Hi,
I just notice, that when starting, illumination lights behind the clock flickers.
Is this normal feature for the Punto, or is there bad earth connection?
Everything else works fine.
You mean they flicker while the engine is trying to start? If that's the case then you need a new car, lol jk. It's fine, it's just the voltage drop as your starter motor is drawing heavily causing your lights to dim / flicker
