On a 2003 Mercedes-Benz E320, the Power Steering reservoir is located in the engine bay, typically near the front of the engine on the driver's side. It is a translucent plastic container with a cap labeled for power steering fluid. You can identify it by looking for the hoses connected to the steering gear. Make sure to check the fluid level when the engine is off and cool.
The power steering reservoir on this vehicle is found under the hood of the car. It is usually found to the back of the engine, near the firewall, on the driver side of the car.
It's built into the power steering reservoir. To replace it you need to replace the whole reservoir. Fortunately, this is an inexpensive part... ($30).

The car should still be under warranty. Take it back to the dealer.
Open the engine hood and remove the black Mercedes Benz engine cover. It is the reservoir on the front right of the engine if looking from the front of the car. It is a black reservoir and cap. Check the fluid level and add accordingly. Note, this car does not take regular power steering fluid, but takes a pentosin hydraulic fluid. Also if your power steering fluid is really low, then you could have a leak. And its possible on your model that if you don't see any external fluid leaks, that it could be leaking internally in the steering rack boots. Just something to keep a eye on.
Probably on the pump itself. From the left side of the car look down below the alternator by the firewall.
Turn the wheel ALL the way to the right and then ALL the way to the left a few times. This will force air out of the lines. Top off the power steering reservoir when you are done.
