new to this so not sure if this is correct 'place ' i have a 2013 520 estate ,rear suspension not right !! seems airbags were replaced by previous owner ...mechanic says module has been disconnected at some stage previous ... he hasnt repaired one before but is willing to remove it/try fix it but of course cannot be sure ..am told they are quite expensive though if need be bought ...also see some people replace air one with conventional shocks/springs ...really lost on all of this as to best/easiest,,,, least expensive solution ... thanking ye in advance !!
