Renault Wind Bypass Valve Error

I had a similar issue with my Wind. A bypass valve is part of the exhaust system, controlling the flow of exhaust gases. The error message is probably a consequential error, meaning that it's being triggered by something else going wrong. In my case, it was a vacuum leak. Did you check the hoses?

Vacuum leak, huh? Interesting. Where should I be looking specifically? Are there any common spots on the Wind where those hoses tend to crack or come loose? Also, what do you mean by 'consequential error'?

Yeah, vacuum leaks can be tricky. By consequential error, I mean the bypass valve error might not be the root cause, but rather a symptom of something else messing with the system. As for specific spots on the Wind, I can't really remember the details. If I were you, I would go to a workshop to get it checked by a professional.

Thanks for the advice! Turns out, you were right about it being a secondary issue. Took it to the workshop, and they found a coolant leak that was causing the bypass valve to throw an error. Fixed the leak, and the bypass valve error is gone now. The best thing is that the repair was covered by the warranty, so the repair cost was 0€!
