I have had my 2006 seat leon tdi for about 2 months now and it has been more times in the garage than I have actually driven it. Got it back about 2 weeks ago and thinking everything was going great now the same problem. I would be travelling along at 70/80 and then all of a sudden the car would start to loose power and at lower speeds there is no pick up at all!! I was told that there is a dump behind the turbo which had got sooted up but this cant be the problem again, Any ideas??
