Hi all, i hope you can help me as i dont know were to look anymore. Every acceleration i get the spiral blinking and the code is p227900 intake air leak. I had the whole engine out as i was doing big service and wanted to check all hoses and both egr valves and everything. All is good to the eye, almost no soot, all hoses look perfect.
Car goes like it has only 100kw and when i get the spiral wont go over 60mph.

I searched all over google and nothing really helps...
Its quite a new engine CNH and it has a chargecooler.

Thanks for all your help.
