Yeah that's what I told the guy, I mean they are a vw repair centre so they should know what they are doing. I was told they would have no reason to touch it but still, it was working like a beaut before I left it in and now it's disappeared. I fail to see how you could manage to kick it, it's well tucked away. Yeah the polystyrene box is just Velcro tabbed on.
Thanks for your help, I just couldn't see what the purple lead connected too.
