    Weird noise under boost..turbo dying?

    Got a weird one. So I've noticed within the past few weeks my car makes this really weird high pitched clicking noise under boost on cold starts, sounds normal right? Just cold oil take it easy etc. However, it seems quite unreasonably loud just for cold oil and lasts for 5min of driving. What made me post this thread though is that it's doing it on hot starts now

    Here are some clips, hopefully they are good enough to pick it up.

    1:11 and 1:50

    Inside the cabin, it's harder to hear on camera but its very noticeable driving.


    Thoughts? Run it till the turbo dies? 99 AEB 139k, APR chipped since 127k btw, thanks for all the help.
