Get the bypass valve here: http://amzn.to/2mDbFoi - Step by step mechanic's eye view of diagnosing/replacing a bad supercharger cutoff valve on a first generation MINI Cooper S. A bad cutoff valve (BPV) can cause loss of power and in some cases OBD codes such as P1689, P0301 and P1237. Loss of power most apparent around 2800-3000RPM as the engine transitions from non-boost to boost operation, then power comes back as you go to full throttle.
