I notice the clamp is leaking, I tighten the bolt a little and it did not help.

If I want to replace the clamp and gasket inside , do I need to remove the DPF?

Has anyone done this and can share the experience. I saw the clamp seal is tough, have to align up the flanges properly.

I was thinking maybe the DPF need some cleaning too?

I think the clamp is not designed properly. the ends on the clamp bends easily and too flimsy for the job. BMW is learning a lot from China on the material quality and material gauge, but not on the price.
I just replaced the plastic valve cover. The plastic crack easily. Even the new ones stored in the warehouse deteriorate overtime. After I solved the oil burning issue, I noticed the exhaust leak. Both are due to cheap material and light duty design.

I remember breaking the clamp when I was removing the dpf. It was flimsy indeed. It was not supposed to be removed, just undo and redo it.
