Megane Fault Code

Fault codes on modern cars can be tricky. Have you tried using an OBD-II scanner to pull the specific fault code? Knowing the exact code will help narrow down the possibilities.

I don't have a diagnostic scanner. Could incorrect coding be causing these errors? If so, how could I fix it without special equipment?

Incorrect coding can definitely cause those kinds of errors. Unfortunately, correcting the coding usually requires specialized equipment and software. It's probably best to take it to a workshop that has the Renault-specific diagnostic tools.

I had the vehicle examined by a technician. The coding was indeed incorrect. The repair cost 360€. Thanks for the help.
