Piti muuten nämäkin googlaa uudelleen kun en nyt ihan tarkkaan muista mitä ne tarkoitti.

P0400 Exhaust Gas Recirculation Flow Malfunction:
Exhaust Gas Recirculation (EGR) system is a part of the vehicle emission control. It directs a portion of exhaust gases back into the engine intake to lower the combustion temperature, read more below. The code P0400 is set when the EGR system flow is less than expected. Usually this happens when carbon deposits (soot) clog up the EGR system passages and tubes.

Tuo viimeisin herja on vähän nihkeä kun syy voi olla ilmeisesti hehku tai tuo kaasupolkimenasennontunnistin. Ilmeisesti. Mut nuo kolme ekaa liittyy kaikki egr ongelmaan. Jos käy ohjelmoimassa koko egr:n mäkeen niin veikkaan noiden kolmen herjan poistuvan. Mut en tie oikein mitä tuolle viimeiselle sit tekee..
