Mercedes and BMW aren't what they used to be when it comes to reliability while Audi has gotten much better in recent years. Audi's 4.2 V8 and transmission are nearly bulletproof and there are ton's of daily driver D3 A8's approaching 200k miles or have surpassed it with no issues, oil leaks, electronic problems etc. Nothing but regular wear and tear items.
MB is almost always the first to develop new and important systems for cars. The W221 had several industry firsts, just like previous generations of S-class models. But then the Japanese reverse develop the systems for their cars and make them more reliable. Even American and Korean cars are now almost as reliable as the Japanese.

I'm going to buy an infrared thermometer($11 at walmart), so no star needed for this.

If it comes down to it I would very much appreciate you offer. I finally got the OBD2 tool, so lets see what can be done with what I currently have.
Thanks again.

a little quote for ya from an actual MB Tech who knows what he's talking about

He needs to stop spending money on parts and equipment for his nearly dead 9 year old wreck and let a real mechanic with the right tools diagnose it so he can get a good idea on how much money it's going to take to make the car right. He can then decide whether it's worth spending the money to fix all of the broken issues, or dump it or part it out before diving into all of body and frame work.
I think spending $500 on a proper diagnosis would be money well spent before he breaks anything else trying to torque on it himself without the proper knowledge of how everything works. He's confusing this car with a 1970 Chevy.
The Best of Mercedes & AMG
Front battery(starter battery):
Off:12v
On(with headlights on aswell):12.5-12.8v
Rear battery(Brand new accessory Batt.)
Off:10.54v(This is after a turning off the car and restrting it 20 seconds later)
On(with headlights):9.24v
Do I need a new alternator? This maybe what my Battery light means/Why my comand shuts off thinking the engine is off(goes into safe mode)/Why my speedo flickers when the engine struggles..

I am not selling this car. I'm not going to a pro to figure out if "its worth me keeping". I'll take it to a pro if need be to figure out what problems I have that I was not able to figure out.

Please note that the car is highly reliant on proper voltages. Once you sort that out you may find that it addresses most, if not all of your issues.
Just to be clear, the battery you just put in the trunk should be a fresh (Recent manf date) fully charged (12.8v or so) by an AGM charger. A non AGM charger can easily damage or fail to charge an AGM battery. Your car will not charge the accessory battery at 10.4V, it will just indicate a failed battery.
It is a bad idea to change the transmission fluid at this time. You would be adding another variable to your current issues. Sort out the voltage/ battery issue first. Then move on to the transmission fluid change once you've settled the electrical issue.
From a site about batteries:
Digital Voltmeters should read as the voltage is shown in this document. The sealed AGM and Gel-Cell battery voltage (full charged) will be slightly higher in the 12.8 to 12.9 ranges. If you have voltage readings in the 10.5 volts range on a charged battery, that typically indicates a shorted cell. - See more at: https://www.batterystuff.com/kb/arti....YJKY0cDF.dpuf

Steps:
1.) have the front/primary battery tested. I will give a 95% probability that it is your problem.
2.) Have the car scanned with a Benz computer,
3.) Off to the rack
Get the tranny serviced before you put any miles on the car... but only AFTER everything else is fixed.

A battery at 10.x volts is absolutely dead.
Didn't you just buy this?
Also, if your voltage drops when its running, you likely have an alternator problem.
Like these gentlemen said though, proper voltage is absolutely key here. Don't do anything else until you have a good battery.
