If it's the pulsation dampener it's not steering related but suspension related. It's on and active all the time the engine is running. I've discovered myself that the sound travel from the engine bay of a W215 is a bit weird, the sound doesn't move in predictable ways and what you hear from the front may be coming from the back.
If your pulsation dampener is under the driver's side wing you may well be hearing it from behind the firewall bulkhead. Certainly there's only a few things that can whine. Is it the ABC pump itself, does it sound a bit like a knackered turbo?
That is true and so hard to detect, if it had failed I presume that it could still have some effect otherwise no point in having one.
