Not as easy as that , Bearheroes seems to know a lot about isn and syncing cas units ,its going to be a similar exercise to your ML problem, regards

Which DME is it?

Yeah, you will need another tool for none dealer procedures. BMW Explorer, or autohex can for sure do it.

Cas2 will never work with tricore ecu.

ok i will see if i can get them part numbers cause im not to familiar with cas2 or cas3 How about starting the thread with telling us what car you are working on, like YEAR / MODEL / ENGINE? Also, DME part number would be nice. You can do that or is it too hard for you?
