Check the 12v after the car has been in sleep mode with out waking it up. You should see the voltage come up when the car wakes. How old is the 12v?

Sorry for the delay in noticing my reply to your question did not post.Check the 12v after the car has been in sleep mode with out waking it up. You should see the voltage come up when the car wakes. How old is the 12v?
Honestly don’t think nitrogen vs air would’ve made any difference with that wild of a swing along with being in that frigid env for a week. If you want to refill with nitrogen, that should be easy as even Costco tire fill up stations offer nitrogen.Question for those that have replaced the pump themselves: has anyone then gone and had the system purged and refilled with nitrogen? I have just replaced the pump on my 2013 MS. I live on the west coast (warm, high humidity) and travel to visit family in the depths of the Canadian prairies (brutal winter cold). In fact that exact trip is what killed my previous pump: I went from +10°C (+50°F) to -28°C (-20°F) and then spent a week at that frigid temperature. I've owned the car since new and have made that trip a bunch of times, this wasn't the car's first exposure to that kind of swing.
The nitrogen by itself likely won't make any difference but bottled nitrogen is dry versus the ambient air in my climate which is humid. After I put the new pump on the system filled itself with ambient humid air. The service manual procedure for pressurizing the EAS in my era of car involves fiddling with Toolbox. If someone has indeed filled their suspension system anywhere else other than Tesla I would love to hear about how that went. My closest Tesla service centre is a 2 hour drive away.Honestly don’t think nitrogen vs air would’ve made any difference with that wild of a swing along with being in that frigid env for a week.

Yup. I didn't make that clear - it's not the cold by itself that broke my old pump, it was that my old system had a buildup of moist air from my climate and the cold+water is what did me in. Now that I've put the new pump on myself, the system refilled itself using ambient air and so is back to being full of moist air . I don't seem to have any leaks, my scientific test was to leave the car in my garage for 2 days and it didn't seem to settle.Cold itself is not bad, it's just if there is any moisture it will freeze in the compressor and eventually break it.
Use N2 if you can, add CRC AIR break antifreeze in the tank, just a little bit a cup more or less.Question for those that have replaced the pump themselves: has anyone then gone and had the system purged and refilled with nitrogen?
