Hello everyone, drive a Fiat Punto 176, built in 1996, 55hp. The car has now run exactly 58000km and it was already a lot defective or worn out. 3x ignition coil, 2x spark plugs, electronic problems, brake discs, brake pads and then last month the clutch. The following problems I have now since the latest… In standing and driving (there is gas) it rattles very under the car. I guess it’s the catalyst. The sound gets worse every few hundred kilometers. It was easy and rare to hear. Now it is always when driving. Can it possibly be that the catalyst is defective? I would never have heard of this before. The catalyst does not actually break…. :/ MfG Skaarj85
