BMW GT1 diagnose.

[00marcus00]

Hello everybody

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.

the siemens fuel pump has the same psi?

Actually i dont remeber how many psi the original was. But the shop who sold it to me, said that it should fit my car. Because they looked the same, the only difference was that the pump brand was not the same.

do you think that it could be the pump?. Remember it is siemens so its not a cheap model. How many psi should it be?.
