Well after all my complaining about that other irretating noice, Iv got another one a really scarey clunking noice. It sounds like its coming from the engine bay and I can hear it when I take my foot off the accelerator, sounds almost like a flat tyre or bad road surface. Its very worrying, Im thinking the following heatsheild or intercooler rattle? But Im not the most technical person so anyone else got any ideas?
