Undertray cooling ducts,one or two?
I was changing the oil yesterday on my 2006 S65 and noticed one of the tubes on the undertray was missing. As a reality check does everyone out there have both tubes attached to the undertray, or just one?
I believe they are used to provide cooling air to the tubine housings.
To be a bit more specific, the part in question is attached to the flat undertray that you have to take off to get to the oil pan under the car. When you remove it there is one long plastic tube that goes up near the turbine housing. From the bottom of the car you will see tho NACA ducts on the tray and they attach to that. I think there used to be two but I can't remember.
Anyone know if they should both be there? Only the driver side was still there.

Hmmm... I wonder if the dealership took it off and did not replace it?? I guess I will need to see if I can find another one. I will look on STAR to see if I can find the diagram to show them when I try to order one.
Thanks for the info!

Thanks for the picture! I wonder if I can order just one side? I will have to see if I can track down a part number.
Did it have a reference to the #3 item in your picture to as what it is called?
Thanks again.

It didnt have any reference other than "Cooling tubes". Probably a dealer part only for sure..just for grins, did you check farther back on the other covers? Maybe it just became dislodged while friving and has moved its way back and is sitting in one of the other covers by the tranny, etc.
I had my lower cover off a few months back for a transmission fluid change and remember that they arent very substantial and just kind of sit on the lower cover.
