All warning lights came on do not put in gear car just stopped in the middle of road
I don't know what happened I was driving everything was fine I went to make a right-hand turn and then the middle of the turn the car turns off and it says do not switch gears except I'm stuck out in the middle of the road I can't get the car into neutral.. I can't give it to turn on it says it's not in park I can't get it to go into Park

I Cant get it to turn over.it wont change gearsS. The esp sos battery and visit workshop without changing gears keep switching and a loud fan turns on. W
the ISM often fails... this gives the message go to workshop, don't shift gears…
what it means is the mechanism to select gears has died and if you play, you might be unable to get back in to drive to get home...
it should say "don't turn off, leave in Drive, and immediately get it on a ramp at a workshop to swap out the ISM (intelligent servo module) - or you may become stranded"
yours sounds really great - you'll have to get in neutral or P to get it to crank.... and in doing so might end up stuck (but ur already stuck), if it doesn't play ball its pick up the car on low loader and if stuck in P, get it out, or disconnect prop shaft (you must never tow an auto without taking prop off !!! )
The dead car will roll in gear enough for you to push it off the road. The engine is de-coupled from the transmission via the torque converter. After it's safe, put a new battery in it and start diagnosing the charging system.

Well the police didnt give me much choice on moving the mother ******. They inpounded it because mercedes road side assistance never showed up, nor triple a, or my insurance. Got it at inpound took it to a German auto place.. I know I know it needs to go to dealer but I live 100 ****ing miles from one. Sorry not cursing at you.. the place the car is at now says it won't even talk to the diagnostics computer.. lucky me. I bought it 4 months ago introve at home from the dealership in Atlanta 120 miles to my house.. had dinner. Went out to go to the post office in it and book got to drop 6 grand on the transmission.
I mean I really think I should sue Mercedes this was un****ing real being stuck out in the middle of the road unable to move the car. If I had been a very busy intersection. I could have been killed. This electronic gear shifter bull**** on the ****ing steering wheel. Is just that. Im sorry. I need a break. Ill be back when im calmer
the ISM wont communicate if its dead... its a normal failure about $400, its bolts on the outside of the box, if the place doesn't know this they must never have worked on a Mercedes?
I still think you have a low voltage issue. The car is fine, the ISM is fine, everything is fine. You have a dead battery/charging system malfunction-not a big deal. Your mechanic is trying to upsell you. You still never gave us car specs.

We charged both of the batteries it still says take to dealership. I think we are just going to sell it. I do not want to be in that super dangerous situation again. Screw mercedes this just goes to show they do not make cars to last anymore. Buy a new one and dump it the day the warranty is up. Mercedes is now a scam. I have loved every mercedes ive ever had but screw them now. The car is at the house. The tow company destroyed the front fender. I give up. I do not want a car that every time something goes wrong with that you have to have the ****ing software. Ridiculous

The ISM (intelligent servo module) is responsible for the transmission gear position it can prevent the car from starting if it does not recognize that it is in Park, mounted @ side of transmission housing.
I had this message twice. First I just restarted and went away. Second time did not even start or shift.
you could be able to start the vehicle if you pull fuse out. But you wont be able to shift. I called Hydraulic truck to tow my car. Mechanic advised to replace and program to my vehicle a (continental) brand ISM. From a used car 2010-2013.
your sitution not only ism light, but so many.Check what happened for example battery ...etc

Iam sure your car is pre face lift 2006-2009. It is a common issue with this ism. Check ebay or aliexpress you will find w221 ISMs for sale more than windshield wipers.
Well the car .. I swear I'm about to take it out into a field and put a grenade in and just see what happens. I have to wait till the 27th before I can even take it to the shop.. so today I decided to check all the fuses.. I checked them all locked to the car went inside and cooked dinner. I came back outside to get something out of my car.. and the key would not unlock the door by pressing the buttons.. so I used the blade, it worked on the trunk but not the car door. I think Jesus is testing me. It's got to be something electrical because if you turn the key and it says do not change gear take to dealership and you play with the little gear selector all the lights dim and brighten up and darken... The trunk release would work but the motor would not close the trunk.. a loud fan comes on.. and and i noticed when I'm trying to lock it. A weird motor sound happens that I had never heard before towards the front driver side of the vehicle. Normally the shocks make all kind of noise of it leveling itself.. I used to be a die-hard Mercedes fan this car has changed that completely.
Dude, I started the video, and literally pulled my headphones off (ATH-M50x), paused the video and jumped up to peek out my front door because I thought that was MY CAT outside in a standoff with one of the hood cats.
Back to the subject at hand, you're hilarious! And yes, I think Jesus is testing you, Lol. All laughing aside, like I said in the beginning, you have a voltage issue. It's probably the easiest, cheapest thing you could check yourself, without tools even, but you haven't reported back on that. Until we get a voltage/battery SOC status, I'm just not sure where to go from here. If you had Xentry, that'd be a different story, but obviously we're working with no tools so far.
Edit: Sorry, the above was a response to the OP, which I presumed was you, under a different account. Unless it is you? Anyway, check voltage, BOTH of you Lol

Reason: OP?
So evidently I left the key in ignition with it on accessory overnight and that's probably why the key buttons didn't work. I'm charging the battery right now but is there a way to get to the engine battery without being able to get in the car? I can only get into the trunk for some reason the key like the actual metal key works on the trunk and the glove box but not the door so that means somewhere in there that door's been changed out or someone changed out the locks which I thought only Mercedes qualified locksmiths are allowed to touch the locks or whatever.. so that means the Carfax was lying. I wonder if the car will open after I charge the battery in the trunk. . I'll try to get the voltage to you tomorrow.
About 3 weeks ago my rear cigarette lighters weren't working and I checked the fuse and it was blown so I changed it but it still didn't work so I found the relay and just went to AutoZone and bought I assumed the same relay... Could that have messed something up? I know Mercedes is very finicky on things like light bulbs and buying a cheap generic part.

It was I have two phones and I can never remember which account I logged in on so I just picked a new one I guess LOL. But I've had a w126, a w124, a w211 wagon that was stolen and this is the replacement for the stolen vehicle. I loved my w126 into this day I'm still pissed my ex made me trade it in.. I loved to my w-211 as well.. the 124 had the bad wiring in it, so that one while beautiful and a coupe 1995 320 coupe, which is rare, oh and it wouldn't go in reverse which I did not know when I bought it because surprisingly when people bring your car out for you to test drive they leave it on and you don't think about it. So now every time I test drive a car make sure every gear works.

It is a preface lift but one of the previous owners have had the tail lights changed out to the refreshed version. It's surprising to me that that car cost $100,000 in 2007 and it doesn't have a backup camera ..I mean really?.

I did download the Mercedes star xentry software (illegally) off of a torrent from the dark web but I can't figure out how to install it
I dunno man. Sounds like there's all kinds of stuff going on.
Soo. With the batteries unattached to the car they both sit at 10.5... with the batteries attached to the car the front battery sits at 10.4 unfortunately I cannot turn the car on.. the back one however sits at 8.5.
