whining whistling noise from front anyone?

Hallelujah!!! Found it!!!

Did the trick with clingfilm and the same part of the bumper is to blame. I am soooooo relieved. I was tempted to sell the van at one point.

So exactly what is it that is causing this? I can feel the foam inserts behind the bumper are loose.

I remember having this issue with a car, turned out to be a little piece of dirt that had accumulated on the ambient temp sensor on the bottom of my wing mirror!

Picked it off and the whistling that had blighted me for weeks was gone!
