E320 CDI OM613 Boost Issues

[M.A.94]

So was on a little bit of a road test after doing my prop shaft flex discs and centre bearing yesterday. Car seemed perfect so I decided to give it some beans. Pulled like a train until eventually it went into limp mode. Came home plugged the diagnostic computer in and this is what I’m getting.

P1470 - 016
Charge pressure control Positive control variation. [Charge pressure is too low, ]

Any one got any ideas?
