Yeah the whole trade in talk to bumper got my alarm bells ringing. He pretty much told me to offload and start again. That I'd got it cheap (1500 from oscar) and that I'd been taught a harsh lesson. He never suggested maybe a loose wire and I emailed him the video too. I was polite and in desperate need of help. Real worry. I'm a first time buyer and know techs are in high demand but this experience has left me in real fear of future problems...

The real fun is learning how to fix them yourself with the help from the great members on this site
