Hello everyone,

I have a 900 SE convertible with a very boring problem. When driving at
around 130 km/h (80mph), the bonnet begin to whistle loudly, and just
nothing else before.
The sound come from the middle of the windshield frame, just above the
mirror.
I don't know what to do to prevent that whistle, except open the bonnet :))
It has arrived a few times ago, one day, like that.

Did someone had the same problem ? What did you do ?

Many thanks,
Philippe

Well, now you are really confusing me... I thought that "bonnet" was
the euro term for "hood" here in the US, but I'm thinking what you mean
it is the soft-top, since I can't imagine driving a car with the engine
compartment hood open... ;-)

In terms of localizing exactly where the noise is coming from, with
judicious (temporary) use of masking tape you should be able to find
where the air leakage is occuring at, and then it is simply a matter of
fixing or beefing up the weatherstripping at that point.

Correct, I talk about the soft-top. Hard to find the good technical words
for a poor lonesome frenchy ;)
And sorry, but what do you mean by "beefing up" the "weatherstripping" ?

Many thanks,
Philippe

You may need to either replace a section (if it is worn or damaged) or
augment the existing weatherstrip with a second one.

Thanks again for your answers.
I'll try that as soon as sun comes back :)
