Subaru Impreza WRX secondary air pump

Hello dear Subaru friends, my brother owns a Subaru Impreza WRX 2.5 with 230hp built in 2006. Recently he went into business with the car. At the turnoff he noticed that something was still going on in the engine room.The part ran until the battery was empty. After we gave the car start assistance, the check engine went on warning light. We then immediately drove to the friendly Subaru dealer. It turned out that the secondary air pump d 11000€ I wanted to ask if it is not possible to disconnect the pump and to bridge it with a resistance. If this is not possible, I wanted to ask if you know a page where Subaru spare parts is running, since I did not find it on the Internet. I hope you can help me further Thank you
