Installed a genuine S3 intercooler, finished just before it got dark. Took it for a spin round the block, as soon as I put my foot down I heard a massive pop/bang and woosh and then I stalled, restarted and managed to get home. A quick look in the dark with a torch the drivers side intercooler pipe has popped off on the stock metal coupling end!? Obviously didn't pay attention to the clip as i took it off..... hopefully will have it sorted tomorrow.
