Modus Generator Fault
Summary of the thread
The 2004 Renault Modus is experiencing reduced engine power, a warning light, difficulty starting, and weak lights, leading to suspicion of a generator fault. The symptoms align with a failing generator, which is central to the car's electrical system. While other issues could mimic these symptoms, the stored error code and multiple signs suggest the generator is the likely cause. Consulting a professional is recommended for accurate diagnosis and repair.

The serpentine belt looks fine. If it is the generator, are there diagnostic steps I can take before going to a professional? Could other things mimic a faulty generator?

A failing generator can mimic other electrical issues. Trying to self-diagnose further can be frustrating and potentially damage other components. Given the stored error code and the multiple symptoms, the generator is likely the source. I'd advise consulting with a qualified workshop.

I took the car to a mechanic, and they confirmed the generator was defective. The total repair cost was 960€.

Sounds like a generator problem, especially with the weak lights and starting issues. It's like the heart of the car's electrical system, and yours is struggling. Is the serpentine belt okay? An alternator issue could also be the cause.
