One for the Experts!! - ESP and SBC version mismatch?

[Daxyz]

Hi all - here's one where I need some help/advice from the experts!

I've changed out my SBC unit for another that I refurbished (new accumulator and motor brushes) and after recommissioning with my recently acquired Xentry software the SBC system has passed all it's self checks and is now 'no fault found' - HOORAY!!

However - on the ESP module I now have the following error:

C1611 - Test CAN connection to A7/3n1 (SBC Control Unit)

with the possible cause and remedy of:

"The version of control module A7/3n1 (SBC control unit) does not match control module N47-5 (ESP, SPS[PML] and BAS control unit)."

Everything seems to be working and the possible cause looks reasonably self explanatory - question is.......what to do about it??

Refurbished SBC unit was from same year (2003) or at least the seller claimed it was.
I still have the original one and have refurbished the motor brushes on that one as well, so could put it back in with the new accumulator.
However I noticed that the brush cross section on my 'original' unit (approx 5x5mm) was noticeably smaller than on the 'new' one (approx 6/8mm) - so I'm keen to stick with it if possible.

Any help gratefully received.

I have been there. I even tried swapping in the matching bas control unit, but that didn’t work either. If I remember correctly the wiring loom is different too. I went back to the original unit which we had refurbished. Sorry can’t help you more than that.
