Hello together, I would need help here from the Fiat specialists. Fiat 500 1.2 69ps 2008 build year Although I bought a Fiat 500 at which I noticed on the home drive that car exactly at 3500 turns is getting loud it sounds like from the gearbox and writes and hums very loud as soon as I go up to 3600-3900 turns it’s gone it’s in 4 and 5 strokes worst with the other courses it’s not so noticeable. All walks go in perfectly and out no one lei problems, add that car vibrates from 145kmh. I really have no idea what it can be very grateful about any advice.
