the 240D you had a while back didn't have one im pretty sure. Mine doesn't. Didn't you drive that thing over the winter? I can't recall. I doubt this is a major issue realistically.

Unless you plan on installing a light bar, busting out your state trooper badge, and camping out on 95 with the engine running, I don't think you will need it. Besides, if you DO decide you need it, easy install later. Might as well wait and see if the 200 bucks stings

Mine I have no problem with no aux pump in cold temps, and ive had several cars where the aux pump was bypassed for functional issues with no cold weather complaints.
