Must use Xentry or aftermarket equivalent to disable the SBC unit prior to service and then to reactivate it after service.
Failure to disable and de-pressurize the reservoir can result in 70 Bar (>1000 psi) or more pressure being vented into your face. When reactivating, ensure brake pads reseated on the discs *before* putting the car into gear and using the accelerator. Might take one or two activations using the brake pedal to ensure pads are firmly on the disc.
If in the USA, let the dealer do it. They even washed my car after the service.
