Hi All, My MJD is producing a hissing noise when idling and I've noticed this noise from the day I bought the car ('09) . When I start the engine and idle I hear a sssssssss noise coming from the outside. (When i stand outside the car) There is no In cabin noise but yday my cousin was quick to catch this noise and found it a bit odd.( His linea does not make this noise) I wasn't worried till now because it was with me from day 1 so i presumed that this phenomena could be because of the turbo bleeding air. But now especially after I was pointed out that this noise could be because of an AC leak , I'm a bit worried. Does other punto owners also have this same issue?
