Hey folks

I recently started getting drivetrain malfunction error intermittently in my 2019 M550. I took in it into the dealership and they are saying the codes suggest that I need to replace the turbo charger wastegate valve actuator. The cost to do that is coming around $1800, are you guys aware of any service bulletins that extends warranty the warranty of these parts. I know that 530e has a SIB that covers this.
Otherwise can this be done at home ?
