Hey Scott I got a 07 Beamer 335xi and on cold starts you can hear the wastegates rattaling. Is this a sign that the wastegates on the turbos are about to go and I should worry about it now or do you think I should ride it out till I hear a rattling when the car is hot too. It cost a stupid ammount to fix the turbos and even if I DIY it is gonna cost probably 2 grand or so.

ride it till it acts up or until it makes horrid noises all the time the engine is running
