CnAutotool.com share the Mercedes Vediamo Star diagnosis developer mode user manual as following.
MB Star Diagnosis Xentry Das with Vediamo Xentry/DAS Developer Mode

 
XENTRY MERCEDES DIAGNOSTIC SOFTWARE 2017 2 MB Star Diagnosis Xentry/DAS Developer Vediamo Mode User Manual
Here is MB Star Diagnosis Xentry/DAS Developer Mode User Manual, incl three part:
What you need for Mercedes Vediamo Xentry/DAS Developer Mode ?
When & why you should use Mercedes Vediamo Xentry Developer Mode?
How to use Mercedes Vediamo Developer Mode step by step?
THE MOST IMPORTANT NOTE: you are trying on your own risk!!!!!!!!
Be very careful when using the Developer functions! Many of them can cause irreversible damage to the components of the vehicle and may cause personal injury! Please be aware that modification to some specific systems (airbags, braking systems) may make the vehicle unsafe for on road use and may violate the local highway laws, rendering the car not roadworthy in the legal aspect.
This is especially true for the SRS modules, where unintentional usage of developer options may cause deployment of airbags/tensioners and other aggressive restraint systems.
IMPORTANT NOTE: what do you need for Xentry/DAS Developer Mode?
– original Mercedes diagnostic tools like Super mb star c3 or HQ clone like SDconnect C4 china clone mux
– DAS/XENTRY with good installation
– a laptop running with Windows XP better
IMPORTANT NOTE: why & when should you use Xentry/DAS Developer Mode?
As a presumed DAS user you have probably learned already that there are number of functions that would logically belong to the software options, but they
are missing from the regular DAS installations. These include recoding (variant coding) the control units without SCNs (Software Calibration Numbers), de/activation of commercially sensitive options (in-motion video of tv/dvd), recoding the configuration of airbag units, seat belt reminders, changing the configuration of instrument clusters, restoring damaged EEPROM contents for Comand/APS and other ECUs and many more. There is also an additional benefit: sometimes control units record a DTCs (error codes) that are filtered out by the production software. Developer kit allows unfiltered view on the module’s error memory, therefore allowing to see all stored trouble codes, including the masked ones.
The reasons for disabling these functions in the DAS setups seen at the dealership are very simple: firstly, risk associated with using them is too high to open these tools to (very often) under trained and rushing technicians; secondly, there are several legal obligations that put restrictions on what the dealer can do and what he can not – for instance, recoding tv-in-motion, airbags and emission-re lated systems fall into this category. Thirdly, electronically damaged components very often result in replacement, therefore repairing (recoding) would have adverse effect on spare parts revenue.
Here is how to : clean ASSYST Plus Memory
Firstly, you need the mentioned Developer key made according to your LAN ID. Before scrapping your old key, take note of the LAN ID (there are some cases when it changes ie. when reconfiguring the hardware) and the current License Key in the DAS. Both information can be found in the licensing menu of Star Utilities. Then replace your current key with Developer key, save and restart DAS. After selection of vehicle class there should be now a new screen (in German, except V-Series and W221 where it comes in English) informing you about dangers associated with using Developer Kit. You are good to go now.
In Mercedes Vediamo Developer mode : (tested version 11-2010)
Steuergerate (Control units) ->F3
Aufbau (Body) ->F3
ZGW (CGW) ->F3
Entwicklungen (Development data) ->F3
Steuergerate – Anpassungen (Control unit adaption) ->F3
Programmieren (Update) von Steuergeraten (Control module programming) ->F3
Steuergerat programmieren (Auswahl) (Program control unit (Selection)) ->F3
Now we have 2 options to flash the ZGW/CGW with, choose the correct one
Don’t panic ! if you choose the wrong file , it terminates process and you can do it over again
Confirm Flash pop-up with Ja (Yes)
After that it says : “Das Steuergerate wurde erfolgreich programmiert”
->”OK” it ask for a reset -> JA (Yes) ->
ECU Reset (FN_ECU_Reset) ->F3 again ->F3
Now you Complete full History wipe
Enable Comand DVD/TV in Motion (W211 W219) and OTHERS
USE THIS TIP WITH CARE AND COMMON SENSE !!! AND OBEY LOCAL LAWS.
In obd2tool.com Vediamo Developer mode :
Audio, Video, Navigation und Telematik ->F3
a screen might pop up with all kind of settings, ignore and press F2
New screen with ESD warning ->F3 COMAND /AUDIO -AUDIO 50 oder COMAND ->F3
Entwicklungsdaten ->F3
Steuergerate-Anpassungen ->F3 Steuergerate-Anpassungen (Variantencoderierung) ->F3
HU Parameter ->F3 scroll down to line: Driving speed is more than 0 kph and
Driving speed is more than 10 kph and BOTH enable them and ->F3 to confirm coding
Now you be able to watch DVD/TV when car is in motion
Uprate the speed limited in a gasoline (ME-series controller) engine control unit
Log on to DAS, connect to the car, select:
Control Units -> Drive -> ME-SFI 28 -> Development Data.
Then select the Control Unit Adaptations -> Explizite Kodierung
This option works quite the same in Diesel engine models, however i found it more difficult to use (quite frequently modules are replying with an error message to the attempt of recoding). I was able to successfully remove the speed limiter on a CDI2 series module from the W210 model and some others as well.
