None of my friends not with this type of transmission. I will review the simulations of other transmissions.

Guys - just have a look. Really - this transmission does what an auto does just a little crude & more simple with all the actuation etc. external.

I do not understand why we are not getting any fault codes?? 
The trouble is that none of us know this gearbox well but it is an electromechanical device at the end of the day - it cannot be that difficult. Have you ever had a CEL?
This is where dealers have an advantage - they can try things. Can you borrow an ESM from a friend & try it? Do you know anybody with a Sequentronic?
Karo,
Star allows you to run a simulation with most things like this which could help us find a sticking solenoid etc. (eg. you can run a simulation on 722.6 or 722.9 if I remember correctly) - Can you have a look for us.
I think I am going to have to buy a Star!! - only trouble is then my driveway would be full of friend's Mercs.
Good luck all. We will learn from this exercise. If it stored just one fault code from the list you posted above it would give us an idea of where to look.

You can run a simulation on anything. What do you want me to look up? A sticking solenoid? (My lack of knowledge doesn't let me understand the question)
But he wasn't able to get into the ESM which is the main key here. If DAS can not communicate with ESM then there should be a problem with it

That's what I am not understanding, there are fault codes for nearly anything maybe if even the owner farts in the car it'll throw a fault code so I'm surprised why vakity isn't getting any.

That's why I wanted to try another ESM - to eliminate it as the problem. I know they are expensive so I was hoping we could borrow one to try.
I even thought it might be an idea to try a simple OBDII scanner that reads the transmission range of codes - I did not suggest this as I can't understand how an OBDII scanner could read something the Star can't
We all have our strengths & weaknesses here. I know the mechanical side well. You & John are the Star boffins. I've used Star but on general crap that has been easily sorted out.
Please don't apologise!! we need your help & you are one of the people that shares your knowledge openly.

Yes Karo - I want him to simulate all the normal fuctions the GB goes through & see if it hangs up on one of them. If Star can't communicate with the ESM we are in crap & need to overcome this.

On transmissions 716.6 i can't find ESM, therefore, STAR, can not connect.
So I think

Let start fresh, bare with me because my ADD makes my mind jump in all places.
So your main problem is the car doesn't go into reverse?
If this is the case did you check the reverse lamp switch? Also did the problem happen right after you changed speed sensor or did it work and later it stopped?
Thanks

Yes but after several attempts from N to R - failed. And then, N to 1 or Auto - also declined. Now no switches, nothing, only Neutral. When the engine is running. We will shoot pictures show.
No problem with reverse lamp switch.
Тhe problem happen before I change the speed sensor, I changed it because the oil flowed from it. Although oil flowed from it I'm not sure that was damaged.

I can not understand why when I start Learning process for gears, stops here.
Nowhere do I find something to write about it.
This did not understand. By looking parameters, writes that it is wrong, or I do not understand what they mean or do not know ...
All this is simply impossible

I don't get it as well. It says process fault code but there are no fault codes. I'm very confused on this as well. By looking at the fault codes it should atleast throw something but doesn't. I wonder if you unplug battery over night maybe it might help? I don't really know.
Ed, who had the 722.6 coupe had similar problem. It would not shift and key was stuck. He unplugged his ESM and took off battery and it started working again. You're right that your transmission might not have ESM but you have to have similar module where you can unplug and see if it resets.

I will first do all the tests, of guided tests: as in Star
Then, I will do what you say. With battery and with this module.
Karo, Glyn M Ruck, Благодаря братя!

Picture is DAS simulation. Before you weren't using simulation were you?

Do exactly what I did now. Competed tension and resistance, just as written in STAR. And guess what, everything is normal and is OK ... Jump fall, may not be true .. I did all the tests and everything is ok ..... Now remove the battery and the module ... And I will wait ... How you propose to wait?

Leave disconnected overnight so that all capacitors discharge completely.
Don't get mixed up with terminology - it does not matter. Lets call that thing under the passenger kickplate the TCU (transmission control unit) as we would with an auto. It fulfills the same function.
I'm pleased everything checks out but I'm worried about that "Process current fault code" That means it must be throwing a code but we can't access it.
Let's try disconnecting battery & TCU - reconnect tomorrow & see what happens.
If we still have trouble making it relearn then let's try & get hold of an OBDII scanner & see if that can read the code.
Karo - just so I understand. With the Sequentronic you say we can't do a total software flash. We have to take the TCU through this step by step learning process - am I understanding you properly? It kind of makes sense with this sort of tranny.

I'll wait until tomorrow to see. I'm order OBDII scanner and wait for it to arrive. Coming as I'll try it.
Scanned with Carsoft again and no errors found.
tomorrow if nothing happens, I begin to think about any mechanical problem I do not know anymore.
I'm not sure but I think in development mode, you can flash ... But do not dare to touch there. as discover some interesting things here, but in German, and almost do not understand - I would need a dictionary

Sweetness!
I am using, Mercedes Benz Star C3 version 03/2010 with developer mode.
Is installed on usb hard drive on a virtual machine without a network and do not know if it is possible to be released.
Yes I did a quick scan without any errors except that I am not synchronized panoramic ceiling. And the actual transmission, there is no error. I'll check Control Unit Version.

Karo,
Where did you get this?
Carsoft reads errors but doesn't define them.
I have pulled my hair out trying to find lists of error codes, such
as ESP codes. I had a wheel sensor go bad, and had to pay to get it read.
Sensor was only 80 and easy fix.
But I got a 'deal' w/ my indy mechanic and only paid $300 to replace the sensor, which I'm sure was
an easy fix. Problem was I couldn't read it out. Of course it occurred to me later to just buy one front and one rear and try replacing them
till I got the right one.
But then, in this thread there's mention of a learning procedure for wheel sensors?
Is it possible to get a complete list of error codes for all modules on CL203? say, uh 2002?
Sorry for going slightly off-topic but I have begged so many times for lists like the one you attached with no
love.

Yes - I can speak Afrikaans/Flemish/Dutch but my German is terrible.Please make sure that the scanner you buy can read transmission codes.
I use an Equus Innova 3130
See this & scroll down to table.

Some scanners don't read transmission codes.
See you got your Air conditioning workin - so it was the fan in the overhead console.

To do a totall software flash you will need to go into Xentry Flash in DAS and you can flash it from there (but this requires a username password and might not work with cracked ones). Or you can order the disk (software of the transmission) and do an offline flash.
The way were doing it isn't a total flash, just setting overwrite you can say.
