My Ride: 530D SE

Occasionally (once a month or two?), my 530D performance changes during a journey. There is a noticeable additional lag when you accelerate and also there is a "throaty" exhaust tone from somewhere underneath the car (as if it were blowing from a hole, but I don't think it is?). If I park while it's doing this, there is a distinct rubber smell from under the car. It's done this for the last couple of years (& is today) and it's bugging me!
Any similar experiences out there or ideas?
Thanks.
Ian.

I've got the filter, so it must be this cleaning process. Any idea how it works???
Thanks.

Mine sounds like I have a hole in one of the mufflers but quickly goes away.
Ditto on the weird smell too.
