Steering problem
1995 Mercedes Benz S500 V8 Two Wheel Drive Automatic 130000 miles

My benz has developed a noise problem when cold. The power steering pump whines and the steering is noisy when I turn the wheel back and forth. The noise stops when the engine heats up to normal temps. The routine is to heat up the engine, turn it off for 5 minutes and them turn it back on. The steering stops making noise and the whine in the pump stops.I changed the fluid and filter and the original return lines(2) but that didn't help. The fluid level doesn't drop or there does not seem to be anything leaking other than a little around the front seal. Help, help, even in South Carolina it gets cold in the winter.

Do you
have the same problem?

If I remember correctly, GM had a problem like that with a lot of their front wheel drive cars in the mid-90's.

They came up with putting a long stretch of cable inside the power steering pump hose to act as a dampener.

There was never a recall because it wasn't a safety issue, it just annoyed the drivers.

Was this
