Another Weirds Noise from the Rear ( trunk ) - BMW Forum

fasaavedra4 · 08-03-2009, 09:18 PM

I have this weird noise coming from the rear, i would say something around or underneath the trucnk, it is been there since a long time ago.

When in reverse and when turning either left or right at slow speed ( so you can hear it ) a CRACK noise comes up, likes from the rear....

So , when the car was under warranty I took it to the dealer, they said they repaired something related to the differential and bla bla bla as usual with them, of course they did not because came up again while warranty had expired.

Does anyone has this issue on your E46 ? any idea what it could be ?

I'd have the subframe checked for cracks.

it was checked by my mechanic whom removed the CDV and he said subframe was OK.

It has to be something different than that.

Is it possible that thee differential mounts are lose on the sub frame itself?

then, is this something related with this Big issue with the subframes of the E46 that is at court with Bmw USA?

Is it something expensive to have repaired?

From my understanding, BMW settled and said they would repair sub frame damage for free. Read about the settlement here. I'm not sure the problem you are suffering from is subframe related though because if your subframe was cracked I'm pretty sure you would know.

I would definitely get it checked though. If this is something that is constant I can tell you it has the potential to get worse.

ok...i would have the car checked.

Perhaps you know.......i read the link you wrote, but it does not says what will be the procedure for us to have these cars checked..... I guess all E46 owners should contact their local bmw dealers and schedule an appointment? since when they are committed to permor these inspections?

I remember reading something more official on this matter. Let me see if I can find it.

BimmerE39 · 08-03-2009, 10:39 PM

That was easy. Click Here According to what I've read, you should have received a letter about the settlement.

thanks Bro...

No problem. I hope you find the problem but it does sound to me like the diff might be slightly loose from the physical subframe.
