Thanks for asking your question. I will try and help you out.

Code 25 is defined as a boost pressure sensor fault. I have seen this many times. Most often the problem is a failed boost pressure sensor. It could also be damaged wiring harness that connects to the sensor. I would inspect it first. If the harness is OK. I would replace the boost pressure sensor.

Please reply back if you need more help or have more questions. I am happy to assist.
