Hi
You have not posted the code descriptions so I cant tell much. Do you need these descriptions or did you just not bother to post them? What have you checked?
I am at home so dont have access to info now. From memory your P1470 can be set by either an overboost situation or a wiring fault between the ECU and the MAP. P0100 is a MAF code and P1189 I think is the intake shut off motor. These two codes can be linked and can be caused by a bad MAF. Check the wiring between these and the ECU.
