If you had INPA or DIS, you could drill down in the software to help find your problems. Until you learn how to use the software, it is a bit confusing. There are many test you can run, to check to see where the problem is. The only way to learn how to use the software, is to start experimenting with it. If you think like a German, your learning curve would be accelerated a lot! Read below for more on this !

When the engine starts cold at 1500 RPM, the car is in the open loop mode. Once the O2 sensors & CTS have been satisfied, the engine goes into the closed loop mode. At this point all fuel & air is controlled by the ECM.

Hope this might help!
