A/C system has gurgling water sound--can it be fixed on 1998 BMW 740i

Research has indicated this is common problem and is solved by rerouting drain line. How hard is this to do and what routing is recommended? DIY selfer task?

there is a re routing process from bmw but i doubt you would want to try it unless you have access to a lift. they have relocated the drain as to limit expose that allow the drain to clog with debris
