Mystery Sound

christopherkriens · 07-11-2012, 10:58 PM

Coming from the engine bay- passenger side near the cabin. No codes recently, sounds like a pump. Any ideas? Sounds like this: wah wah wah wah wah wah wah wah wah

sounds like a UFO

does it change under load? revs up etc?

It's only audible at idle, but if I rev and let it come down it does vary a little. Wasn't doing it this morning.. hmmm..

Really odd. No codes or anything?

I did get 2C58 the other day, but this is one I get occasionally with the JB3.

+1 ^^^ that is a new one for the books. Let us know what the dealer says and hopefully they won't say "Cannot duplicate the clients concern" or "that is normal".

While the engine is idling and making the noise crack the oil cap loose just enough to break the seal. Does the noise go away? If so take it to your dealer, there is a bulletin on this.
