As my driving is a bit less and is mostly out of city roads, couldn't hear this before(if at all it was there). Recently when I started to drive to office, while driving in the office basement (no external noise), when I was going over those small speed breakers, at crawling speed in 1st, when the front wheels would go over it I hear some "hiss" kind of noise (coming from front suspension - when they would compress while going over the bump). Noise is something like a quick release of some air. It comes only from front side only. Checked carefully while going over any speed breaker, this noise comes most of times. Anyone else has experienced it? Any suggestions? Car & Model: Punto 1.4 EPack, July 2009. Odo reading: 14,500km's Thanks.
