The code I’m getting is accumulator pressure remains constant. I had that when I purchased the car and did bagpipesandys seal kit on the compressor which fixed that. Fast forward a year later and I stared getting same message. It’s been coming about once a month now. Ride height doesn’t change regardless of how long it sits. Trying To decide whether to do the seal kit again or try a new compressor out. I changed the front springs this summer so I’m guessing that could have weakened my pump
