Had same misfires on E60 N52 engine because of lambda sensors that did not throw any error. Check the values , doesn't matter if the engine si cold or hot, the BMW lambda sensors have 4 wires and they work all the time regardless of engine/exhaust temperature.

Believe it or not, i had one pre-cat lambda with stupid values (it was not dead, just giving bad values) and the car ran like the engine was totally wrecked: rattling, smoke, bad misfires (sometimes i couldn't even accelerate to reach the parking) - all happening at high RPM. I did like you, before checking values: changed cam cover, coils, plugs, vanos solenoids and nothing changed until i replaced the faulty lambda sensors.
