Air Compressor output test

[pwacka8]

Hello All
Got the dreaded orange and yellow suspension lights on , fronts on the floor.

Took the car apart this morning and tested for leaks , cant find any, i have had the orange light on last week but the suspension stayed up.

Last week i read codes , air leak in system and no default level.

after my investigation today im getting no default level and lower limit reached.

Compressor runs when car is started then the lights come on and lift is greyed out on mmi.

The control block seems to be ok , as i was running output test through vcds i could here the different output air valves operating in turn as i was going through each step.

I suspect the compressor is knackered but i wanted to see if i could measure the output using vcds to see if its output is down.

I believe you can get the output pressure from the measuring blocks some how but im not sure.

Can anyone guide me as to where i can find its current output and also what should it be.

Many thanks in advance as allways.
