Cybertruck Cyberbeast Air suspension... how does it operate?

[James Cole]

Hello guys...

Just got a 26 CB, and wondering how is the air suspension supposed to work... I hear the air pump always on for 3-5 min after any startup...

I checked pressures on service mode and basically what it does in that 3-5 min it fills the reservoir around 10 bar or more, but next time I use the truck the be 24 hours or 40 minutes the reservoir it at around 1 bar... so it loses everything and starts the whole cycle again.

Truck has sat for couple days without use and the suspension never sags...

Wondering if this is normal, took it to Tesla and they said its working as designed...

Here are some pics, one with the reservoir filled and the other one is 40 minutes later after using the truck again, reservoir went to 10.4 to 1.1 Bar

Could you guys check if yours behaves the same?

Yeah, you have a leak. My reservoir is at 17.6 bar after sitting on the charger (disables suspension adjustment) for over 4 hours.

I concur. I'm at 18.5 bar after being parked for more than 12 hours.

Never hear the compressor on start up, agree with the others

Not on startup maybe 1/8 of a mile later

Couldn’t get to “measure pressure and unlock gateway”

This is the screen when I got into my truck after parked for few hours:

just press measure pressure and follow the steps to unlock gateway… very easy.

That's what I did after tapping the measure pressure.

BTW, is mine bad at only 1.6?

Gallery pressure is different than reservoir pressure.

Gallery is the valve body, reservoir is the source tank. To measure the different points in the system, the valves to each gets opened, then the gallery pressure is read.
Did you get this report?

In this case, one of the fronts was read last, so the gallery is the same as that. (I was deflating corners, thus the low height and reading).
