CAS4 failed after update. - Archimedz - 21-05-2026
Hi, CAS4, after update fail (ё5у5), founded CAN filter inside. After filter removed, update done with ё5у5, no any errors, all modules green in i5тд, remote and CA works, but can switch on ignition, only with key near steering column.
And biggest problem, starter cranking, but engine doesn't start.
SOLVED!! CAS4 failed after update. - Archimedz - 26-05-2026
A solution has been found. The keys have been renewed and re-added.
