Help!! Bmw scanner 1.4

[vthoma11]

Hello forum I am in need of help. I have an 2002 X5 4.4 with four corner air ride. I have been having issues with it for for two months and have been taking it to the dealer every two weeks. Every time I go they charge me a diagnostic fee even though the issue has not been corrected. First it was a sensor or so they claimed then it went to being a valve unit pressure accumulator and cracked my head to replace it. once it was replaced it still read a fault code and then they said the pump was pumping 13psi below normal. I replaced this myself this time and my question is i have BMW scanner 1.4 can i use this to erase the fault code and see if it would reset the system to avoid giving the dealer anymore money.
