    Default Weird noise from turbo

    Just had car serviced and new EGR fitted, car drives so much better now but under medium-hard acceleration the turbo sounds like its switching on and off instead of making a continuous whooshing noise Acceleration doesn't seem jerky but don't know whether to take it in to garage again?

    It seems to start at 2k revs, so am assuming the EGR is working since it was replaced cos its driving much better than before
