A few days ago I've send my injectors to diagnostics and changed one of them but my car still produces a tinkle noise while I'am accelerating (and it has a little power loss in lower RPMs).
So I've created a little program which connects to EDIABAS server and collects informations (live data) from the car. I've checked air-mass, intake pressure and rail pressure. Only the air-mass shows differences. I've measured my brother's E60 too to compare the results and his air-mass looks ok.
I've tried another new MAF with the same BOSCH code an it has the same difference too. I've reset the MAF adaptation values in DIS but the same results. Here are the characteristic. My characteristic has a constant offset with both of the MAFs but I don't know why. Any idea? (Blue is the measured and red is the desired value)
