HW and SW part number/versions
hello all
im sorry if its too many question
i get many cars where customers needs update or dpf back on and egr on, if i update ecu with same SW number but different version, would that brick the ecu?
if i update ecu with same SW number and same version would that back dpf on and egr on ?
and lets say i have two ecu's, donor and original, both have same HW number but Different SW numbers can i reflash / update / write virtual to the donor ecu the same SW and Version of the original ecu ?

RE: HW and SW part number/versions
Really easy and safe to find out
Make full backup on bench,

Do what you gotta do - try to downgrade/upgrade sw trough OBD,
If that works - job is done, i it bricks, - write backup in bench!

Case closed
