5 Series E60 520d (N47) SAL
The VTG control unit has an integrated regulator for emergency running mode. The regulator provides
redundancy for controlling the multi-plate clutch in the DSC control units.
The regulator is used to attempt to maintain all-wheel drive for as long as possible when the DSC control unit
malfunctions or important sensor signals drop out.
Substitute values are calculated when individual sensor signals drop out. Functions are operated by using the
substitute values until it is no longer possible to control the all-wheel drive effectively. This can lead to the
complete loss of all-wheel drive.
