Going to replace mine this weekend with the GFB’s DV+ unit. What's the consensus on 2wd sedan, need to drain water pump to replace or can it be worked around?

Need to drain coolant and remove water pump.

Some Will get "Blow-off Valve stuck/Shut" But this is a easily cleared tuner code. Either constantly clear it or leave it until you can get it coded out. DV+ you have to drain and remove water pump like OP said.

Every body keeps saying you HAVE to drain and remove water pump. Not the case, I opted out because I recently changed expansion tank and was tired of dealing with coolant. It's possible without with ball end hex sockets, a tiny craftsman bit holder and turbo piping out.

Okay... You Don't Have To remove it if you don't want to. Its personal preference. But to keep from peeking with one eye and your tongue out while your wiggling extensions. Why not remove the pump and flush the coolant ( if you've never done a flush it'll be good for the car) Once again this is my personal opinion and you can do whatever your heart desires.

Depends of your car. Good luck doing it on a xDrive without removing the water pump. Draining coolant is a very optional step, but not doing it is just cutting corners and augmenting the risk of receiving coolant in your eyes when working. It's a simple step and doesn't take lots of time, while it saves you time and makes the job a lot easier.
