E320CDI (W211) error codes: 2530-002, 2526-002, 2527-002, 2376-001

Hello,
I have a W211 with V6 320CDI (642920) and the last week the car went to limp mode. Checked the error codes and the stardiag show these codes:
- 2530-002 M55 (inlet port shut off motor) short to ground
- 2526-002 test signal cable to component Y77/1 (charge pressure positioner) short to ground
- 2527-002 Y27/9 (left EGR) short to ground
- 2376-001 Check component N3/9 (CDI control unit). Control M16/6 (throttle valve adjuster) Voltage too low

Have you ever encountered this error? Do you have any advice or tips on what should be checked or possibly replaced to eliminate the error?

Any advice would be gratefully received, thank you.

Inlet shut off (swirl flap) actuator motor has failed due to oil spill of the turbo seals, and it blows fuse.

AKA swirl flaps

10pence to fix... middle two pins on the swirl flap motor multiplug - find the connector down beside the fuel filter, fit a 4.7k metal film resistor then swap the fuse - you might find it drives better
