So i got water in my sam module...Change the SAM after i got christmas lights in my dashboard and everything is working again. BUT the HOLD function dont work it says "mercedes hold function not working check user manual(but in swedish)"

When i check in Xentry i get two codes.
47D8 And 5490.

Can anyone help since im stuck with the hold function not working.
if you know how to deactivate or fix it PLEASE i need your help.

 

Was the replacement SAM used or new? A used SAM will function but will do so based on the configuration of the donor car. The coding from the old unit SAM needs to be uploaded to the replacement SAM.
