Hissing noise from rear?

[robsco]

Took Miss Robsco out for tea tonight, and thought we'd take the Alfa. When we pulled up in the car park, I turned the engine off and heard a hissing noise coming from the near side rear. Swore a few times thinking there was a nail through the tyre, but I checked it thoroughly and there was no problem. After about 2 minutes, the hissing went quiet and then stopped.

Its the first time I've heard the noise, and it never made a murmur when we got home. I'm utterly confused; does anyone have any idea whether its something I should worry about?

Happy new year to all.

Maybe the fuel tank not venting properly?

Or the snake on the badge has come to life!

Cheers Sunbeam. Would that be something to be concerned about?
