The diagnostic equipment on these cars is too primitive to get any meaningful data out of and can throw false readings all the time (newer cars are much worse in the latter issue though). IMO on something this old its better to judge the condition of the parts by looking and listening to things. If its making an unusual noise or looks super worn/leaky, fix it.

Will his mechanic get much richer? He connected his super-duper BMW scanner, and it showed nothing.
