Thinking of replacing your ABR/ESP module? Here's my story.



300408;0160;FV;L;2214421153;ESP;M005;050;20060331-20070317;2219029602;2219029602_001.CFF;1;
M005 is for 4Matic.
221.etns (etne, etnh, etnt, etny, etnz) are located at \Program Files (x86)\Mercedes-Benz\SDFlash\Release\PKW
For the 2214420653 there are 6 entries, none with M005 as above, for different dates of manufacture and engines like the M275, M156 and the latest update for that software is 2219029502 for the rear wheel drive cars. To see if I could trick DAS into flashing my control unit with 2219029602, I copied the above entry but changed 2214421153 to 2214420063 and placed it at the end of the software list for 2214420653. When I tried the offline update I got a prompt of new software available for my control module and was able to use DAS to flash 2219029602. All of the ESP errors went away and things are now back to normal. For those that don't tinker i.e. don't have Xentry/Vediamo and are contemplating replacing their ESP module with a used or reman unit, you must know what car the unit came from and/or make sure it has the same features your car has or you will have problems. For the tinkerers, this piece of information hopefully can be useful.

certain modules will update simply off line with old kit and software contained within pre 2012 tools
others fight even with latest fully paid up dealer tools online and software pulled of the Merc local encrypted NAS drive
others refuse to install via vediamo even with experts at the helm with unworkaroundable security limitations
with something that has its toes in to so many systems and safety related not surprised they fight....
my 2 wheel drive 2006 V8
ABR HW 221545 5232 - SW was 221442 0653 of week 29 of 2005, mine is updated to SW 221902 9502 week 17 of 2011 - suspect its steer assist update - not that its enabled - never tried - only thought why they issued after recent post and read its steer by brake)
not seeing that part used on any 4x4

had lots of trouble flashing SGR radars took 5 attempts online before Merc manged to flash it - oddly the progress bar seemed to get a little further before crashing each time



As for the 221.etns...
Your Xentry/DAS configuration is missing files which may be in an archive as part of the installation located at \Program Files (x86)\Mercedes-Benz\SDFlash\Release\PKW named #CFF?.zip, where ? is 1,2,3,4,5,etc. Those are all of the CFF files. I don't remember if the etn? files are contained in these archives. I you send me a private message I can provide you with the ones you need for the 221.

On a separate note...do we know specifically why these fail?
merecdes had then soldered so the link wires would just fall off from vibration - see also Turbo VGT actuators (re-solder)
after those bits of fun became common knowledge they invented a more "random" method of failure - particularly welcomed by BMW who seem to have a race going on with VW over who can produce the biggest numbers of ABS failures.. here they get their units specified with the brush Guides on the ESP pump pressure motor set deliberately tighter than Ford (and I guess Merc do) as its rare on both
Looks like I might have the same problem I just wonder if you had any fault codes besides esp light on the dash?
My car has esp light on the dash and is throwing this code.
This fault code was not on before ESP module replacement.
My ESP module broke down, I replaced for a brand new genuine unit, however I was not able to do programming/coding stage on my xentry, so I did all that in my friend mechanic's autel. All codes related to ESP module were gone, no more stiff power steering above 20mph, so let's say we did some progress. Now I have this code and esp light on the dash. I did replaced that sensor that is related to this fault code, nothing change. In Xentry it says it might be a bad connector, I ordered a new one that is coming this week, but honestly I don't think it will fix the issue.
I tried to go in Vediamo and look for the files you mentioned, but I think I have some cheap Chinese version and can't do anything in my Vediamo. Now I'm waiting for BenzNinja software, hopefully I'll be able to do things like that in their software.



My software number is 2219021703
How to determine if that software if appropriate for my car? Do I need to install old esp module and read the numbers? If I install old module, do I need to program it again to read the numbers?
I dig again into this fault code after I read the numbers and it looks like BAS travel differential sensor doesn't have connection with ESP module. Does inappropriate software might causing this lost connection? I already replace that sensor for a brand new genuine part, checked the wires, everything looks good.

from the video in post #14
Iff SW programing set to Auto, system is not able to find the new SW or the right and lastest SW compatible for your vehicle, tool just simple flash the existing SW of the ESP
If you select SW programming manual then you able to enter the SW version you wqnt apply to your ESP
The ESP from W221 diesel donnor then therefore Cruise Control does not work when it installed in my car. I hope 2219029502 is the right SW for my W221 RWD equipped with M273 engine + Distronic Plus. New SW flashing is successfully completed and ai have no time to test cruise control yet but I think it should works.
