Strange new noise from engine - 1998 911

Recommended Posts

After a rather spirited drive this morning here in South Florida, I heard a strange noise coming from my engine.  As my 911 is a Cabriolet, I first thought it was another car around me.    When I got back to the garage I confirmed it was indeed me :(

In summary:

  • The sound goes on for 30 seconds then would stop.  It would take another 2-3 minutes then it would come back on.
  • Something that caught me by surprise was that I turned the car off and was going to turn it back on to see if it continued.  When I just turned the key to turn-off the engine immobilizer the sound came on even though I had not physically cranked the engine yet.
    • When I started the engine it did not come back on.   I let it run for another 5 minutes but the noise did not return
  • I checked to see if it was throwing any ODB2 codes with my Durametric, however, all was clear.
  • Oil levels are fine
  •  
  • I have enclosed two videos
    • One is with the engine running (and the sound disappearing)
    • The second is when I turned the key, but not yet cranked the engine.

 

Any advice/insight into what it could be would be appreciated.    Also would like to know can I drive it to my mechanic (assuming that I would need to), would I be causing any long term problems?

 

Thanks - Steve
