Should I Replace Turbo Pressure Control Valve at 70K Miles?

"Hello, I have a 2019 Mercedes-AMG GT 63 S (M177 engine) with 70,000 miles. The car is currently undergoing preventative maintenance. Could you please confirm the correct part number for the turbocharger boost pressure control valve (wastegate solenoid)? Is A 008 153 54 28 the correct part number? Also, is this the correct shape (see attached image)?

Even though I’m not seeing any fault codes or symptoms, would you recommend replacing this part proactively to ensure long-term reliability? I want to make sure the car stays in optimal condition.

I know nothing about this part, or if this is typically replaced, but sounds like it would have gotten a workout up until now. On the other side of the coin, this is a proven part, don't know if a new one will do as well. If it were me, and the price were right, I would talk myself into replacing for piece of mind.

I guess you should only replace it when you experience symptoms and/or you hear that classic honking/goose sound.
