Whining noise on turn

[kbj149]

Hi all,

I've uploaded a video to illustrate: http://tinypic.com/r/2w5sfon/7

Whenever I've taken her out for an hour and given it maximum beans, I experience a whining noise when turning the wheel. Its apparent when driving but cant be heard as well because of the engine note, however when stationary it can be heard when rocking left to right.

Again, only happens if I've thrashed it, pootling to work and back each day and theres no problem or sound whatsoever.

I'm thinking power steering, possibly?

Thanks in advance.

Sounds like air in the power steering pump, have you checked the level?

Used to have a 530d that had a similar problem, but more of a whining grind than a pure whine. I found out at MOT time that the steering rack had a weep and over time it would loose power steering fluid resulting in the unpleasant noise. A quick top-up of power steering fluid saw the noise instantly disappear. It turns out that the power steering system was very sensitive to fluid level.......so I'd recommend checking out you PS levels, topping up as required and then looking for any weeps and seeps.

Oh, and the Beemer ended up needing a new steering rack.

Hhmm, just checked pipe leading from the PAS reservoir and its very sticky. I'm going to undue the jubilee clip tomorrow and check for any splits or if its perished, looks like the culprit and therefore losing fluid.

Thanks both for your input.

I have the same problem, a leak from the PAS pipe work just below the pump. Notorious for leaks.
It will make things noisy when you turn the wheel,and on idle. I checked mine tonight and started the car up and I have the same problem. Its going into the garage this week as I cannot get at the jubilee clips from above, needs to be on a ramp.
