Hi all,

After driving the car with aircon ON for a reasonable distance (say > 20 Km) and then park into the garage and shutdown engine. I came out of the car and notice a gaseous sound emanating from the bottom of the engine bay. It happens every time.

I think I have this since day one and I don't remember hearing this if I drive with the aircon off. The sound goes off after 5 - 10 minutes.

Just want to check if any of your Euros is exhibiting it? What is the cause and is it normal?

Thanks.
