2008 Mercedes C300 W204 ABS module replacement/ reprogramming

[lucas7117]

Situation: ABS/ESP had internal electrical problem. We replaced ABS/ESP unit (just the brain) with used one.
Same part numbers. Were able to do manual coding replacement of ABS/ESP N30 module with calibration of inlets/outlets/road test.
No more codes from ABS/ESP but the HOOD OPEN sign is always on. Replaced a connector. Same thing.
Have anyone had similar issue?
Using autel maxisys elite & matco maximus 2.0 (launch x431).
Any input will be helpful.

Seems like Rear SAM had to be updated and adapted to New(used) ABS module..
Live and learn..

Cool, did it HAVE to go to dealer online coding?
if so what did they sting?

I believe the autel can do these.

No, I had to bring to another electrician with better equipment than mine

Autel was able to do online coding but only for Virgin ABS module. Because I got used one I had to do manual coding
and then rear SAM didn't matched some values and needed to be adapted.

I believe the autel can do these.
