I had the same issues as posted above however I had a leaking air bag. I replaced my front airbags with arnott bags and I just ordered the compressor and rear bags as well to be set! so excited to have a flawless suspension! took it to a local foreign auto, awesome work for 1/2 the price. BMW dealership would want 5k for a complete rehaul of the suspension I paid 2k a lot but well worth it for the 4.8is!
