Citroen c4 1.6 hdi fault!!

Citroen c4 1.6 hdi 80kw 2006 manual.


Got the infamous depollution light on a dash, but no check engine light. Code reader read faults p1350 p1351 p1352.
Car has no loss of power or any other side effects, other than the "lim" in the wheel function doesn't work.


I've read lot's threads on the forum and that these faults are common, but it is really hard to narrate it down.

So maybe someone could quickly brief me about these problems and if I should ignore them.

P.S. Car in the last winter started just fine even in -25C weather. But the fault showed up after winter.
