CBV Replacement
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.

Say what? Please.

I found this sitting on my parts shelf and don't need it anymore. It is the Viva Performance "CBV upgrade kit" that I bought directly from Viva for my 850 but their website lists it should work on any turbo in the TD04 family. Please check your fitment before buying. It is new, never installed. Took it out of the box to look at it and that was it, went right back into the box.
