After ECU repair, the car goes into limp mode with persistent fault codes indicating short to ground, and neither the specialist workshop nor the SEAT service center can resolve the issue.

Existing diagnostics (ODIS, manual ECU repair) cannot pinpoint the root cause of short-to-ground faults causing limp mode; they only reactively reset or recode without solving the underlying wiring or component issue.
