BMW Repair: code, reed switch, m52

Question
cant find info on code p01475 any help would be nice

Answer
without knowing the model of the vehicle,thats why I ask for the VIN as it helps diagnose different things.What I found with the code p1475 says it's "leakage diagnostic pump reed switch did not close" I have found it with th Z3 manual with M52 and S52 engine with Seimens DME.What does it mean? I cannot actually tell you I don't know.Is there a problem with the car? Can the light be reset?Hope I helped.
