Just came home from the dealership...
I wanted them to check out a loud whistling sound coming from the engine bay. I was adamant about wanting to drive the tech around but all of them were at lunch. I trust my SA so I leave to eat lunch and come back to wait in th waiting area.
They didnt realize I was there and I over heard the conversation the tech had with the SA. Apparently he raced my car with another to see if anything was wrong with it. They said the sound is normal and that my car was "snappy". Faster than the other car. He asked me if I had software on there right now. I was like "Nope", took my car and left. I'm thinking of going to another dealership and getting a 2nd opinion. If my car doesnt have a decrease in performance should I worry about the loud whistle?

So their diagnosis process was racing your car against another car? and you were ok with their results??
Edit* The other car they raced probably wasn't even warmed up yet.. hence your car feeling "more snappy" |

If the noise is an indicator of a developing turbo problem that will degrade with time, then there is a possibility that the turbos will let go and cause consequential damage to other engine parts like catalytics or engine internals. However, I think that complete turbo failure is not all that common, and most of them just die slowly and start to degrade performance. Seems that more and more N54 owners are starting to report this whistling sound, but I have a hard time accepting the dealer calling it "normal" when brand new cars on the dealers lot are not making this sound. |
