Boost leak troubleshooting?

Okay, I searched on this DTC but found nothing. I recently installed some EVOMS diverter valves and ran into some issues. The DME shows DTC P2281 although the diverters seem connected okay. I did notice putting them in that there was a fair amount of oil in the drivers side boost hoses. There was also oil residue all around the area behind the drivers side intercooler above the lower boost hose. The drivers side Bosch diverter did have the vacuum line disconnected when I went to replace the diverter valves so not sure if that caused the oil spray. What is the best way to check for a boost leak under that DTC? I attached an picture of the area where the oil residue was mostly located... passenger side was dry.
