Mercedes offline programming/coding recommendations and guides:
Offline coding:
SCN or CVN coding was added to the automobiles back in 2003 if not earlier . The idea of OFFLINE coding was to become capable to create SCN codings whenever you don’t have an world-wide-web connection at your workshop to be capable to execute this on-line. In both situations an SCN or CVN coding was necessary.
Let’s not confuse OFFLINE coding with basic CODINGS !
Codings could be completed with standard DAS or Developer DAS extra deeply. Coding doesn’t imply that you just need to replace your unit application totally. When you have to produce an Offline coding this implies to flash your unit with an updated application version or a minimum of exactly the same version which you have got currently (not sure in the event you will likely be capable to downgrade your software) and after that SCN code that a single to be activated within your auto. I’m not conscious of any car or truck which is usually OFFLINE coded without having the request for an SCN code.
The only good point right here will be the time required to perform this. Yes , you can make OFFLINE coding together with your technique then go back for the dealer and ask them to produce an SCN coding for you…however are u sure they’ll not charge you the same amount as if it was done in their workshops ?
The internal VIN of this auto (e.g.w211): is WDB2110261AXXXXXX
The first letter of the external VIN after “WDB” gives the physique style, like
– U for MB implies 211
– F signifies Sedan
– next two digits will be the model inside the body form, appears to be a direct copy in the internal VIN
– subsequent digit is in regards to the SRS system, I’ve found explanations as much as the letter F, so this auto should have additional SRS equipment than known when my reference was drafted
– position 9 is actually a verify digit and the tenth digit comes from the model year.
It is considerably a lot easier to seek out this if you enter the external VIN to EPC and let it decode the internal VIN for you personally. Then choose up digits 4-9.
Ps. 17-digit code & 6 digits of numbers
Office programming:
For those who want to program ecu ‘offline’, there are several options:
1. In DAS, you are able to program ecu’s offline. (In xentry, you have to buy xentry calculator.)
2. Vediamo may be the way to go to program ecu offline and is used by daimler factory
3. Should you want only for 204.041 as above, you are able to try to use 204 in DAS. and there is free offline programming
between those three options, vediamo could be the best and could be used for 99% vehicle’s model
Noe that: For those with Star diagnosis for 100usd around. DAS is your way to go.
DAS (older models before 2011, but still most cars communicate through this program)
Xentry (new model automobiles 2011-2016)
Should you set it up correctly, it is possible to program offline in DAS only. Then if we need to go online with DAS we switch the modified flash folder to the original.
Xentry there is no offline programming, only on the internet. Obviously, you need to have login and pass to go on line.
Btw, offline programing is an ancient way from the service,..nowadays its better to use on-line services,…its safety,..and quickly
The last, how to enable DAS for offline programming:
Option 1: (try on your own risk)
It’s very very simple to enable “Offline” programming in newest DAS version
copy this file to
F:\Programme\DAS\trees\pkw\flashen\ini
(click yes, to replace existing).
And Be Happy !!!
in case you not have this function for any concrete automobile – verify initially six VIN digits for this automobile, and add to this file in model section.
for sample – to enable option for WDD221054 – add text string to file :
221.054=YES
Option 2: (try on your own risk)
Open F:\Programme\DAS\trees\pkw\flashen\ini on the notepad and add ->
1st of all
—-A451—-
451.331=YES
451.332=YES
etc
etc
etc
IMPORTANT!!!!!!!
The options above are diy solutions from DAS users.
TRY ON YOUR OWN RISK.
NO A single HOLDS RESPONSIBILITIES For you.
If solutions above remain useless or you want a solution WITH SECURITY, please try option 3, the idiot solution.
Option 3: (use with relief and security)
Spend a little bit money on an enabled DAS for offline programming.
Though the DAS 2012.11 version is kind of old, this is definitely the one we highly recommend. It has been tested for thousands of times on vehicles, verified to work definitely.
And it also could be come with the full package V2012.11 MB SD Connect C4 with DELL D630 laptop, very convenient for customer who do not have DELL D630 laptop or do not know how to install software correctly.
This will save a lot of time for urgent needs. That is, users can directly use this set for offline programming when they receive the package (including setup offline mode in old DAS software program) and open the function. But they need set up WIFI and Lan cable connection by themselves if wanna do on-line programming.
In short,
For offline programming,
DAS 2012.11 is definitely the best solution for old automobiles before 2010.
For on the web programming,
You can use the latest version 07.2018 or 09.2018 Xentry program for the old and new cars.