Addrear airbags to the AB control module
Control Units -> Body -> Airbag (AB) -> Development Data -> Control Module Adaptations -> Variant Coding -> Fahrzeugausstatung Kodieren
(the last menu entry can be slightly d ifferent in various module variants)
Select the drop-down list in the field Airbag Hinten Rechts and Airbag Hinten Links – set to YES. Back up to the main Airbag menu, reset the fault codes, cycle ignition, reset fault codes again and cycle the ignition for 2nd time (this step is very important).
Addfog lamps to function as a cornering aid
Select Body, then Driver Side SAM -> Development Data -> Control Unit Adaptations -> Variant Coding -> Abbiegelicht set to ON (“ja”).
Then go to the Passenger SAM (if present, for example in 211/219 model series) and similarly, perform the same coding in the second SAM unit. I have found that quite often cars manufactured prior to year 2003 have the relevant cornering lights option available in the left sam, however right sam is missing it. Not a big problem since these are readily and cheaply available from the second-hand market.
For all the onboard systems to recognize the new function you will also need to recode the CGW or EZS and mark the appropriate factory option in the adaptations.
Hidden error codes
For W211/W219/W230 series with SBC system, go to the Chassis-> Sensotronic Brake Control (SBC) then enter Development Data then call up Fault Codes. Most likely, a car that has been driven for some time will have a code “Event: ABS Bremsung” stored. This Fault/Event is not normally shown in the general menu of DAS – it is being filtered. It actually
does not represent an actual error, just a specific condition (hard braking with ABS activation). You will find many modules that actually filter out some more or less useful fault codes.
This menu is also very useful when evaluating vague fault codes (ie: “Hydraulics fault” in the general version in the developer menu can be drilled down to something more meaningful like “rear left release valve stuck in closed state” – this will come in German though).
Adapting the SRS control unit to a new car (different configuration, different VIN).
First of all erase all present error codes in the unit if possible. If there are current faults the airbag module might not get properly reinitialized.
Then proceed to the menu control unit adaptations -> special functions -> Control Unit is released.
From this point do not turn the ignition off or reset the control module. Proceed to the menu option “initial startup” where the current configuration will be reinitialized and new VIN can be written to the control unit.
Please pay attention to the specified configuration (ie. Does the car have rear side airbags?) otherwise you will end up with a controller that does not recognize airbags installed in the vehicle.
After completing the initial startup, reset the control module (cycle ignition) and erase all fault codes resulting from the startup process.
Extend SBC life
UNDER NO CIRCUMSTANCES USE THIS PROCEDURE MORE THAN ONCE ON ANY CAR AS TRUE SERVICE LIFE OF SBC UNIT IS AROUND 160-180% OF WHAT MB SET THE UNIT AT
Make sure engine is running !!!
In Mercedes Vediamo Developer mode from obd2tool.com you need to go to Entwickelingsdaten – > ansteueringen -> Gesamstliste aller Ansteuerungen
to see how many times brake has been pressed there is a line that says: Bremsenzahler (DJ_GetBrLive)
then 1 line down there you see Bremsenzahler aktualisieren und Lebensdauerzahler F neu berechenen -> click it !
Parameter uINBR = 0
then click F3
1 line down Bremsenzahler auf beliebigen Wert setzen (DJ_SetNBr) -> click it
Parameter uINBR = 0
then click F3
then scroll down untill you see the line’s :
Lebensdauerzahler F neu berechenen (DJ_CalcLiveTime)
Parameter uINBR = 0
then click F3
Lebensdauerzahler F neu berechenen und schreiben (DJ_BuildAndWriteF)
Parameter uINBR = 0
then click F3
Log out of SBC !!
log out of verhicle !!
let engine run at least 10 minutes or drive at least 10 minutes
If no coils are damaged , SBC fault code is not AKTUEL no more
Desactivate seat children and ocuppancy seat in mercedes ml270 cdi
MUST READ !!
Warning !! Warning !!
After completing this procedure
NEVER use a child seat in this seat again
Warning !! Warning !!
EXTREME CAUTION TO BE USED WITH THIS METHOD
In obd2tool.com Mercedes Vediamo Developer mode , you have to Disable AKZE in passenger seat.
When you disable this feature, passenger airbag in Dashboard, will work ALLWAYS when crash signal come’s from the front of the car , even if no passenger is sitting in this chair . So in an accident from the front, you allways have to buy a new Dashboard + dash airbag as well
Important !!
After you disabled AKZE in SRS unit ,you will notice you can’t erase the fault , or another fault came back (fault coding).
To complete procedure , you have to unplug the Yellow AKZE connector under passenger seat, so SRS can’t measure anything connected on this input port.
Now you can erase Fault codes in SRS , and your SRS light in Instrumentcluster will go off
MUST READ !!
Warning !! Warning !!
After completing this procedure
NEVER use a child seat in this seat again
Warning !! Warning !!
Activate this secret function as litres, datum, bigger pictures/symbols of some check controls on all models
like W211

