335 i cab rattle

[kayc]

My 335 i cab has got a really annoying rattle/squeek that develops at 70 mph + that appears to come from the nearside windscreen pillar area..Bmw have had the car for about three weeks trying replacement door panels,windscreen refit etc..anyone else had a problem like this or got any ideas what it maybe?..im losing patience rapidly with Bmw..the cars has only done 3k miles too..

Seal..??

Rattles/Squeaks on a new car is just about the most annoying thing ever!

I've got exactly the same rattle in my 330d - although it doesn't appear all the time.
It seems to depend on what road I'm driving on and the outside temperature.

I thought it was something behind the airbag pillar cover. Also the plastic surround above the instrument cluster has developed a slight rattle on certain roads.

Car will be going to dealer soon to have a headlight washer cover replaced and the washer bottle filter for the wiper jets cleaned, so I'm going to get them to take it out and have a listen - hopefully it will make the same noise on the test drive.

My brothers 330d coupe has exactly the same problem. If you find out what it is, I'd love to know. His is 8 months old and it's driving him nuts!

My wife's 320D cab did exactly the same - very annoying and I thought it was simply her car rather than a problem with others and never pursued it with the dealer as I really couldn't be bothered.

I have exactly the same. Mine develops at 75mph-ish

My old 3 series had a very similar rattle which I got fixed... I believe... if my memory serves me right... that the last one (which sounded identical) was the airbag gas canister vibrating against the metal bodywork inside the passenger side A pillar.

Not sure what they did to fix it but I suspect a couple of elastic bands around the canister would do it.

Can't guarantee it but worth suggesting to BMW if you take it in. I keep forgetting.

Well after a month of backwards and forwards it is now sorted..according to the dealer who have been very helpful to be fair,it appears to be loose trim under the wheel arch so as speed picks up air was getting through and causing a flapping sound inside the joint between the front wing and windscreen pillar..not sure how true this is but they re fixed the trim and the problem has gone for now...if it comes back i'll re-post..thanks for all the replies.
