whats wrong with my bmw?

i had an auto electrician out and he plugged his computer in and loads of codes came up mainly abs sensors,left and right wheel sensors etc..is this a common fault and should i get them looked at or replaced? he has reset it all and cars running fine but its obvious it will happen again at some stage..
thanks again

does the engine rev and run ok? any warning lights on dash. did the clonk sound come from the gear box is it an auto box? have you checked the fluid level recently, does it look contaminated, when was the fluid last changed. what mileage has the car done. just some ideas.
