Hi, Chris. Is your problem still exist? Have you checked your lambda probe's wiring? Colouring of the pre cat lambda : 1 - brown; 2 - blue+red; 3 - orange+violet; 4 - orange+green; 5 - orange+brown; 6 - orange+brown.

Hi ChrisMG. After about 15 minutes the engine controll module should be in closed loop state. From this point the engine will start using the sign of the front oxigen sensor. If your oxigen sensor is not working at all, i think the engine will probably stop, but I'm not sure. According to your fault codes linked before your front oxigen sensor isn't working. I suggest you to check the cables and wiring before buy a new one. I attached for you a schematic for this engine. You can find the oxigen sensor on the page three, with the mark of B72-I. I suppose the label of the wire colors are in german language. In the schematic you can see that the sensor heater circuit supply is on the Fuse 9. You should check this fuse first. Have a nice day! elshemecu1416v.pdf

Hi friend. Sorry to say that, but you gave so many confusing information. Read faultcode from ecu via OBD and post it! Was your engine running with low oil pressure for a long time? If yes, it can lead to mechanical damage! Anyway tons of failure can cause idle problems such as dirty throttle body, dead ignition coils, stucked, opened EGR, leaky intake manifold etc. And of course idle problems usually comes when the engine is warmed up. Maybe you should take the car back to the service station.
