1. 1Confirm the fuel-system recalls (18V323000 ECU/fuel-pump software, 18V473000 fuel-level sensor, 19V513000 high-pressure fuel pump attachment) are closed on any specific VIN.
2. 2Confirm the transmission wiring-harness recall (19V883000) is closed; the damage risk could shift the transmission to neutral and cause a loss of propulsion.
3. 3The S63 is direct-injected; intake-valve carbon buildup is the normal long-term maintenance item for this engine family (shared with the X5 M / X6 M and M8), not a defect.
