How to fill Jeep air suspension with compressor air (airmass too low)

So I’ve had this problem a couple times this year and when you repair air suspension on a newer jeep you are supposed to fill it with nitrous.
However, the tool needed is very expensive and not even all dealers have the tool. If you try to fill it with air it will say airmass too low and won’t allow to use the air suspension, the suspension requires 200 psi give or take and normal air compressors can’t supply that.
So I’ve figured out a way to get the cars built in compressor to fill the air suspension to required psi, by filling reservoir with air compressor to 120 psi you can fill entire suspension, all you’re supplying is air mass, the car will pump it to required psi this way.
Tools required are an air compressor, blow gun, and a cheap r134a quick connect fill hose for small cans of refrigerant.
Hope this helps someone out

You don't need a compressor to fill the nitrogen reservoir tank. If you have a nitrogen cylinder and a scan tool, the pressure from the nitrogen cylinder is more than enough to properly charge the system. It needs exactly 175 psi as per the shop manual. Filling it with air is a very bad idea. The moisture in air will freeze up in subfreezing temps, causing the system to malfunction. That's why the system is filled with high purity nitrogen......it has no moisture in it to freeze up.

This is a GREAT idea if your system is empty and you need pressure to chase leaks.

So what can happen if you use just air? If it freezes, what's going to happen to the system?

Wich its de name of that connector??

Awesome, thanks for the video. It's exactly what I needed. Have you had anyone come back with a failed pump due to using regular Air vs the Nitrogen? My dealer wants $360 (richmond Va.) just to fill it. I think air should be fine since Mercedes uses the same system and they fill from atmosphere.

Nope, no problems. Harbor freight also sells a compressor that goes to 210 psi for 200$, you can buy and return it. I’ve filled a few like this.

In case you were wondering, you’re gonna want to set it to approx 180 psi if you have a higher pressure compressor. If you have a smaller one you can just fill it this way, then set ride height. Make sure you replace all those little brass fittings you can buy them on Amazon for whatever you replace: they tend to fail one after another

@@SLAutoRepair Thanks for the Help! I'm tackling it today.

Don't use air if you get freezing temperatures where you live.

What kind of nitrogen?

[@JuanMartinez-cw2hs]

I don’t have a the scanner I need to fill up the nitrogen tank. I don’t have a scammer & can’t move the Jeep it’s down to the tires & the setting to jack the car up is on.
