Hello. I have a 2007 audi a6 2.0tdi BRE engine. Car is like a living nightmare. First the oil pump failed, fixed that up. Then the turbo blowed. Changed that. And now after the new turbo instal its about 400-50km that i drive its coming a lot of blue smoke out of the exhaust. It was a strange noise like the turbo snaped metalic noise that hit the inside of an exhaust pipe. I thought it was the turbo again so yesterday i took off the turbo but it still looks like brand new so what else could be wrong? Could it be ccv valve? By the way ccv pipe that goes to the intake is oily so i believe the turbo looks wet of that. Then there was also a melted exhaust gas temperature sensor that i changed and after i changed the sensor the blue smoke appear so could it be something connected with that? Thanks.
