Random fault codes
 

My parent's X5 has all these fault codes, (airbag, transmission, DSC, low oil, gearbox, service light, etc) come up on the instrument cluster randomly one after another. After going in and out of the dealership for over a month, the problem still persists. The SA said to have BMW NA engineer come out to inspect the car but found no problem.:confused:

I own an E46 M3 and spend most my time on m3f instead of here, so I have completely no idea what is going on with this X5. Anyone?
