BMW GT1 diagnose.
I have just made a diagnose test with my GT1 scanner. I got these fault codes. I have attached some pictures of the fault results. Hope somebody in here could help me out a little bit.
The reason that i made this diagnose test is that my car began to have a strange idle, when i rev it, it first get down on 1300 rpm and then it very slowly gets down on normal 680 rpm . It startet to do this after i replaced the fuel pump because that the old one stoped working. So i changed both the fuel pump and the fuel filter. The new fuel pump is a siemens pump. And the one that was in the car before was a Bosch pump. Dont know if this have anything to do with it. I also added some fuel cleaning liquid, and i added a botle of it. Maybe this have destroyed my oxygen sensor?. Because i added a whole bottle in only 10 L of Fuel. And the label said to add the bottle to a full tank 60 L.
I have cleaned the idle control valve, and the air mass sensor. The faulty code for the air mass sensor is because i unplugged the sensor. Now the fault is not present. But fault 70 and 201 is still there.
By the way, i have also just changed the spark plugs and air filter. And checked for any vacum leaks, but there wasnt any.
