Hi. We recently bought a 2014 guiletta 1.4 petrol progression and we have noticed that it makes a strange noise when driving. It's difficult to describe the exact noise but it's a knocking/clunking/rattling noise that is coming from somewhere. It was more apparent today when accelerating hardish but driving at normal speed it was fine. Not sure if it is the exhaust or gear box or engine. Anyone had a similar experience or can give us any advice would be much appreciated. Thanks.
