I’ve bought a new/second hand ABS pump/module and the garage have tested it and it works however they have told me that it needs to be programmed because if they fit it, the EPB will seize on until it’s programmed.

Would I need to go to Fiat to have them fit and programme it or is it something that MultiECUScan can do?

Can’t find anything in MES. Apparently it’s to do with the serial number as the system knows it’s not the original one even though it’s identical.
