I'm contemplating getting a Ghost installed. I contacted Autowatch head office and they arranged for their nearest approved installer to me to get in contact. They rang me yesterday, and were very informative and confidence-inspiring (it helps they're a firm I've done business with before, albeit about fifteen years ago). But one thing he did say, which I hadn't picked up in any of my research to date, is that some Audi models might need an additional analogue engine cut-out, and they won't know until they inspect the car at the time of installation. Has anyone here heard of that before?
