler instead of a oil cooler in the first case...
