SL320 Power steering

[abbtim]

Have had a small leak from the power steering pump, which was fixed by dealer but I am now getting a whine when car is cold or nearly on full lock. Does this mean the fluid is low or is there something more serious?

The power steering does make a noise on full lock,its the relief vave opening

Yes, but this should not happen on half lock, or it never used to and I have had 8 different Mercs over the years, none made this noise. I am sure that this new noise is not normal. Have had the car for thirteen months and it has only just started to happen. I initially put it down to the cold weather but now it is warmer is still happening

Ok,that is different, I think that you will have to go back to the dealer, what did they do to fix the leak ?

Mine started making a noise when the fluid was a bit low. A top up stopped the noise. Check your reservoir just in case.

If the fluid is fine then I'd check the steering damper - a fairly common failure item and easily replaced yourself for £30.

Checked the reservoir this afternoon and it's only just on the bottom of the dipstick so I think that must be the problem. Thanks for the advice.
