Hello dear Volvo fans, I changed my head gasket for Easter (cooling water consumption).XC90 D5 200PS I also changed the flaps and the tube of the crankcase ventilation. Leak oil pipe of the injection nozzles also new. Everything again together and in its place. Complete suction track cleaned(sucked out) Unfortunately I had not immediately noticed that the pipe of the gas return to the exhaust cooler did not sit properly. We drove a few kilometers with it, my wife was Then I wanted to collect my son and motor went down into the emergency run with an indication of Orange’s warning triangle and emergency run. At home I heard then that the exhaust gas recirculation is leaking. Vida said: ECM 1507 Turbo Control-Too low pressure ECM 1517 Turbo Controll-Too high pressure I changed the pipe and deleted the fault memory. Now everything tight and also full power there, but when I drive in 6 gear 1800 revolutions it starts at jerkeli It’s like both tires have a little bump that runs exactly paralel. If you get gas it’s right away you go completely off the gas it’s also way. If you turn down it’s lower there. After the ride no mistake to find with Vida. Do you have an idea in which direction I could look for? Vida in English is there. I think it’s more like a smaller otherwise gäbs yes an error message. I hope for ideas and if someone knows and tell me k Where it comes from would be the biggest for me. MfG Christian
