Can any rear sam module basically be reprogrammed for my vehicle, or does it have the be the exact model 0025459701? I have a couple that are identical but different part numbers. I've tried to search sorry if this has been covered.

to do the coding correctly----you need the same part number----remember want you see on the outside does not represent the microprocessors inside.

I swapped a c230 front sam into a c32 and everything seemed to work. I dont know if that helps but...

Thank you. Hate to hear that as most of units local are a different part number

most W203 can be swap I did C32, C240 & C230 to My C320 but the best thing to do is get it out of a car that has the most installed Options..

I swapped my rear SAM on my s203 C180TK -05 (2035453101), to one from a w203 -03 220CDI (2095450701), and it works perfectly. An other guy over here swapped his w203 C200 -01 to one from a w203 -07 220CDI. Only issue he got was the fuel gauge not working. That one needed re-programming (have no idea why, as fuel gauge should be present on all w203...).

It seems like you can use one from any w203, but I'm unsure wether the donor needs to have same or more equipment than the pasient. I would guess that they don't build separate ones for the different equipment levels, but that it's rather the programming that are done differently. But better safe than sorry. Look for one that has the same or more equipment if possible.

07 is a face lifted model they changed the pump/filter/sender design.
