Wind deflector flew off at speed

[Msport]

Not long had my Z4, and had the roof down for the first time yesterday with this beautiful sunny weather 8)

I was enjoying the open roof driving experience, accelated sharply up to about 80mph (private road :wink: ) and the wind deflector flew off, fortunately landing inside my car!

Why did this happen, should I only have the wind deflector up at low speeds or does it sound like it wasn't fitted properly?

I've put it back on but I must say it does seem like a pretty flimsy bit of kit, especially given the price of it :?

is this a perspex one that you velcro on ?

 

[Msport]

No I think it's the original optional extra BMW one, it's black mesh and the head tubing has slots it inserts into..

is this a perspex one that you velcro on ?

I think it should withstand high speeds without a problem. I too have driven fast with mine on a few... ahem, private roads, and it’s held fine.

It is a bit tricky to locate properly however, so I think this is probably what the issue was with yours. Check your handbook for the correct procedure but I’ve also attached a pic of the appropriate page which helps with a few diagrams.

E85 not E89' but I have seen 165+ on the clock, with the roof down. So either damaged or not fitted correctly, would be the likely cause. :wink:

Awesome, thanks very much for that- really helpful as I'm away and don't have my manual on me this weekend. Will follow the guide and hopefully that's the end of it flying off

Make sure it's fitted the right way round or its possible for it to fold

German autobahn nodoubt, as I’ve had no issues in my old 3.0 testing there at 150, though steerings not as planted as the M

I think this is probably the answer.
Ours was fitted wrongly when we picked it up and the same thing happened.
It was only after refitting it that I noticed that it fitted better than it did before.
Hasnt done it since.

Off-topic but it's beyond me why there are coat hooks in this car - especially in the place they've put them!
