2 new turbos, new vac lines.
They have a procedure to measure tolerances that require them to make adjustments rather than replace turbos. Rattle does not always = new turbo and it does not mean they will always replace both.
They also have some guidelines on what is "normal" rattle. This is a mechanical device it does make some noise.
Only reason I got both turbos is because my car ended up with a new model turbo and an old model turbo installed at the factory. When the tech tried to work on them they were different and BMWNA told him to replace both.
