Last week i had an error light come on saying" found fault with suspension". This locked the switch and the light in the switch stayed on. I got home and when i went out again all was ok it moved up and down and lights and errors all off. We park the car and lower it every time we get out and found that if i do that the error light come back on but if i leave it at ride hight then it acts as normal and no error messages appear .But i have noticed that the rear o/s goes down ,first time over night then it takes 2 days to go down now. I have just started the car and run the hight settings to max and back to norm then to low and all works as should. Did this about 4 times and all went ok . So i guess that i have a small leak other that Compressor ,sensors , can anyone say what it would be from my description THANKS FOR ANY HELP

Partially blocked filter on compressor or lazy compressor - LR has now upgraded component and changed supplier.
