W212 Turbo Actuator
This car had light on and faults for DPF clogged (Fill Factor of 400%) and Intake Air Leak.

I cleaned the DPF and reset DPF adaptions.
Test drove and the codes did not come back.

However, when driven hard I felt loss of power and limp mode.
When tested I got the following code:

P024872 Output 2 for the low-pressure turbocharger has a malfunction. The actuator does not close.

I had to return the car without further testing.

This has the sequential twin turbo with vaccum actuation. Is it likely to be the pressure transducer or should I be looking at actual turbo issue? It is family members car but I get very little time to check it as he is always driving!

Attached is the Quick Test with Freeze Frame Data.
