I know this has been talked about several times, but I just want to make sure I'm OK. I was looking at this thread already:
Should I be able to hear the turbo spooling?
Just recently I've started to hear my turbo spool up when I get to around 3k rpms. It's really noticable, not something I could have missed before. Nothing has really changed with the engine, except I installed a new air filter about a month ago. I only started noticing the turbo noise about a week ago though.
I was reading in that other thread that maybe a rubber grommet between the airbox and the air snorkel could have came loose, is that a possible scenario?
There is no noticable loss in engine power, nor does it feel like anything is really wrong, but still, as much as I like hearing the turbo (loved my TDI's whistle), it's not normal and makes me scared.
