I've never experienced this. Friends 92 300D 2.5 (that I sold her ) behaves as if it has zero power steering for the first 10-20 seconds of running. Then it works fine and does everything it should. Never acts up while its driving.

I put 1000+ miles on the car when I had it with no issues, never had checked the level.

When she began to experience issues I checked the level for the first time in my ownership. Spot on where it should be.

Turned the wheel lock-to-lock to try to bleed the system. Level didn't drop, and the car still mis-behaves after sitting a while.

I do not know much about power steering systems. Could this be indicative of the pump going bad? Is there a check valve somewhere that is bleeding off pressure when the car is sitting?

Insights are appreciated.
