Just got my car back yesterday after being approved for 2 new turbos! My dealer was great through the whole process even though it took roughly 2 weeks from start to finish. In case anyone is wondering or worrying about mods effecting the warranty, I have an injen intake, turner motorsport vent boost gauge and Cobb. Before I brought it in I put the stock intake back on and returned the ECU to stock. They didn't even give me a hard time about the vac line and ended up replacing it!
Car runs and sounds the best it has in a long time. Way to go BMW!
