Hi

I bought my XF 2.2D (2013), about 3 weeks ago. Today we made a 250km trip with it.
I got a "Restricted Performance" messange and the car also lowered the power. Later I got a check engine light as well.
We reed the problems with OBD and I got 3 failure
-P0087 powertrain system
-P2263 Turbo/Supercharger Boost System Performance
-P2455 DPF Differential Pressure Sensor Circuit High

Can you help me what should be the problem?
The diesel filter, air filter, pollen filter, engine oil, differential oil was changed yesterday.

I got the same messange(without check engine) 1 week earlier, but a simple restart solved the problem, so I didn't pay for it too much attention, but now a restart and disconnecting the battery won't help either.
Which part will be the wrong one? Any idea?
