If it's any consolation, mine does the same thing. My local dealership replaced the entire SC but it didn't fix it and then said the sound is normal at start-up. It does go away after a few minutes once the engine is warmed up. I'll have them check again in a few months once my car is due for its next service.

Most likely one of the injectors.

Update in case it helps people- by chance during a service I discovered the garage putting their stock 0w40 oil instead of the JLR certified Castrol 0w20. I played hell and they changed the oil to the recommended type; to my surprise the engine went quiet, could not believe it.
In short the engine design appears very sensitive to oil.
