Air suspension fault

Hi well here I am with my new L322 vogue 2003 project.
Thought with all my learning in the P38 it would be a doddle but its all different. To the P38 a whole new learning.

The air suspension button wouldn't work connected up friends LAUNCH test equipment. Cleared air suspension faults and switch lit up and had some action at the front of the car. Could hear air leak from passenger front side initially both drivers front and rear wouldn't work. After some fiddling got both front to rise. But back wouldn't rise properly. Then air suspension failed again with fault code. '' too much energy needed to inflate right hand rear airbag "
Is this due to the front leak. ? Do they pump up in a particular order ?
How do you check the air hose to the airspring for leaks without taking airspring out ?

Sorry fault said not enough energy to inflate right side rear airspring

Rear first then front, this is to stop dazzling others when the headlights are on!

Could be a flecked rear spring or a weak compressor!

How do you test for a faulty airspring without taking it off the car first

Soapy water!

Fix the leak before burning out your compressor !!
