Hi,
I do recall the noise also coming when letting go off the brake pedal. I'll do it again tomorrow and check if it also happens when moving the gear selector.
When you mention "footbrake", you are referring to the brake pedal right or the footbrake (parking brake)? Sorry was a little confused
Once I sat in the car I released the footbrake and didn't apply is again until the end when I was turning the car off.
