Another suspension fault with normal height only warning
Ok i am now completely out of ideas of what to do and could do with some help if possible.
2005 Discovery 3 2.7 SE.
So I get the fault when trying to change ride height, up or down.
I have replaced compressor, air storage tank, front sensors, front valve block, brake light switch, battery and relays. There are no visible or audible air leaks.
If I allow all the air out of the system and start the car I can hear the compressor and it raises to normal height with no issues and no errors, If i leave the car for a few days there is no sagging or loss of ride height.
If I try off road height the back will raise and the front tries for a moment and then the fault appears, same if i try access height, the back lowers but front will not and i get the error, any help would be appreciated.
I check error codes and these are:
Fault 1 - RLM (Ride Level Control Module)
C1A32-01 Intermittent - Right front corner valve
U0421-94 Temporary - Invalid data sent from ride level control module.
U0132 - 87 Intermittent - List communication with ride height module
HELP NEEDED PLEASE
Regards Steve

I know you say the front valve block has been replaced but it does seem like that is the problem still. I would check to see it there is any old desiccant in the valve block as the old compressor may have left some in the air lines

Many thanks for the reply, I will have a look at the pipes and valve block again, I just found it strange that there were no issues when going from empty air tank to normal ride height, could it be that I have not yet done a calibration after replacing valve block and sensors?

Sensors? You mean hight sensors? If so, yes you could get all sorts of issues if they're not calibrated.Richard

Thanks, I'll calibrate them and see if that sorts things out
