I have a new to me 2012 R56S. I have done one oil and filter change. The coolant tank is very difficult to pull up and out of the way. It seems like the connecting hoses are far shorter than earlier versions that I have seen videos of. Is there an easy way to get at the oil filter housing? Someone suggested removing the fluid from the expansion tank, removing the expansion tank completely to make it easier to get at the filter housing. My fear there is I don't want to cause any cooling problems by doing that. I'm not against pulling the tank if it makes getting to the filter housing easier. Any tips?
