Photos and a write-up for replacing the compressor bypass valve diaphragm and spring. Something I recently did as I took things apart to check my turbo for boost problems. Like I mention in the write-up, I am not sure how often the CBV diaphragm or spring goes bad (Tech???) and I don't know if it's necessary to replace them as preventive type maintenance but if you plan on doing this job I hope this helps out.
A method for bypassing excessively compressed intake air in a turbo-charged engine system comprising determining, by a throttle valve position sensor that a throttle valve has been suddenly closed wherein said determining is performed by analyzing a value of time derivatives of an electric signal (voltage) generated from the throttle valve position sensor and bypassing excessively compressed intake air from an intake manifold to a air intake before said compressed intake air reaches a compressor of a turbo-charged engine system.
