Adaptive Suspension height is fixed, there is no raising lowering, it's simply 10mm less in height than normal suspension.
The whining is the LPFP priming the main HPFP fuel pump to prevent long turnovers when starting. As others have said, that became apparent after a software upgrade when HPFP issues were common. |
