    I installed a BSH N18 OCC on my 2012 Clubman S a few weeks ago. I'm not new to modding cars or turning wrenches and had a BSH OCC installed on my last R56S N14. The issues I am having is that both fittings from the valve cover and turbo to air box tube keep either blowing off or loosening up. I have done searches and have not turned up much. Any suggestions of remedying this? I have reached out to BSH thru phone calls, email, Facebook message, and even posted a comment on their Facebook page. I even broke down and posted on the "other" forum.

    I have one on my 2014 C-Man and did notice it's just a slip fit in the one hose but have not had it blow off yet. I'll be following your thread just in case.

    It seems to be fine for a few days and then either fitting pops off and the Clubman runs really rough. The last time the check engine light came on for a vacuum leak.

    Could it engine movement (torque), causing the hoses to pull off the fittings on the OCC?

    That is a theory but its not the hoses but the actual fittings.
