Default Auxilliary turbo coolant pump no longer working?

I just noticed last night and again this morning that the nice little gurgling/whirring noises that used to come from the passenger side of the engine compartment after shutdown aren't there anymore. What should I check to get them back?

Default Do you have the 225?

I'm not sure about a gurgling noise, but on the 225 the pump should run about 5-10 minutes after shut down. On mine it sounds like an electric motor running under the hoood.

I don't believe the 180's have them.

Default Yup, 225

And I know what is should sound like, it just doesn't anymore. And about a week after having my APR chip installed too! (I did hear it in the past week. It just stopped last night.)

Default I'm not sure what you guys are talking about but my turbo fan only comes on-->

if I don't give it a chance to spin down. The manual says 2 minutes before turning the car off. I get around that by coasting down the hill to my house or stopping to check the mail box with the motor running. We have one of those 'community' boxes. Sometimes the fan comes on when it is really hot in the summer.

Default Additional data

So I pull into my garage tonight (after a slow, precautionary cool-down cycle over the previous 2 miles), let things idle for the now obligatory 2 minutes, turn off the ignition, and I hear the fan (not the water pump) kick in for about 20 seconds on high (happens when the engine has been really active). I then pop the hood for additional cooling, and voila, I hear the familiar recirculating pump again. I'm thinking (wrongly) that despite what I've read and experienced, maybe it is temperature sensitive after all. But no, I check it again in 2 hours by just turning on the ignition without starting, and, just like always, the pump kicks in.

Don't you just love intermittent problems?

While we're on this subject, has anyone ever had one of these actually fail? (FinnTT?) What was involved in replacing it? Should it be replaced prophylactically after XX miles? (I would have put 4 x's to indicate at least the 1000s but there still may be AWOTs lurking, waiting to pounce on the desultory double entendre, attempting to match post with ripost. But I digress.)
