Non-encrypted label files for MK25E1 ABS module?

[PetrolDave]

I am replacing my rear differential with no diff-lock for a unit with differential lock.

Your car WV2ZZZ7HZ8H133087 from factory has diff.lock, PR-code 1Y4

OP are you sure your rear diff is a no diff lock version, the PR code for your car suggests otherwise...

No that is not correct. See post #6

MK25E coding is not the same as yours MK25E1.
[22] coding 0000002 is with diff.lock, 0000001 is without.
Your car WV2ZZZ7HZ8H133087 from factory has diff.lock, PR-code 1Y4
Your [03] coding 0000607 is with diff.lock, like other Transporter with same equipment as yours is coded 0000607.

Again, is there a problem ?

Oh, thanks NETech, this is really helpful.

It seems that I do not have to change any coding then.

Up to now, there is no problem because I have not swapped differentials yet. I just wanted to make sense of everything before starting so that I do not do anything wrong. And after testing all the pieces the only thing that remained was determining whether my 03ABS needed recoding or not.

So thanks a lot.

PetrolDave, Indeed, it's a PR1Y4 . The thing is, the previous owner replaced the lockable diff by a non-lockable one. It seems though as when doing so he never recoded the ABS module to indicate that there was no longer a diff-lock.

Now I am just refitting a lockable diff on it to bring it back to factory specs.

I already plugged the lockable unit to the VCDS (just put it under the van and connect it) so that I could read the 00002 coding of the unit I want to install. Everything is fine:

Existing differential without diff-lock

Address 22: AWD        Labels: None
   Part No: 7H0 907 554 F
   Component: HALDEX 4Motion      2110  
   Coding: 0000002

New differential with diff-lock

Address 22: AWD        Labels: None
   Part No: 7H0 907 554 F
   Component: HALDEX 4Motion      2110  
   Coding: 0000002
   Shop #: WSC 02756 790 00000
   VCID: 33331D04772445EF045-5160

The doubts were on the ABS module but now I think all is clear. This module is responsible for enabling the diff-lock to engage if certain conditions are met at the time of depressing the diff-lock button: max speed of 40kmh, and max difference of wheel speeds L-R of 7kmh. This is why the ABS module needs to know whether diff lock is available or not. The coding I have is as so:

Address 03: ABS Brakes        Labels: 7H0-907-37x-ESP.lbl
   Part No SW: 7H0 907 379 R    HW: 7H0 907 379 R
   Component: ESP MK25E1          0104  
   Revision: 00H31001    
   Coding: 0000607
   Shop #: WSC 02756 790 00000
   VCID: 44D14ED8228AF257ADF-5160

According to NETech this code 607 is normal for the MK25E1, that is it corresponds to units with diff-lock, so I will leave it as it is.

So it seems that all the coding is correct so I'll only have to carry out the mechanical work. The previous owner did not re-code the ABS module, so I should be fine if I just do not touch it.

Trying to embed photos now...

Here´s the non-lockable diff coming out...



And here the lockable diff coming in!!!



Thank you all guys!

I finally did not do any recoding at all. The diff lock works great!

SO WAS FOD!
