Rattling noise at glass window - Cab Problem?

My 325 Cab has rattling noise on driver and passenger glass window when driving over uneven road surface. Even average speed like 50-60km/h over small bumps.

PML svc say warranty dont cover this. We have to maintian the rubber seals all round on our own using rubber care solution/spray.

Can this really be solved?

i think BMW does sell this gummi fledge thingy that's reported to work on overseas forum. since they're not willing to cover it under warranty, you don't really have much choice but to try it out right?

any excess you can apply on your Z4 as preventive maintenance.

i have htat even on my sedan. its a kinda creak creak sound as the raods become uneven. I heard this is an apparent problem on all E46s. e46fanatics has this problem in detail and is apparent in alot of markets.

The rattling is normal for soft-top bimmers - cabs or roadsters. Either you minimise the squeaking by maintain the seals and joints with rubber creams, or use black seal tapes (for noise reduction) to minimise the friction. Can DIY on your own, just be cautious on the waterproofing part.

If your car is stiffened with strut and ARBs, the rattlings could be worse.

Bought the silicon spray from Carrefour and did minimise the noise.

Looks like have to apply several times.

Just now went for car wash and the noise comes back again, hmmmm?

OWS does have a spray called "Body Flex" - has anyone here tried that?

BMW can take a page off Toyota; the IS250 I test-drove was silent as a grave!
