I was able to get around this issue by removing the carrier from the car. Made it dead easy.
I'm a big fan of UUC's had one in my E34 and now its absolutely amazing in my 128i. I have never tried B&M, but I am so impressed with how good UUC are I don't plan on changing.
I still haven't done the CDV mod I'm still debating this. But I'm very happy with how it performs now.
