E70 3.0i Water Pump Differences

[lt2mc]

Hey All, Just looking for some information. I am in the process of replacing my water pump and T-stat. I have both parts out of the vehicle, and I am waiting for the parts, eta 08/25. I am aware that there are two different part numbers for the water pump, one for vehicles with adaptive drive and 4 zone climate control, the other part number for non-optioned vehicles.

My question is, what are the differences between the two types of pumps and will I be able top tell the differences when the parts are side by side?
Thanks in advance.

BTW the removal process was very slow, but not outrageusly technical. Hopefully removal is over half the work.
