I need to move this mercedes I use it for spares and can't afford to buy it new keys. I have removed the ignition, hoping that I could Please say it's possible
This doesn't give you the answer you were looking for, but I'll post it here in case it gives you a desirable end result.
They don't make it as easy as on other vehicles, but you can shift it into neutral without starting it. This was on a C240, but should be the same or similar case for you https://www.youtube.com/watch?v=MB4p-G5uXyo Basically, pull off the bezel around the shifter, lift a little black tab on the bottom, and you can then shift it as needed (e.g. neutral).
You can't just put an automatic into neutral otherwise it would have been done.
You most certainly can if you defeat the shifter interlock, as @atraudes suggests.
Or get under it and move the manual valve and get the parking pawl out manually, If it's a wreck you can chock it and leave it in neutral.
Or better yet, throw a chain around the front suspension and drag it out with a pickup. Might break the parking pawl (bonus!) but I doubt it.
