n54 Bird Chirp sound (New Turbos)

Hey guys
I have a 135i Full bolt ons and I recently got my turbos changed under warranty
for blown turbo seals on Dec 15th 2012. About 2 weeks ago I started to hear this weird annoying bird chirp rattling sound. The car is at te dealer now
The tech lubed up and adjusted the wastegates but they are still making that noise . It makes the noise when I first start it up and I rev it a little and let the peddle go and lasts about a minute, after that you can't hear the noise anymore and the turbos boost and hold boost perfect .This is really annoying lol

Please post any comments or suggestions.

Thanks

I would say its the wastegate position when cold or initial start

I had something similar and adjusted this with my procede software and a laptop

FBO and they warrantied your turbos? Did you take off the DPs prior?

I had this same issue only when it was really hot out last summer. We had temps around 100 and it would happen at 4k only. When the temps dropped it went away, but it seems that it could be with an issue related to where the downpipes bolt up to the mid pipes. Downpipe flanges being off. BuraQ had this issue as did one other member (besides me).

I have a friend at the dealer so he took care of me
I almost 100% it has to do with the wastegate
I'm picking up the car today since they can't find what's causing it
