What's that noise?
A handfull of times now I have heard "something" behind me in the engine bay spool up and run for a while and then shut off when I kill the engine. It's definately an electric noise. It almost sounds like a fan or something. What is it that's back there that would be making that sound? It's a MY2003 Boxster.

:dance: I have heard it as well, I would be curious also.

Well at least now I know that I'm not crazy. :-P

If you hear it when you first start it up, then it automatically shuts down after a couple of minutes, it's probably the secondary air pump. Mine is pretty loud because a bearing in it is starting to go. It's a high-pitched whine.

old thread, I know.. but suffering the same noise lately...
i'm aware of the air pump that comes on during cold starts and that is working fine, but now im hearing a "whining" sound which sounds like a belt grinding into something.. (all my belts are fine and intact though) i think i've seen that this air pump is no cheap fix... is it possible it's the exhaust electrical fan? any way to test it without having to wait for engine to heat up to temp? |
Air pump 'whine' noise?
Searching tonight...For the first time I am hearing my air pump whine on a cold start up. Does that mean it is going bad, or is it normal? :confused:

Thanks Jager
