RB is totally right, it is a DYI job with Arnott airbags... should not take you too much time... no need to visit dealer for the parts, labor or to clear message - parts are from Arnott, your own labor and message should clear on its own, unless there are other issues with suspension, such as the pump... savings of couple grand...
should not drive too much, or too fast - think about a twisted ankle... you would not want to play rugby or football... but you still can limp around the house, to get yourself a glass of water...
