When i turn the car off, there's a 'humming' type of noise which stays on for about a minute or two - is this normal?
Just driven 18 miles, with aircon OFF, and the humming persists (I though it was the aircon system maybe?)
Is this normal?
What is it?!?!
Many thanks

It's normal. We think it's the vacuum dissipating, but they all seem to do it.
