Hi Everyone! I have question about this engine and starting it at low temperatures because a lof of people complain on this problem. I have checked all possibility: change glow plugs, egr off with (mechanically), change filters, aku, check the fuel system and everything is ok. Whether it is possible to add more fuel on start (maybe load new ecu map?) and Can I do it throught OBD (with diagnostic cable) + special app or I need to buy IDS or something similar?
