The meanings for those codes are as follows
DTC P0557 Brake Booster Pressure Sensor Circuit Low Voltage
so it's a brake vacuum issue

DTC P003A 00 Turbocharger Vane Position Not Learned
exactly what was changed around the turbo ? it sounds as though there is still a problem there somewhere

Circuit/System Description
The engine control module (ECM) performs the turbocharger learn procedure automatically when the enabling criteria have been met.
After each ignition cycle, and before the enable criteria have been met, the ECM will use the previously learned value.
If the ECM does not have a previously learned value, it will default to a stored calibrated value.
The ECM commands the turbocharger vane control actuator to position the turbocharger vanes and a turbocharger vane position sensor monitors the actual position of the vanes.
During the Turbocharger Learn, the ECM commands the vanes to 0%, then to 100%, while comparing the actual and desired turbocharger vane position values.
If the difference between the values is greater than or less than a calibrated threshold, the automatic learn fails.
The Turbocharger Learn can detect sticking vanes, sticking vane position control actuator, or position sensor errors

Thank you valerie, I have it booked in at a specialist, Auto electronics. Its August 9th as they are very busy. This will help I'm sure.
As for the Turbo, it was just old out new in as far as I know. Thanks again. Praying it's not the ECU.
