No Start Help - 2010 E63
Car is a 2010 and has 68k. Main battery is 5 months old. OEM Auxiliary Battery replaced two weeks ago.
Went to go run errands this morning and the car wouldn't start. In fact the horn sounded for a bit and then denied any sort of start procedure. All lighting and interior electronics work fine. I even hear a start click, or relay click that you would normally hear just before a startup, but in this case, nothing happens after that click.
I checked the battery, its fine at 100% power via my battery charger. I even unplugged the battery and still the same problem.
I wont be able to scan the car, or try and jump it, until this evening when my roommate brings over his generic OBDII scanner and truck. I am currently awaiting calls back from my MB service writer and my independent technician facility.
Thoughts? Any things to check? I checked the "Starter" fuses in the engine bay, and they all seemed to be fine. I am a little weary that this may be related to a bad ignition module of some sort, something I guess the W204 cars have issues with from my quick research online.
Any input or help on this would be greatly appreciated. I head overseas on Tuesday and would like to get this resolved before then, without having to tow the car to the dealer if at all possible.

With that said, Im towing the car to my Indy tomorrow.
Anyone know how to release the shifter so I can put the car into reverse?
Here is my findings on the CPS, and CAS.

This is a common problem with the W204 cars, and all mercedes share the same system.

I'll know more tomorrow. Appreciate everyones input. Wont be ordering anything until diagnosis is done.

Generic scanner is throwing the following codes.
P1614 - Electronic Control Unit Reset / Recovery Occured
P2158 - Vehicle Speed Sensor B
P0607 - Control Module Performance

OP, I saw the video and could hear the engine turning over which probably implies it's not the starter to a large degree. Normally a crankshaft sensor can be diagnosed by pulling out a coilpack & connecting it to a spark plug + then turning the ignition key. If you see/hear sparks at the plug tip, then the crank sensor is ok. I dunno, on a lot of cars that I know of, the crank sensor governs the spark. I'm guessing the camshaft sensors work in the same way if they have failed too.
That being said, I'm pretty sure a quick scan on Xentry will pull up which sensor has failed.
I wish i knew how to get the car into neutral. If you find out, please share with us.

P1614 is Control module voltage error
P2158 can also be caused by faulty pcm (or no/low voltage to it)
those 3 errors together seem to be pointing to voltage issue or ecu issue
as for putting into neutral this worked on my c63 M156 but not sure if same for your e63 M156

I dont believe you can put the car in neutral. Merc has an adapter that attaches to the rear hub, like a bearing, so that the car can be rolled around.

Thanks for al the input on those codes. You are in Delray right? Do you have a good tech or service writer there I could call and discuss this with? I heard they are much better than Mercedes North Palm up by me, which I have used in the past and was not that happy with.

as for neutral i still think the same unlocking mechanism is under the shifter assembly ... i will see if i can find the diagram (edit: i think there's a flap just under the "P" on the gear selector. You insert an object like the end of a ball point pen in it and push down and that allows the gear selector to be taken out of Park.
