Sounds like you have a boost leak somewhere downstream of the turbo

I have seen the " Check DV " Code loads of times. Check for leaks and test the DV for VAC leak but its worth giving the MAF a clean too as a dirty or old MAF could give the same code. You could log the output too. (The two engine faults are linked so cure one and the other will clear too)

The Haldex code is a bit of a worry. Have a look at the wiring to the controller and the controller itself. Is it possible its got wet lately?

If you can't find any issues or breaks in the wiring, it could be an internal fault and will need replacing I think.
