Hi,

My discovery 3 is coming up with a suspension light fault sometimes. Sometimes everything seems to work fine and sometimes it won't allow me to raise or lower the suspension and or access the various terrain modes.

I ran a diagnostic and got the following error codes
C1A20-64 Permanent: Pressure increases too slow when filling reservoir
U0122-87 Intermittent: Lost communication with vehicle dynamics control module.
C1A00-88 Permanent: Control Module
U0132-87 Permanent: Lost communication with ride level control module
U0155-87 Intermittent: Lost communication with instrument cluster control module.

I wondering what this could all mean, and the best approach to find out what the issue is?

Thanks
Paul

 

You should post in the D3 forum. Get more eyes on your message there.

 

Hey Paul, did you ever figure it out. I pretty much have the same fault codes. My LR3 backend suspension started to slowly drop while I was driving and the tires where rubbing against the frame. I ended up pulling the raise suspension switch and that temporarly fixed it but trying to figure out the issue and have a scanner.

Thanks

 

I ended up replacing the compressor, cleaning the compressor intake filter, replacing the reservoir valve block, and repairing a leak in the reservoir tank end bolt. Ie I had multiple leaking issues. It sounds like you might have a faulty rear valve block.

 

Thanks Paul for replying. I will check into the rear valve block.

Thanks again,

Bay
