Not sure but I think there may be a software fix for that.

Has your OBDII diagnostic scanner been able to clear codes before? If you're unsure, bring it by a MINI indy shop and they can clear the codes for you for a small fee. You have have BMW specific codes that require a BMW specific scanner to clear them.

Also, why did you replace the cat and O2 sensor in the first place? Did you have codes that pointed to them as the issue for your SES light?

I used the Shark purchased here to reset the code and restore to stock - light went off. Came back on on second start ... code is 2096

Use a smoke machine to fill the exhaust system with smoke and look for leakage, I have only seen exhaust leaks cause this fault. Now knowing that you've replaced the cat and O2's I would start looking for a lean condition, check fuel trims are they indicating a lean condition? Double check all your exhaust connections and if you find the fuel trims are indicating a lean condition check intake system for leaks especially around the supercharger air inlet. Check Fuel pressure.

Depending on the MINI FC code, you could have a too lean condition. Assuming what code you posted is P2096. As Casey said, perform a smoke test. A local indy shop can do this for you.
