You can buy them from Napa Auto parts for around 75.00.....they have a great warranty also. Do you know were to look for the battery, we had a hard time finding the thing to replace it. It was under the back seat. Just thought I would add that.
Unfortunately from a Dealer. It comes as the whole cover assembly and sells for roughly $109. Sorry

To replace the EGR valve in a 2000 Mercedes E320, first, disconnect the battery and remove any surrounding components for access, including the engine cover and intake hoses. Unplug the electrical connector and remove the bolts securing the EGR valve to the engine. Clean the mounting surface, install the new EGR valve with a new gasket, and reassemble all components. Finally, reconnect the battery and check for proper operation.

To change the battery in your 1999 Mercedes-Benz E320 keyless remote, first, locate the small slot or notch along the edge of the remote. Use a flat tool, like a small screwdriver, to gently pry open the remote casing. Once open, remove the old battery, noting its orientation, and replace it with a new CR2025 or CR2032 battery. Finally, snap the remote back together and test it to ensure it works properly.

alternator or bad wires
Remove the battery and have it tested at any auto parts store.

Test battery with a load tester. If battery passes you have a problem with connections or cables.
