It's a straight four pot. Having Bank 2 pop up would be something of a surprise  ;)

I think thats a DPF pressure sensor generic code, needs reading with a tool more customised to the Manufacturer to get the sub code and more detail

Just had a little chat with a PT contact here.

Apparently Shitroen use the very poor Conti NOx sensor setup which has a sensor and mini ECU located close together, he says the ECU is very pronce to water ingress and is likely the issue. Apparently they come as a matched pair (ECU and Sensor).

Being a NOx sensor it should easy enough to get at and change, the cost however might be a few hundred quid for the part

No, every time the crappy designed Conti NOx ECU gets a soaking.

Needs changing, or your trip will be a wasted one  :y
