Most likely an issue with the diverter valve (Dump valve) - may just be a sensor issue, or may be the actual valve.

Should be an easy fix but one for the dealers if its still under warranty (And Standard)

Not standard and we have changed both of the (dump values) and fault still pings up when you run diagnostic

What was the actual code?

The N249 solenoids control the dump valves, it may be an issue with the sensors that control them rather than the valves themselves.

Also N75 valve controls the turbo waste gates, may be an issue there. I would have hoped to see if any of those numbers were in the fault code somewhere to help detect the issue but that's where I'd be looking first.
