bmw 328 ci coupe 2000 w reg, my battery went dead for my fault, jumped the car with jumpleads, started straight up, but now my power steering does not work and you cant hear the power steering noise and can only just about turn steering wheel, i want to know is there a fuse or relay that runs it that i can look at before i look at the pump, i have checked the fuses in glovebox but they are all ok, are there any more fuses to try ????, thankyou in advance
