Whining noise at speed

[alexe]

Hi folks,

I took the mrs car out last night and noticed a very loud noise when approaching 80ish on the motorway. It seems to come from the vent on top of the dash and wondered if anyone else has experienced this and knows of a cure?
Thanks in advance

its an R53 cooper and the only body enhancements are factory fitted side skirts.

strange doings are in our midst.
Took the car for a good blast last night, often reaching speeds where this would typically have been a problem......and no noise.

I am beginig to suspect iut doesnt happen if the car has been warmed up properly before hitting 3 digits - is this possible?

This is outrageous! a car bought from new with a fault that only manifests over 70mph will never be fixed! I cant believe the cheek.

If this proves to be the case when we take it in to be serviced i will camp outside the stealership to warn people off making a purchase.

Just my little rant for the day
