BMWPower06

Hey guys, so on my way to work today, I took a turn rather hard and was trail braking around the turn(yes not the best thing, but I braked too late as the light had just turned red). Anyways, so I took the turn pretty sharp while braking. After that I immediately began to notice a very slight vibrating coming through the steering wheel while at idle and a weird noise coming from the engine, almost like a buzzing sound. The sound becomes more prevalent when turning the wheel or starting to accelerate...Does anyone know what the problem could be?

Thanks guys

check your power steering fluid. don't know where it is in the M5 engine bay, but it will have a cap that looks like a giant torx bit. if it's like my car with Active Steering, it requires Pentosin, CHS11, available from the dealer or NAPA. most other places don't stock it. If it requires it the fluid reservoir should say so.

Ok I'll go look for it in a bit. Does any1 know for sure where the reservoir can be found? And is this most likely what is wrong? My only issue is, is why did the noise start all of a sudden after the sharp turn?

found it and it is in fact low..weird thing is that i didn't hear the buzzing when I just went and started it up
