My Punto 176 and his problems

Hello together, I couldn’t pull a more appropriate headline out of my brain than that, so please don’t stony me 😉 To the problems: 1. If I drive up or down a bit then the petrol needle sinks rapidly down and you might think that there is a leak somewhere. But if I come back to a straight level then the needle goes up again. (Of course it may be that it is just like that. But asking will not damage) q 2. My driver lock is in winter only Now I’ve already got enough WD40 powdered in, but nothing happens. You can see that you can lower the button a millimeter, but not more. But from the inside you can push normally. Does it hang on to the locking system or on the connection? Or does this also count to the age layer? 3. My main problem: When I turn on dipped light, only the parking light control lamp that had been there before only lights up. For a while, the dipped-beam control was Is that just the control bulb, or is there a mistake in the electrical system? 4. Something else to smile at: When I did clean up, I found a large iron tube under the cover of the loading floor. Does that serve to the stability of the trunk, or is that from the previous owner? What about: There is no bulging and it fits exactly in from the length up to 10cm. That’s how it should have been. That’s enough. nke already in advance. Greeting informed
