Symptoms suggest potential control module issues. I observed similar behavior in my previous Renault Megane, though the specific fault codes differed. Have you attempted accessing the error memory using a diagnostic scanner? Resetting the codes could offer temporary relief, but if the root cause persists, the error will reappear.

Yes, I have a scanner and I did reset the error codes. They reappeared after a few kilometers. Are you suggesting the issue is unlikely to be resolved without professional intervention?

Based on my experience, a recurring fault code, especially one impacting multiple systems, often points to deeper underlying problems such as corrupted software or a faulty control module necessitating professional attention with specialized diagnostic equipment. It is highly advisable to consult a qualified workshop for comprehensive diagnostics and potential reprogramming. Ignoring it may escalate into more serious problems impacting engine performance or safety systems, and could potentially cause consequential damages. This is an expense but might be worth it.

Thanks for the insights. Took it to a workshop, and you were right. Incorrect vehicle coding. Recoding the control module plus labour came out to 360€. Appreciate the guidance.
