CLK 350 W209 fault codes

[such01]

My neighbours CLK 350 W209 with the M272 engine had a CEL yesterday with a loss of power. I did the neighbourly thing and scanned with IcarsoftMB2.
There were many faults, mainly related to low voltage which I put down to when the battery was low and I used a portable starter to start it. I cleared all these and rescanned.
The CEL remains off but the following codes reappeared:
P2004 Tumble flap intake manifold stuck in actuated position - This would appear to be a broken intake manifold air lever, which I've checked online
P0355 Ignition coil of cylinder 5 open circuit
P0305 Misfiring of cylinder 5
P0352 Control line to the Ignition coil of cylinder 2 open circuit / ignition coil primary current is too high.

Am I correct in thinking the lever for the intake manifold requires replacement with 2 ignition coils for cylinders 2 & 5? Perhaps the wiring to the coils are faulty?
Or could one fault be causing the other?

Thanks

I've just done some live data readings and have the following:
622 IM pressure 330mbar
623 IM pressure ADC 1.31 V
340 IM Changeover SHORT
B28/10 Right IMTumble flap position sensor 0.14 V
B28/9 Left IM Tumble flap position sensor 0.09 V

0 fault counters on all 6 cylinders
619 B37 Pedal value sensor Voltage 1 0.3 V
620 B37 PVS Voltage 2 0.15 V
626 M16/6 throttle valve actuator voltage 0.62 V
627 M16/6 tva voltage 4.37 V

I'll ask my neighbour to take the car for a drive to see what happens and rescan, but are these readings consistent with the 1st fault P2004 broken IM lever?
I cannot see anything indicating faulty coils in the live readings
