Power Steering Pump problems of the 2006 Mercedes Benz M Class

I have same problem with my car and my model is not effected with this recall recall number: 05v224000 dates manufactured: Jan 0001 to Jan 0001 number of vehicles affected: 7191 date owners notified Jan 0001 on certain passenger vehicles, a hose clamp that secures the power steering fluid cooling hose to the power steering fluid cooler may not provide sufficient clamping force for this connection. Consequence of defect: a loss of power steering fluid can damage the power steering pump and may result in diminished power assist for steering which could lead to a crash. Corrective action: dealers will replace the power steering hose clamp free of charge. The recall began on may 17, 2005. Owners may contact mercedes-benz at 1-800-367.

The steering pump was damaged by a leak. I previously brought the car in complaining there was a loud whirring noise. I was told the problem was resolved. Then this problem began again, I found there was a recall on the NHTSA website. Brought the car back to the dealer and was denied repair or that there was any recall that existed. The recall number is 05v224000.
