This is very frustrating! I have a 2003 E320. I have ps fluid being slung by the drive belt. I have replaced the pump using a new o-ring on the reservoir. I just now finished replacing the main pressure hose from the pump to the rack because that was leaking up near the pump. Still have steering fluid slinging! The return hoses to and from the cooler to the reservoir look ok. Has anybody run into this? Also while I'm at it, my remote only works using infrared at the door handle. Not sure if key transmitter is bad or possibly the antenna in the car. Hate to spend $250 for a new remote if that's not the problem.

 

You might be able to test your remote at your local auto parts store; there ought to be an RF detector right next to where they sell remote batteries.
