Beeping and Car Symbol on Dash Skoda Superb Mk1

Hi All,

Yesterday when driving a repeated beeping noise started and lasted for about 5 seconds then stopped.

At the same time the car symbol lighted up on the dash, as it does when a door is open, however it was the whole car.

This happened again today, but happened several, circa 5 times in quick succession, again, with the car symbol lighting up in full but with no message.

I have noticed this happened when the car blower was on, but not when I turned it off, so not sure if related to that?

Has anybody else experienced this and can advise on the cause?

Ben
