You need to reset the codes and see if they come back,
The mapsensor fault may mean it needs to go back to autronic to fix it but you need to reset to see if its just a small issue,
If you have a loose wire and the ecu turns of and on with the engine still turning is will bring a baro/mapsensor fault. the overboost at the same time could be just a overboost or a ecu swithcing off on boost then reseting the baro and then it will see a overboost if you then go back on boost,
The cranksensor issuse can be caused by a misfire on the 36-1 trigger being more sensative to picking up misfires and showing them as a fault,
Or it could be a back cranksensor/camsensor fault you need to reset these and see if it comes back before a misifre causes it,
To reset these go to ecu error history and press R on the keyboard this willl clear them then go out and test and then recheck or have the laptop live while drive and see if/when it comes back.
