On the way to work this morning I put my foot down and when getting to around 3-4K revs the car stuttered, felt like the throttle being cut/traction control cutting in, but I didn't have the traction control on. It kept doing it until I heard a loud bang and after that from 2k revs onwards (turbo cut in), the turbo sounds loud and grindy when it cuts in. I didn't dare put my foot down after that! Any diagnosis guys? Clearly I'm taking it somewhere today to be checked out but I would appreciate everyone’s speculation Only had the thing 6 weeks, wounded
