Looking at the engine, it's under the silver engine cover, about half way back.
Remove 2 screws on the cover, carefullly slide/pull the cover to the right until it releases from the lugs under the black cover.
Voila!
just like it is supposed to look.

Hello im having problems with my key getting stuck in the ignition barrel aswell and iv'e got a ML270 CDI all you do is 1. Press the brake pedal and make sure the cars automatic gear leaver is in the 'P' (parking) position. make sure that the key in the ignition barrel is not turned and try to select a different gear even with the foot brake on and it shouldn't move that means its activated a security lock which is normal.2. you start the car, 3. switch it off then 4. try and remove the key5. if it doesn't still come out just try and wriggle the key out (try all sorts of things like push the key in, try to pull it out while your turning it) ORalternativly with my car all i have to do is just take a spin around the block and try to take it out normally and it comes out easily. AND if all of this does't cure your problem then im afraid you will have to go to Mercedes Benz where they will see the problem further.
i have a 1999 ml320 so hopefully yours is the same battery set up as mine. after you take off top strap there is a bolt at the front side of the aluminum battery casing. remove this bolt, it takes a 1/2 inch socket with extension. you may also need to slide battery forward before you pull it. cheers
