Strange Noise! Am i going mad?!

Hi all,

You will have to bare with me on this one.....

Recently I have been hearing a strange noise whilst driving.

Just a quick example: Came out from Blue water (Shopping centre) last night. Started the car fine. Put the de mister button on. Waited for the screens to clear and per normal fighting with the gearbox to engage any gear for a few mins.

Driving on the motor way fine..(De mister was off - heating set to normal half a fan 17Deg) Then when driving around residential streets I could hear what only could be described as water moving about or flowing around. I was driving at 20mph / 25mph so my passenger could try and locate the sound. I could not pin point where it was coming from and it seemed to stop after about Min of parking up.

Would this be something to-do with the heating system or?

Sorry for the long winded explanation!

Matt
