Hi, I read out my injectors yesterday because I heard a metallic flap from the engine compartment when I was in cold engine and outside temperatures around 15 degrees when I was giving gas and the engine jerked in the speed range 1200-2000 revolutions. Speed indicator did not wobble. When the engine has reached operating temperature, the noise is almost gone and the jerking can no longer be felt. The values can be seen as shown in the appendix. Starting from the limit values for calibration points 1 and 2 of the respective injectors (-45ms and -15ms) shown in the web, at least the injectors 1 & 2 are worn out. The injector 4 is close to the wear limit. Or do I see the wrong thing? The car is a passat B7, 140hp, switch, BJ2011, Mj2012 and has about 159500Km down. How is your opinion?
