Insignia Overheating Bypass Valve Error

Error codes and overheating are never good. Any engine stalling or rough idling? Have you checked the vacuum lines for cracks or leaks? Even a small leak can cause issues.

No stalling or rough idling, but the engine lacks pep. I haven't inspected all vacuum lines. Did your error specifically point to the bypass valve?

The error pointed to the bypass valve, but it was a faulty sensor causing the bypass valve to malfunction and overheat. I'd recommend a diagnostic check at a trusted workshop.

I'll schedule a diagnostic check. The error was a stored error that wasn't cleared after the original repair. The repair cost came to 0€ since it was not a new error. Thanks!
