So the new pump is in and everything seems to be working like it should. I won't have a chance to drive the X5 much until next week. The old pump was definitely louder and less consistent in sound than the new one. No notable difference in resistance between the new and old across the motor, both about 3.2-3.4 ohms measuring with the harbor freight DMM. That is a super easy install.
I will play around in the hidden menus next week too.
Nothing exciting in this video but here it is anyway.
