UCDS Forum

I upgrade the IPC, BCM and PSCM using Upgrade Wizard, which completed successfuly. BUT Power steering would not work and had "Power steering malfunction" on dash. I managed to downgrade power steering module to original version and it started working again. However, original versions of software for BCM and IPC are not available.

BCM - the upgrade resulted in a corrupt EEPROM message and i could not write config to BCM at all; but vehicle still worked using IPC config. Is there any way to recover the faulty EEPROM issue?

IPC - I now have an error U2101 "Initial Configuration not completed" "Adaptation Limit Not Reached". I have rolled back to the earliest version availablle in UCDS (about 5 revisions newer than what was on there), but the error still exists. Is there any way to fix this problem?

Tried to reset modules?

Yes tried a Reset on modules multiple times, even disconnected battery for 24 hours but still the same.

Have replaced the bcm which cured that but still the same problem with ipc.
