My Superb makes a hissing sound for a few seconds when it is turned off, comes from the drivers side near the firewall in the engine bay. I'm not overly worried as I assume its something to do with the aircon and it doesn't get used much. Just wondering if anyone else had/has a similar problem.

Thanks

Your quite right this is to do with the Air Con and it's just the system 'shutting down' nothing to worry about it's quite normal.

I get the sound of the refridgerent continuing to pass through the system coming through the vents inside the car, as well as the external "hissing"sound too

One less thing to worry about so, thanks lads

Is it a gurgling noise, or more of a hissing?

If it's a hissing noise, does it go away if you depress the brake pedal? (Don't worry - I'm sure it's the aircon and nothing to worry about - just "belt & braces" check )

I get both!

If it's 'gurgling' then you might have problems ahead.....

Why mate?

Why mate?

Well......mine doesn't 'gurgle' so I assume it can't be normal....assuming you have the PD TDI engine?

No it just hisses, tried pressing brake pedal doesn't make a difference. Hopefully not a developing problem.

Nah mate it's definately the Air Con....nothing to worry about.

Thanks man, good to know.

Yup - PD140. It only lasts 5-10 seconds in any event, so if it gets worse, it'll be down to the dealer for a warranty check....

Yep, definately the AirCon, mine does that too.. also sometimes I can hear the Turbo deaccelerating too..
