Ecosport diesel particulate filter pressure issue

I've got a 2007 Ford Ecosport, diesel engine, with about 187k km on it. Recently, the engine warning light popped up. I've noticed a serious dip in power, plus I'm getting smoke when I accelerate, and the exhaust smells awful. I scanned it and got a 'diesel particulate filter exhaust pressure too low' error. Could it be a blocked DPF or maybe a dodgy sensor? I suspect the exhaust back pressure sensor is faulty. Anyone dealt with this before?

Sounds familiar. I had a similar issue with my old Opel Astra, though it was a petrol engine. I had the engine light and loss of power. The garage mentioned something about exhaust back pressure, but I didn't get into the details. What kind of driving do you mostly do?

Mostly city driving, short trips, unfortunately. Does this mean I should try a forced DPF regeneration or something? Or is it more likely the sensor itself is the problem?

With that driving pattern, it probably didn't regenerate enough. However, in my case, they kept mentioning the sensor itself failed. They replaced it, and the problem was gone. To be honest, I would bring it to a workshop to have it checked out.

Thanks for the advice! Just got it back from the workshop. Turns out it was indeed the exhaust back pressure sensor. Replacement and all cost me 245€. Running smoothly now.
