The big danger is you'll break the plastic pipe which will then necessitate removal of the intake manifold. That removal job has been described as one of the most hated tasks even by experienced e46 DIY'ers.

If indeed these are the squeeze tab types, best to try to get small needle nose pliers in there to break off the squeeze tab ring around the perimeter so they will not be holding the hose onto the plastic. You're not going to reuse the rubber hoses anyway. Then you'll be free to just wrestle off the hose. Your main goal is to preserve the plastic hose if at all possible.
Replaced the hose, went to the dealer to get it and I installed it just like you said. If you look at the photo, does it appear that the expansion tank is relatively close to the belt? Is my radiator out of place?
