So I dont think it has anything to do with the air leaking out. I have had the vehicle stationary in the same spot without power for over 36hrs now with no change of the deck height which is very good news compared to before!
But the C119A came back when I had driven it for approx 10 minutes, this time with no CAN/comms erors, ONLY the C119A. C119A is not a warning since the light is stationary and has audible warning. It also disables the up/down keys in the back.
The owner manual advice to go direct to a service station, so it's a serious fault. Im just wondering what it could be???
