I have had this issue and fault code C1 A13 64 for a while but believe that I have cracked it.
After trying several remedies I purchased a replacement inlet/exhaust silencer from LR part no LR018300, it cost £60.00 inc. It was a pig to replace getting the pipes routed through the anti roll bar and around the chassis but finally did it. The fault has not returned and we have just come back from a 2000 mile adventure up the west coast of Scotland towing our caravan with the car fully loaded and without any issues.
I have since cut open the old silencer and guess what, the 2 no sponge filters were full of white dust! the same dust removed from the 3 no valve units which were refurbished using a kit from 4x4 Airseals, which cured the suspension sinking over night issues. The air dryer has also been refurbished and the crystals replaced.
Hopefully this might help others with the same problem.
Attached a few photos to show the findings.