 
AGAIN! DISCLAIMER: The author takes no responsibility for any damage caused by use of the Developer Kit of DAS. This option is a very powerful tool but must be used responsibly and with extreme caution. If in doubt, please do not blindly try the menu options – several of them will cause EEPROM or FLASH memory damage, requiring the module to be disassembled and reprogrammed using external tools – this is a troublesome and risky operation. Unintentional actuation of components may cause mechanical failures or even risk of fire – please remember, that in obd2tool.com Mercedes Vediamo Developer Mode DAS will do exactly what you command, all safety checks and interlocks are bypassed!

How to change speed limit with pld files?

Q1:

Question about payload files:

I have pld files of my tractor (6330P) 11 in total.

I see in bottom of each files info about my tractor (option, serial number etc)

Question: My goal is up the speed limit from 40km to 50 km. I think I have to change OPTION=3 to OPTION=5, but do I have to edit each 11 pld file? 

A1:

You were right about the speed limit:

you can change OPTION=3 to OPTION=4 or any other you need.

Speed_30kmh = 1;

Speed_35kmh = 2;

Speed_40kmh = 3;

Speed_50kmh = 4;

Speed_ECO = 5;

Speed_NoiseRed_OOS = 6;

For R models the line is different. ROADSPEEDLIMIT=3 change to ROADSPEEDLIMIT=5 or any other you need.

var RoadSpeedLimit_30 = “1”;

var RoadSpeedLimit_35 = “2”;

var RoadSpeedLimit_3840 = “3”;

var RoadSpeedLimit_40E = “4”;

var RoadSpeedLimit_50 = “5”;

var RoadSpeedLimit_50E = “6”;

var RoadSpeedLimit_55 = “7”;

var RoadSpeedLimit_60 = “8”;

var RoadSpeedLimit_60E = “9”;

After you change it, sometimes you still need to lift the speed manually through the display (depending on the tractor model)

You only need to reprogram transmission controller for that.

If you reprogrammed all of them, some settings might have went to default so you might get up to 5 fault codes that you need to configure with SA.

Q2:

Does it work with SA 4.2?

A2:

Service Advisor is just a tool to use pld. Pld editor works without SA.

Q3:

I have a question about trying to up the power of a 6330 to a 6430. If I compare the engine pld of both tractor they are identical (just the info in the bottom is different) So I don’t know how it could up the power if all the code is the same??

A3:

most pld files are made for various models, the info at the bottom determines which part of the pld file will be used for programming. For example:

PRODUCT_MODEL_NO=6115

PERFORMANCE_OPTION_PART_NO=R546973

FACTORY_OPTIONS=RE570443
