Whistling noise at dashboard area
Hi all
I hear a whistling noise that seems to come from my XK 2008 dashboard area.
It changes and follows engine revs. It's present without A/C and radio/CD. Never stops while engine is on.
Attached a short audio file over several locations around the dash
Any idea what may be the source ?
Thanks

1. Find the engine air intake black plastic tube which runs along the front of the engine. Note that it has a rubber hose which connects to the engine compartment firewall. That hose transmits sound.
2. See if you can hear this whistling sound while you are standing outside the car, the hood is open and the engine is running. If you can hear it, try to localize the source of the sound. Maybe you have a slight leak in the air intake which allows the whistling to develop.
3. Disconnect the rubber hose mentioned in #1 above and see if that affects the whistle as heard in the passenger compartment.
I do not hear a whistle sound in my 2007 XK.

The hose that leads from the intake air box/tube to the firewall is only there to provide intake sound, so the you get a "sportier" sound in the cabin. I found it anoying (eventhough mine is a vert) and pulled the hose off, pushed a wine cork in it (being careful to not shove it in too far to easily pull back off) then reassembled the hose to the intake air box. The result was a much quieter cabin with the top up and might stop the sound you are experiencing. If I'm off base on what you are seeing please excuse my post.
If you disconnect it at the air box you have to cap off port so as not to allow unfiltered air into the intake stream.

I made sure the cork was clean, ie. not flaking little pieces off, slid it into the airbox port then reattached the hose. I have a hose clamp tool that allows the clamps to not get damaged so that made the job a breeze but, as you probably know, pliers will do the trick too. I also made sure the cork only entered the port part way so that it was easy to remove if I wanted and also did not enter the air stream within the air box. The cork was a tight fit so I was confident it wouldn't work it's way forward into the box.
Hope that helps.
