The engine swap is not related to Lewis’ FP2 power loss issue. His system has been returned to Mercedes High Performance Powertrains at Brixworth for further examination.
Mercedes reported that the issue was related fo abnormal oil pressure, but the details would be diagnosed at Brixworth.

As we already reported the power unit in question was the oldest one that Lewis was using, and taking into account this was a previously planned swap, it seems the unit was never meant to be used in qualifying and the race.
Mercedes also installed new gearboxes for both drivers.
Additionally, Mercedes advised all of their customer teams to switch to the power unit with the least amount of running, as a precaution due to Hamilton’s issue.
