Landrover Range Sport L320 suspension fault

Hello all dear members!

I have a suspension problem with my car. Flash the red supsension fault lamp in the dashboard, and the fault code is C1A00-54.
I upload photo about the 4x4 menu.
Please help me what is the problem.

Best Regards, Krisztian

Hi @csohkrisztian , do you have a diagnostic tool that can check the sensor voltage and heights for the standard setting.
Is the compressor running at any point?

yes, i have diagnostic tools.
This is the realtime data. The compressor is running but, sometimes have a message “the raising slowly” and if it shuts down then it starts up again with a slight twist.

(Raising slowly) will probably mean the compressor is a bit worn and struggling to make enough air.

I understand you, when i lower the car the level is not good... and when the raising in finish, it's not good either. I dont understand, and the 4x4 info screen its not correct.

Above my pay grade them.

You mey need to check the pump output, without knowing what it should be.. I can't be more helpful sorry my friend.
@Saint.V8 could shed some light with specifics.

What's not correct? You have a fault, most likely with the compressor, so until the fault is fixed, the screen won't necessarily be right.

As above....it looks like the compressor is working too hard due to either a leak or the compressor is worn.

It is reading a low tank pressure...my first thing would be to remove the compressor and bench test it and see if it is capab le of creating pressure.

From what I know the temp sensors are 0-5v...so with it reading upper 4's the system will shutdown to prevent overheat damage...that being said, the reading of 58 in the compressor temp section would suggest it is warm but not above the usual shutdown threshold which Ithink is in the 120's....but that maybe the P38 threshold.

Rising slowly faults indicate the system is not seeing the expected height change in a set amount of time, again, this points to a compressor fault or a leak.

I saw the pressure sensor at 3.6 but I don't know enough on this model and didn't want to point our op in the wrong direction.
What's the normal operating pressure on the system?

Thanks for all.

Compressor is working fine. The pressure is 3,8. I starting a height calibration, but i dont understand. My english is not so strong.
I have this error message :
