My T5A (48K) sometimes has a noise from under the hood that does not change with speed and goes away after driving about a city block. It sounds like a fan roar but all is tight. I have an extended warranty but of course it will not act up at the dealer. Has anyone else had this problem?

Thanks,
old bear

My '94 850 Turbo did this on cold starts, but it was related to the turbo whining when cold, once I got a 1/2 mile down the road and the engine warmed it was fine. Dealer told me this was normal on cold starts, so I would sit for a minute or two, and did not push the engine until I got some heat moving to losen up the fluids running with the turbo.

I think I have a simialar noise. Mine kind of sounds like an electric whine with a kind of whistle. Almost sounds like the fan motor is trying to run but the fan isn't actually turning. I've noticed it after starting in the morning but lately have noticed it periodically after driving. Anyone else hear anything like this?
