Hi guys. Narrowed down rattle noise to the disa unit. It would rattle under load during mid-range acceleration and on start up. Unplugging the electrical connector stopped the rattle whilst driving immediately.
So will be getting it out this week.
I have had an m57n diesel with swirl flaps and from my understanding it's virtually the same flap system.

I followed a guide where a guy cut the swirl flap spindle with a dremel tool and he plugged the hole left behind with a screw and some thread locking compound. So in effect leaving the housing of the swirlflaps in the manifold but just removing the moving part. I did this on my previous car with success and not having to shell out £50 for blanking plates.

I would like to know if this is something I could do with the disa unit? Has anyone tried it? I've done a search and most results are people completely deleting the disa and hoses etc.
