Modus Generator Fault

My 2004 Renault Modus (diesel) has reduced engine power, a warning light, difficulty starting, and weak lights. There's also a stored error. I suspect the generator. Could that be it, or are there other causes?

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.

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€.
