Strange noise

[Chris B]

On our first weekend away in new SE, 4am listening to the birds waking up, we were using the lower bed with roof and upper bed raised, heard noise which sounded like the roof motor, lasted about 5 seconds. Definitely not down to us, anyone guess at why this happened?

Automatic tensioning . It was the motor, makes you jump always seem to be early morning.

Thanks, did wonder if it was something like that but didn't realise it was that clever!

It's a VW.
