How can I check if my car has a DPF or not?

On the subject of DPF removal, which you covered recently, how would I know if the DPF is still intact on my car, a Citroen C6 2.7HDi? I read that it can be removed and everything welded back so as to look like it was never touched.

As I purchased the car second hand I do not know the history of the DPF. Surely if this item has been removed prior to my ownership I could not be held to account?

Specialist emissions testing would show this up.

It looks and drives like a big Citroen should - idiomatic, smooth and very hushed. Plenty of high-tech gadgets. Excellent crash safety ratings.
