Hello Guys,

So every time I drive the car I get yellow triangle popping up on the screen with message "suspension fault". Error codes are as follows: U0421-81 State: Intermittent, "Invalid data received from ride level control module", C1A20-64 State: Intermittent "Pressure increases too slow when filling reservoir", C1131-92 State: permanent, "Air Supply". I have noticed that rear right side sits lower than the left side. I also have "vehicle too low" yellow warning when on idle and as soon as I start driving red triangle pops up with same message. I know it could be many things, but is there anywhere I can start? I don't want to buy new compressor in case it isn't that. Any help will be much appreciated.
