Air Vent Noise by Jupiter

The car is a 2004 Facelift Connie SE. I get a " Humming / Slight Whistling " noise, which seems to be coming from the central air vent area. This only starts when the car reaches 65 to 70 mph. Sometimes a bit lower when there is a strong headwind. Any alteration to the air or vent settings make no difference.

It is driving me nuts !!!!

Anybody got any ideas as where to start looking. ??

I heard it today in my 75. When I put pressure under the black top of the dash, it stopped. Its was vibrating. I'm sure someone on the 75/MG site said they placed a little piece of padding somewhere and it never happened again. Might not be the same problem but I only heard it from 60 mph.

I've got something like this on the 260, when the blower is on there is a definite rustling, nowhere near as quiet as the cdti ?

I think I have located the culprit. I went to do my monthly " Plenen " check and on removing the passenger side outer grill ( under the bonnet ) I found it was badly cracked. Also the inboard fixing clip was broken. Off to the scrap yard for a replacement and made sure it was fitted correctly. Took the car onto the M8 and up to 70mph with no noise . Then up to 80 for a short belt and still no noise. So here's hoping this is the fault.
Thanks to all for advice. Forum is great for assistance.

Planning is an unnatural process, much better to just get on with things, that way failure comes as a complete surprise instead of being preceeded by a period of worry and doubt
