Afternoon all not posted for a while due to work commitments just need some help please.Recently took my car for a M.O.T passed with flying colours next day later fancied a spirited sunday drive so turned boost up and off I went, when stopped at lights noticed smoke coming from engine bay popped bonnet and smoke was indeed coming from the engine bay with (burning or melting smell from infront of turbo somewhere) but not blue smoke clear if that makes sense, so turned boost down and limped home.When I arrived home no smoke and I have noticed this only happens when boost is turned up car still hits full boost and pulls as normal also no blue smoke on start up or at any other point just need advice on what could be wrong as funds are a bit tight until pay day PLEASE HELP me on what could be wrong.
