Ok so just bought a 08 range rover sport hse from auction. I had to replace the front air stut due to leaking bag and was getting the red suspension fault 30 mph and dropped all the air. So replaced the bag and hear no leaks now but after replacing the bag im getting a yellow suspension fault normal height only. Before the fault comes on i can hear the compressor running constantly it shuts off for a few seconds then back on, once i get the fault message the compressor shuts off. When the compressor is running it sounds fine. I cant hear any leaks anywear or any strange noises from compressor. Any ideas what this might be? If the drier in the compressor was bad would it cause these symptoms?
