already posted this on bimmerforums so apologies if you read both but.....

I have noticed more fumes and smoke than I would expect so am suspicious that my DPF might have been removed by a previous owner.
It is too cold (meaning I haven't got the enthusiasm at the moment....) to jack up the car and inspect the dpf but I have done some diagnostics with DIS - see attached image.
Given the zero back pressure am I right in assuming there cannot be a dpf fitted? (no sensor errors reported)

Also, what is with the negative exhaust gas temperature? ambient was about 7degC, car only just started hence the low coolant temp.

Any comments?
