Hi

Recently bought an r50 Cooper lovely car with some gremlins.

Main one was abs trifecta with extras and speedo not working Also had seatbelt warning cruise control and dsc lit plus cluster displays “CoDE”

Background Info:
Recoded the abs unit to defaults using ncs expert this cleared some lights to standard trifecta (down to flat tyre, handbrake and abs)

Inspection of the can wiring at the abs unit identified a broken can high wire

soldered and heat shrunk cleared down all codes with ISTA+ green lights across the board and speedo now functioning, all warning lights went out.

However the kombi unit still says “CoDE”

Tried to factory code using NCS expert but keeps failing with ECU rejected

I’ve looked at the central coding details with INPA and all checks out I’ve run the diagnostics in ISTA+ and all seems fine ISTA+ reports no fault codes at all bar radio (after market fitted)

Main Issue:
I can read the module using ncs expert but not write to it

“CoDE” displays instead of mileage etc

Any ideas how to proceed or fix this?
