Need some help please .
I have been having boost problems which is bringing up 1106 (boost pressure) and sometimes 0100 (maf sensor voltage) .
I have since changed the BCS on the turbo, actuator and the map sensor, aswell as checking over vacum hoses including the black box underneath the block . This has brought no luck
The car doesnt have any power at all over 3,000RPM and boost is basically non existant .
Any ideas ?
