C30 Intermittent Starting Issue

Sounds familiar! I had a similar problem with my C30. Did you check your starter motor? When you turn the key, does the dashboard light up normally, or does it flicker like a faulty bulb?

The dashboard lights behave erratically when the engine won't start. Could that really be the starter motor? I thought that meant car electronics failure, not the starter motor.

That's exactly what happened to mine. The flickering lights were a symptom of a larger problem. I initially suspected a simple fix, but it turned out to be more complex. I'd advise taking it to a workshop for diagnosis. They'll be able to pinpoint the exact cause and provide an accurate solution.

Thanks for sharing your experience! It helped a lot. Following your advice, I had the car diagnosed. A defective fuse was indeed the culprit. Repair cost me 52€. Your analogy about the dashboard lights was surprisingly accurate!
